Loop Habit Tracker alternative
Three Lights vs Loop Habit Tracker
Loop is a genuinely good free, open-source habit tracker — if you're on Android and tracking alone. Three Lights is for the two situations Loop can't cover: using an iPhone or laptop, and building habits together with your partner, family or close friends.

When Loop Habit Tracker is the better choice
If you're Android-only, want zero cost, and value open-source software with no account at all, Loop is hard to beat. It's privacy-friendly, ad-free and well maintained.
When Three Lights is the better choice
- • You switched to iPhone, or your household mixes iPhone and Android.
- • You want your habits synced automatically instead of exported by hand.
- • You want someone else to see your day and cheer you on.
- • You want four sensible habits on day one rather than a blank list.
FAQ
Is there a Loop Habit Tracker for iPhone?
Loop is an open-source Android app and has no official iPhone version. Three Lights runs in any browser and installs on both iOS and Android, so it's a common choice for people moving off Android or sharing habits across both.
Is Three Lights free like Loop?
Loop is entirely free and open source. Three Lights is free for the four wellbeing habits — eat, drink, move, sleep — and Pro is $2.99 per month for custom habits, private Groups and insights.
Does Three Lights work offline?
Yes. It's a progressive web app with offline support, so you can mark your lights without a connection and it syncs when you're back online.
Can I share habits with someone else?
Yes — private Groups in Pro let you invite a partner, family member or close friend by email and see each other's daily lights.
