Loop Habit Tracker: best free option (Android) Free
Loop is what every habit app should be: fast check-ins, streaks with a strength score that forgives the occasional miss, flexible schedules (three times a week, not just daily), reminders, and home-screen widgets. It is open source, works fully offline, and asks for no account or payment. There is no catch — it is simply the best free habit tracker on Android.
Best for: Android users, privacy-conscious users. Watch out for: Android only — no iOS version. Official listing via Loop's official site.
Streaks: best for iPhone Paid
Streaks is the Apple-design-award-winning habit app: gorgeous, instant, and integrated with Apple Health so habits like steps or mindfulness minutes can complete themselves automatically. It is a one-time purchase — no subscription — which makes it cheap over time compared with subscription rivals. Widgets and Apple Watch support keep your streaks visible.
Best for: iPhone users who value polish and Health integration. Watch out for: the standard app limits how many habits you track at once, which is arguably a feature — few people sustain more than a handful of new habits anyway. Verify current pricing on the App Store or Streaks' official site.
Habitica: best for motivation through games Freemium
Habitica turns your life into an RPG: completing habits earns experience and gold; skipping them costs you health; friends can form a party and fight bosses together, where your missed habits damage the whole team. The social accountability is the real magic. The core game is free, with a subscription for extras. Details at Habitica's official site.
Best for: gamers and anyone motivated by social accountability. Watch out for: if fantasy RPGs do nothing for you, the interface will feel noisy.
Habitify and TickTick: two strong cross-platform options
Habitify Freemium is the most polished cross-platform tracker, with detailed statistics and sync across iOS, Android, Mac, and web — but the free tier limits the number of habits and locks the best features behind a subscription, so check current limits before building your routine in it. TickTick Freemium is the pragmatic pick if you already use it for tasks: habits live next to your to-do list, so there is one less app to open. See our to-do list apps guide for its task side.
What actually makes habits stick
- Streaks. The don't-break-the-chain effect is real motivation — but pick apps (like Loop) whose streak math forgives planned rest days, or one sick day will demoralize you.
- Reminders. A habit you are not reminded about in week one is a habit that dies in week one. All five apps above include them.
- Widgets. A home-screen widget that shows today's unchecked habits outperforms any notification — it is visible every time you unlock your phone.
- Start stupidly small. Two push-ups, one page, five minutes. The app's job is tracking; your job is making the habit too small to skip.
Pick by persona
- Android user who wants free forever: Loop Habit Tracker.
- iPhone user who wants polish: Streaks.
- Motivated by games and friends: Habitica.
- Wants one app for tasks and habits: TickTick.
- Data nerd on multiple platforms: Habitify (mind the free-tier limits).
Habits also pair well with structure: block time for them using time blocking, and keep the rest of your system lean with the picks in our best productivity tools roundup.

Frequently asked questions
What is the best free habit tracker app?
On Android, Loop Habit Tracker is the best free habit tracker by a wide margin: open source, no ads, no account, with streaks, reminders, widgets, and flexible schedules. On iPhone, Habitica and TickTick both have usable free tiers, though the most polished iOS experience — Streaks — is a small one-time purchase rather than free.
Do habit tracker apps actually work?
They work as a reminder and accountability layer, not as motivation itself. Tracking helps because it makes behavior visible: streaks create a don't-break-the-chain pull, and widgets keep the habit in front of you. Apps fail when the habit is too big — 'exercise daily' dies, 'two push-ups' survives. Shrink the habit, let the app track it.
What happens to my streak if I miss a day?
It depends on the app's philosophy. Strict apps reset the streak to zero, which motivates some people and crushes others. Loop Habit Tracker instead computes a habit strength score that dips rather than resets, and flexible schedules let you plan rest days in advance. If missed days are likely in your life — travel, illness, shift work — choose a forgiving app.
Can I track habits in Notion or a to-do app instead?
Yes. TickTick has habit tracking built in, and a simple Notion database with a checkbox per day works fine — templates for this are widely shared. Dedicated trackers earn their place with streak math, automatic reminders, and home-screen widgets, which a DIY setup lacks. If you already open your to-do app daily, starting there is perfectly reasonable.
