All habits at a glance
No icons match — clear the search to see all.
Optional: a different goal for certain days — the day a fast ends on. Empty days use the goal above.
Daily habits — tap the big circle on a card to check the habit off for today; tap again to undo. The flame shows your current streak: consecutive scheduled days completed. Today doesn't break the streak until it's over.
Habits with several parts — name a habit with vertical bars, like Medit | Brea | Cold, and the app tracks each part on its own. The number of taps on the big circle picks the part: one tap toggles the first part, two quick taps the second, three the third. While you tap, the part you're about to toggle lights up, so you can see the count landing; a moment after your last tap it registers, and a bar confirms it (“Brea done”) with Undo. Done parts are written in the habit's color, the others stay gray, and the circle is checked as soon as any part is done — so streaks, week dots and the day bar count the day as complete. You can also tap a part's word directly to toggle exactly that one, and swiping the card to the right marks all parts at once. Two, three or four parts are supported.
Parts on an earlier day — press and hold the big circle of a multi-part habit and a small sheet opens for yesterday with one button per part: tick the ones you did and save, so a day can hold just Medit and Cold. The same sheet opens when you tap any day in that habit's calendar, which is how you correct a day further back — it opens with that day's parts already ticked. Saving with nothing ticked empties the day, and “Mark as skip day instead” excuses it (holidays, illness). Every change shows an Undo bar, and days filled in this way never trigger a milestone celebration.
Weekly-target habits — for things like working out, where it's the count that matters, not the day: set a target such as 3× per week and check days off whenever they happen. The Today card leads with this week's count — “4/6”, with “this week” under it — and turns green the moment you reach the target. Under that, in smaller type, the flame counts weeks in which you hit it; the running week never breaks that streak until it's over. A habit already running as a daily check can be moved onto a weekly target at any time without losing a single tick — see Changing a habit's type later.
Start/stop habits (intermittent fasting) — the same button does both: tap in the evening to start the fast, and tap when you eat again. While fasting, the card shows the live elapsed time; after stopping, it counts the eating window and shows how long it lasts — “6:22 eating, until 19:01” means the eating window closes at 19:01, the moment to start the next fast if you want to keep a steady daily rhythm (the window is 24h minus your goal). Once that time passes it says “time to fast”; after a full day without fasting the card falls back to showing the last fast's length. A fast running past 24 hours turns amber and asks “still fasting?” — tap the timer to fix a forgotten stop. A fast counts for the day it ends on. Set a fasting goal when editing the habit — and, if you like, a different goal for certain weekdays (seven small fields under the goal; the goal belongs to the day a fast ends on, so Friday's number is for the fast you start Thursday evening; empty fields use the main goal). The ring, the countdown, the “until” time, and the green/gray calendar circles all follow the day's own goal, and a per-fast goal chosen at start still overrides everything. A ring fills around the button as the fast progresses like a traffic light — red for the first third of the goal, yellow for the middle third, green for the home stretch — while the card counts down how long is left and shows the clock time (24-hour) at which you'll hit the goal (e.g. “2:30 left, goal 11:30”). Everything turns green when you reach it.
Editing a fast — forgot to press start or stop on time? While fasting, simply tap the running timer number on the Today card to correct the start time. All fasts can also be edited from the detail view's list (including the one in progress) — start, end, or delete.
The fasting card's tap areas — faint dashed lines on the fasting card mark its separate touch zones, and a tiny word under each says what it does: start (or stop while fasting) under the round button, stats under the middle, which opens the habit's details, and edit under the timer number on the right. While a fast runs, edit fixes the running fast's start time; between fasts it opens your most recent fast, so a wrong stop time is one tap away from being corrected. The lines and words are only a hint of where each zone begins.
Week dots — the M–S dots show this week (Monday first); filled dots are completed days, dimmed dots are days the habit isn't scheduled. Each dot is also a shortcut: tap one and the habit's calendar opens on that day, briefly flashing it — handy for checking or fixing a specific day of the week.
