Yez3 is our app. No other app paid to be included.
Most habit trackers record what you did; few help on the days you don't. Our pick is Yez3: each habit gets a small Minimum for bad days, days off and earned freezes protect your streak, and an AI coach checks in when a habit slips. The other eight record your habits, but none of them combines all four things that keep a habit alive: a smaller version for bad days, a streak that survives a miss, a coach that checks in, and habits next to your tasks.

What makes a habit tracker app actually work?
One thing more than any other: what happens on a bad day. In a study at University College London, Lally and colleagues (2010) found that new habits took a median of 66 days to become automatic, and missing one day didn't materially affect the process. Most people don't quit because they missed a day — they quit because the app made one miss feel like failure. So we compared apps on:
- A smaller version for bad days — so "tired" doesn't mean "skipped".
- Forgiving streaks — days off and freezes instead of a reset to zero.
- Someone who notices — a reminder tells you the time; a coach notices you've slipped three days in a row.
- Habits next to tasks — habits compete with your real to-do list, so they should live in the same plan.
- Fast check-in on every device you use.
The 9 habit tracker apps in detail
1. Yez3 — a habit tracker that plans for bad days
Yez3 is a task tracker, daily planner and AI coach in one. Each habit lives on your daily plan in up to three sizes: a Minimum you'll do even on a bad day ("run 5 minutes"), a realistic 100% and a Maximum. Close your Minimum and the day counts toward your streak. Days off never break it, and freezes earned in strong weeks cover a missed day automatically.
- AI coach that writes first when a key habit is still open near the end of your day — and asks what's in the way.
- Notices patterns. The third "too tired after work" gets a direct suggestion, like moving the habit to the morning.
- Habits and tasks together, critical ones first, with reminders and recurring schedules.
- Brain dump by voice, focus timer, calendar, history charts.
- iPhone, Android and web, 22 languages, works offline on mobile.
2. Loop Habit Tracker — a simple list (Android)
An open-source Android tracker with a "habit strength" score and charts.

5. Habitica — habits as a role-playing game
Habits and to-dos power a pixel-art RPG character; missed habits cost health points.

- Missing: a plan for bad days — misses are punished, which pushes many people to quit.
6. HabitNow — habits and tasks on Android
Habits, recurring tasks and a to-do list with flexible schedules.

How do I choose a habit tracker I'll actually keep using?
- Start with 3–5 habits. Any app becomes a chore with fifteen.
- Check what a missed day does. Skips, freezes or a smaller version keep you going.
- Test the check-in speed. If ticking takes more than a few seconds, you'll stop.
- Decide if you need a nudge. A reminder tells you the time. A coach notices you've skipped three days.
- Give it two weeks. Judge the app after the novelty fades, not on day one.
A tracker is one tool among several: habit stacking tells you when to do the habit, and the tracker tells you whether you did.
Habit tracker apps FAQ
What is the best habit tracker app?
We recommend Yez3, especially if you've struggled to keep habits going: it gives each habit a small Minimum for bad days, protects your streak with days off and earned freezes, keeps habits next to your tasks and has an AI coach that checks in when you slip.
Do habit tracker apps actually work?
Tracking helps. A meta-analysis of 138 studies by Harkin and colleagues (2016) found that monitoring progress promotes goal attainment, especially when progress is recorded. An app works only if you keep opening it, so choose one that's fast and forgiving on bad days.
Is it better to use an app or a paper habit tracker?
Paper is visible on your wall but can't remind you or notice when you slip. An app reminds you, counts streaks and travels in your pocket. Many people start on paper and move to an app when they want reminders and check-ins.
How many habits should I track at once?
Three to five. More than that and the daily check-in becomes a chore, and most of the habits don't stick. Add a new one when an existing habit feels automatic.
Which habit tracker works on both iPhone and Android?
Yez3, Habitify, Habitica and TickTick work on both, and Yez3 also has a web app with the same data. Loop and HabitNow are Android-only, and Streaks is for Apple devices only.
Want a habit tracker that notices when you slip?
Yez3 gives each habit a Minimum for bad days, keeps your streak through days off and has an AI coach that checks in.
