Loop Habit Tracker
Free, open-source Android habit tracker with detailed graphs, no account, no ads, and nothing leaves the device.
The privacy-first pick for anyone who wants habit data to stay fully local, the same instinct behind not handing over more data than a tool needs.
Loop Habit Tracker is the pick for anyone who wants habit tracking without handing anything over. There's no account to create, no cloud sync, no ads, and no data leaving your device at all, everything is stored locally on the phone. For a category of app that's inherently tracking personal behaviour data, that's a genuinely different privacy posture than most alternatives.
It's fully open source under the GPLv3 licence, so the code is publicly auditable rather than a black box you're trusting on faith. It's also completely free with nothing held back behind a paywall, no premium tier trying to upsell you, which is unusual and worth noting specifically.
Where it earns its keep beyond the privacy angle is the analytics. It generates detailed graphs and statistics on your habit consistency over time, genuinely useful for seeing patterns (which days you consistently skip, how your streak trends over months) rather than just a simple checkmark-per-day view.
It's Android and F-Droid only, so it's not an option if you're on iPhone, worth knowing upfront. For anyone on Android who wants a serious, private, ad-free habit tracker with real analytics and doesn't care about gamification or social features, this is a strong, no-cost pick with over 5 million downloads and a 4.8-star rating behind it.
Frequently Asked Questions
Does Loop Habit Tracker actually collect no data at all?
Correct, everything is stored locally on your device, there's no account, no cloud sync, and no data sent anywhere. It's genuinely designed around that privacy-first principle, not just marketed that way.
Is Loop Habit Tracker really completely free?
Yes, it's free and open source (GPLv3 licence) with no premium tier, no ads, and no in-app purchases. Nothing is held back behind a paywall.
Does Loop Habit Tracker work on iPhone?
No, it's Android and F-Droid only. If you're on iOS, Streaks or Habitica are the alternatives on this list.
What makes the graphs and stats in Loop Habit Tracker useful?
Beyond a simple daily checkmark, it generates detailed consistency graphs and statistics over time, letting you see patterns like which days you tend to skip or how your streak trends over weeks and months, more analytical depth than a basic streak counter.
Is Loop Habit Tracker actually open source, and does that matter?
Yes, the full source code is published under the GPLv3 licence and publicly auditable. For a habit tracker specifically, that matters if you want independent verification that the no-data-collection claim is actually true in the code, not just stated in a privacy policy.