Fixing the past — in a habit's detail view, the month calendar is editable. For daily and weekly habits, tapping a day cycles it: done → skip day → empty. (For a habit with several parts, tapping a day opens the part sheet for that day instead of cycling.) A skip day (shown hollow with a dashed outline) is excused — it neither breaks nor extends a streak, and it leaves the completion count — perfect for holidays or sick days. For fasting, tapping an empty day opens a small sheet to pick or type the hours (or mark a skip day); tapping a day with a recorded fast opens that fast in the editor, where you can adjust its start and stop, delete it, or cancel — nothing changes until you save. Use the arrows to move through months — up to a year ahead, so a planned vacation is visible; future days are locked except vacation-marked skip days, which a tap un-marks. Once you've wandered off the current month, a target button appears in the calendar header — one tap jumps straight back to today. Streaks and stats update immediately.
Vacations & sick weeks — under the month calendar, “Skip several days” marks a whole date range as skip days at once: pick the first and last day (future dates included, up to 92 days), and tick “Apply to all habits” when the whole life pauses, not just one habit. Days already done stay done, and the Undo bar takes back exactly the days the range added. A planned range shows up on the calendar right away and can be checked in the months ahead.
Forgot yesterday? — press-and-hold the check circle of a daily or weekly habit to mark yesterday done, without opening the calendar. A short Undo bar confirms it (or tells you yesterday was already done). On a habit with several parts, the hold opens the part sheet for yesterday instead, so you can tick only what you actually did. A normal tap still checks off today. Backfilled days never trigger milestone celebrations.
Week in review — each Monday, a “Last week” card appears under the habit list on the Today screen: per habit, how many scheduled days (or weekly-target check-offs) you managed, how your streak changed over the week (green +, red −), and for fasting the number of fasts with the average length and how it compares to the week before. Tap a row to jump to that habit; the dismisses the card until the next week starts, and Settings → “Show week in review” brings it back any time. When a new month begins, a bigger sibling appears the same way — “August in review” — with each habit's days completed and longest run of the month, weekly check-off totals, and for fasting the number of fasts and average length compared to the month before. Both cards are pure summary — nothing about your data changes.
The weekly report — the “Last week” card comes up by itself the first time you open the app in a new week, and its one button, Last week, opens the analysis, where both ways of sending the week now live. It turns the week into a picture: each habit with its seven days as coloured squares, what you managed (“6/6×”, “5/7 days”, or the week's fasts and their average), how each streak moved, and a headline saying how many habits hit their target. On iPhone it opens the share sheet, so it can go straight to Messages, Mail or WhatsApp; elsewhere it saves as a PNG. Settings → Send last week's report does the same thing whenever you want it, including after the card has been dismissed.
Last week’s analysis — Read last week’s analysis on the “Last week” card, or Stats → the same words, opens a written summary of the week that ended, dated to that week. It is written, in paragraphs: what happened, whether that was any good measured against your recent normal, what the last eight weeks show underneath it and what to do about that next week, and one habit idea. Under the summary sit both ways of sending the week: Send this summary as text hands the words to the share sheet, so it can go by mail or message, and Send the week as a picture hands over the drawn report. The labels name the form because two buttons both saying “send this” would say nothing about which is which. Under the text, the cards are still there: How it went and What to try next week, one per observation in its habit's colour and tappable through to that habit, then Something new? with three habit ideas and a button each. The words and the cards say the same things on purpose — the text is what you read and send, the cards are what you scan. The week you are currently in is not on this screen: its count is on the Today card, where you are looking anyway.
Last week and next week are different questions — the “Last week” card and the report picture give you the week's figures; Last week on this screen says whether they were any good, which is the thing the numbers on their own never tell you. It compares one week against your recent normal, so it only speaks when something stood out: your best week in two months, the first time you made the target since August, a run of clean weeks ending. An ordinary week gets no sentence. What to try next week is the opposite — it ignores any single week and reads eight of them for a pattern, because a bad week is not a habit and a habit is invisible in a single week.
How the notes are worked out, and what they will not do — there is no intelligence behind them and nothing is sent anywhere: the app does arithmetic on what is already on your phone and picks the sentences that fit. So every note names the figure it came from — “4 of your last 8 misses fell on a Thursday” — and you can disagree with it. The thresholds are set high on purpose: most notes need several weeks before they will say anything at all, because a confident sentence about a coincidence is worse than silence. When there is nothing honest to say, the screen says that instead of filling the space. Two things it deliberately never does: call a weekly target's rest days a slip (six out of seven means one blank day by design), and tell the same story twice about one habit.
