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.
