moss vs Habit Doom
A habit tracker that keeps chosen apps locked until you check off your habits.
Checked 11 November 2026 against Richard Thattil's own pages. We make moss, so we have linked every source below.
What Habit Doom is
Habit Doom is a habit tracker for iPhone and iPad that keeps chosen apps locked by default. You earn screen time by completing habits, and a Bedtime Lock starts at a time you set. An Anti-Cheat Mode asks for a real-time photo with each check-in, checked on the device, and a Hard Mode stops you undoing check-ins, deleting habits or removing apps. A Vacation Mode unlocks everything without breaking streaks. The free tier covers up to 3 habits. Premium is $4.99 a month, $19.99 a year or $29.99 once. It needs iOS 17.6 or later.
What moss is
moss is an iPhone app that comes with a small physical stone. You choose the apps that distract you, tap your phone on the stone, and those apps stay locked until you tap the stone again. People who live together can link their phones to share schedules and put their phones down at the same time, while each person keeps control of their own phone. Locking is free in the app, the stone is a one-time purchase, and the household features are a paid add-on.

- Unlocking means doing something useful first.
- A free tier, and no hardware to buy.