Habit suggestions — three at a time, rotating each week, and anything close to something you already track is left out. Add this habit opens the ordinary new-habit sheet with the name, icon and target filled in: it is a starting point you can change, and nothing is created until you press Save.
Why it cannot send itself — an installed web app gets no time to run when it is closed: iPhones give it no background execution at all, so nothing can happen on a Sunday evening unless you open the app. And your data is only ever on this phone, so a mail server somewhere would have nothing to report on. The picture has to be made here, by you, with one tap — which is why the card puts itself in front of you at the start of each week rather than waiting to be found.
Fasting stages — the fasting detail view shows the commonly-cited phases of a fast on a colored track: Digestion (0–4h), Settling in (4–12h), Fat burning (12–16h), and Deep fast (16h+). While a fast is running, a marker sits at your elapsed time, the current stage is highlighted, and a line names it (“Now: Fat burning”); it moves along live. This is a popular approximation from fasting literature, not medical advice — every body is different.
The fasting calendar — for a fasting habit, each calendar day shows the date with the fasted hours in a circle beneath: green when that day's goal was met, gray when the fast fell short of it, red with a live count for today's fast in progress, and a dashed circle with a dash (–) for skip days. A one-line legend under the calendar explains the circles right where they appear. The Fasts card counts how many days met the goal.
Day notes — tap the pencil in the calendar header to enter note mode, then tap any day to write a short note (“skipped, travel day”, “hard fast”). Days with notes get a mark, and the month's notes are listed under the calendar; tap one to edit it. When today has a note, a small dot in the habit's color appears next to the name on its Today card — tap the dot to read the note, with an Edit button right in the bar.
Tonight's goal — press-and-hold the fasting habit's start button to pick a goal for just this fast (13/15/16/18h or the habit's default) before it starts. You can also change the running fast's goal by tapping it in the detail list. The ring, countdown, and goal time follow the per-fast goal.
Details — tap anywhere else on a card for the year-by-year pixel grid, current and longest streak, and completion %. Small letters mark where each month begins, and tapping any pixel shows that day's date, status, and note. Timer habits also list recent fasts with average and longest duration.
Year poster — the share button next to a year heading in the detail view turns that year into a poster image: the habit's icon and name, all 365 days as a month-by-month pixel grid in the habit's color (skip days dashed), and the year's headline stats underneath. On iPhone it opens the share sheet, so the picture can go straight to Messages, Photos, or Instagram; elsewhere it downloads as a PNG. Past years get their own poster with days-done totals.
Undo — starting or ending a fast, and removing entries, can be taken back for a few seconds via the Undo bar at the bottom of the screen, so a stray tap never costs you anything.
Swipe to act — on the Today screen, swipe a card to the right to mark the habit done for today (for fasting: it stops a running fast, or opens the record-hours sheet when none is running), or swipe left to excuse today as a skip day. A colored ring shows when the swipe is far enough to fire, and every swipe action has the usual Undo bar. Days already done or skipped just tell you so instead of double-applying.
Drag to reorder — press and hold a card until it lifts, then drag it up or down the list (works in the grid too) and let go. The new order is saved immediately, with Undo in the bar; Settings → Reorder habits still exists for precise arrow-button moves. The press-and-hold shortcuts on the round button itself (yesterday done, tonight's goal) are untouched — the drag starts on the card body.
Text size — the app follows the iPhone's Display & Text Size setting: make text larger (or smaller) there and every screen scales with it, icons and buttons included.
Gestures — swipe the month calendar left or right to change months, and drag any bottom sheet downward to close it. The Today header shows the day bar: one segment per habit scheduled today, filling left to right as you check things off, with the filled color moving from red through amber to green as the day nears complete. When the last scheduled habit of the day is checked off, the bar celebrates with a brief pop and a hand-drawn checkmark. Screens slide like native iOS: details and stats push in from the right, going back slides home from the left (both stay still if the system's reduce-motion setting is on). The settings, stats, and add buttons float at the bottom of the screen, within thumb reach.
Reorder, layout & theme — Settings → Reorder habits moves habits up and down the Today list; Settings → Layout switches between the list view and a two-column grid; Settings → Theme picks auto (follow the system), always light, or always dark.
