Three essentials
Not a wish list. Three habits that matter, each with the smallest version you would still call done.
Habit tracking for iPhone
Built for the
days you miss.
Gradually asks for three essential habits, allows one miss a day, and ends the streak only when you miss the same habit twice in a row. A missed Tuesday costs a day. It doesn't cost the month.

The rule
Most trackers count perfect weeks.
This one counts the day after.
Every reset in every other app says the same thing: a slip erases what came before it. Gradually puts a floor under that. The rules are short enough to remember on a bad day — which is the only day they matter.
2 / 3
One miss a day
You can drop one essential habit on any day and keep the others. No reset screen, no warning.
3 / 3
Never twice running
Miss the same habit two days in a row and the streak ends. That is the only way it ends.
Set once, in about four minutes during set-up.
Set-up
Fifteen screens
before your first check-in.
The field guide walks through what a habit is for, how to size it to a real week, and what to do when the week goes wrong. It stops at three habits on purpose.
- 01 What a habit is actually for
- 02 How to cut it to a version a bad week can hold
- 03 What to do on the day it breaks
Inside the app
Small, specific, finished.
Nothing here was added to fill a features page. Each one exists because the daily loop breaks without it.
- A streak per habit
- Each essential habit keeps its own streak and its own record of missed days. One habit's bad week doesn't touch the others.
- Calendar and heatmap
- A month at a glance for every habit. Current streak is free; the full history and heatmap are part of Pro.
- Reminders tied to the habit
- Set a time per habit. The reminder is scheduled only after the habit saves, so a failed edit never leaves a reminder behind.
- Friends, if you want them
- An optional ranking on weekly consistency. Your habits stay yours; the ranking shows the week, not the notes.
66days, median
The evidence
The number most habit apps round down.
A study following 96 people found a median of 66 days before a habit felt automatic. Individual cases ran from 18 to 254 days. Automaticity came from repeating the behaviour in a steady context, not from intensity in the first week.
So this app doesn't promise a new you in 21 days. It is built to keep a habit alive long enough for the effect the research describes to happen at all.