Icon badge — on an installed app, the home-screen icon can show how many scheduled habits are still open today. An iPhone only allows this once you have said yes to notifications, so it is off until you switch it on: Settings → Show the count on the app icon, then allow the prompt. (Before v1.29 the app simply tried and failed silently, so the badge never actually appeared.) It updates whenever the app is opened or used — a web app can't change it in the background.
Archiving — done with a habit but want to keep its history? Archive it from its detail view: it disappears from Today but keeps everything, and can be restored any time from Settings → Archived habits. Deleting, by contrast, is forever.
Adding & editing — ＋ creates a habit with a name, icon, color, and type; the icon picker offers 40 hand-drawn icons and a search field that understands English and German words (try “kaffee” or “sleep”). A live preview at the top of the sheet shows the card exactly as it will look on the Today screen — it follows every keystroke of the name and every icon, color, type, and weekday choice. Daily habits can be limited to certain weekdays. The pencil in the detail view edits it.
Changing a habit's type later — a habit that turned out to be the other kind can be switched: edit it and pick Daily check or Weekly target. Every day you have already ticked stays exactly as it is — both kinds record the same thing, one mark per day, and only read it differently. Going to a weekly target starts at the number of days the habit was scheduled for, so a seven-day habit offers 7× and you tap the number you actually want; the streak then counts weeks that reached it instead of days in a row. Going back the other way counts days again. Start / Stop is the exception and stays fixed: it keeps start and end times rather than days, which the other two have nowhere to put.
Stats — the chart button on the Today screen opens an overview of all habits: current and best streak, this month vs last month, and the last 30 days as a pixel strip per habit. When your current streak comes within 3 days (or 1 week, for weekly habits) of your best, the card adds a line like “2 days to your record” — a small extra reason not to break the chain. A fasting habit with at least five recorded fasts also gets a rhythm card: your usual start time, your strongest weekday, your average fast, and a Mon–Sun bar chart of average fasting hours per weekday — the calendar knows your pattern, this card tells it. At the top, the Achievements card keeps what the confetti celebrated: earned streak milestones per habit, your longest fast, best streak, and total days tracked.
Milestones — hitting a round streak (7, 14, 30, 50, 100… days, or 4, 10, 26, 52 weeks) or setting a personal-best fast earns a short celebration. Each milestone fires once.
Fast chart — the fasting detail view charts your recent fasts as bars against the dashed goal line, so the trend is visible at a glance; tap a bar to edit that fast.
Voice commands (Siri) — as of iOS 2026 releases, Shortcuts cannot open an installed web app: the “Open App” action doesn't list it, and “Open URLs” lands in Safari, which keeps a completely separate copy of your data — so a voice or Lock Screen launcher isn't possible yet. The practical setup is the app icon in the Dock; the icon badge shows the day's status before you even tap. Worth re-trying after each iOS update: if “Tracking” ever appears in the Shortcuts “Open App” picker, a “Hey Siri, Fasten” shortcut and a Lock Screen button will work immediately. (The ?fast=start/stop/toggle web commands exist for platforms where links open in the installed app.)
Updates — the app checks for a new version when opened and shows an “Update” button at the bottom when one is live; one tap loads it, no force-quitting needed. The faint version number at the top right of the Today screen always shows which version you're on — tapping it checks for an update immediately, as does Settings → Check for app update.
Old history — switching from another fasting app? Settings → “Import fasting history” accepts pasted rows (day + hours, or start + end times, or this app's own CSV), previews what it found, and adds them as fasts — days that already have a fast are left untouched, and the import can be undone.
Your data — everything is stored only on this device. Export opens the share sheet on iPhone, so the backup can go straight to iCloud Drive (elsewhere it downloads a file); Import restores it. Settings shows how long ago the last backup was — since the phone holds the only copy, an occasional backup is worth it. When it has been more than 30 days, the app says so once (at most monthly) with a bar at the bottom whose “Back up” button opens the share sheet right away. It also asks the system to protect its storage from cleanup (the status is shown below). “Export CSV for Excel” shares two spreadsheet-ready files (semicolon-separated, decimal commas): one row per logged day with status and note, and one row per fast with start, end, and duration.
