Otto's Free App Blocker

A free alternative to Roots

At $9.99 a month, Roots is the most expensive monthly subscription of the app blockers on this site, and it runs on iPhone only. What you are paying for is a genuinely original idea. Whether you need it is the question.

Roots' prices as listed on its own pricing page and US App Store page in September 2026: $9.99 a month or $59.99 a year, with a free tier capped at two blocks. There is no lifetime option. An Android version is a waitlist.

Where Roots is the better buy

Roots limits you by how many times you open an app, not just how many minutes you spend in it, and it wraps that in a Balance Score that tries to measure the compulsive quality of your use rather than the quantity. If you are the sort of person who opens Instagram forty times for nine seconds each, that is a better model of your problem than a timer is, and Otto does not do it.

Where Otto is the better fit

Otto counts minutes. If minutes are your problem, you do not need a behavioural score, an iPhone-only app or $59.99 a year to fix it.

This is one of fourteen paid app blockers compared side by side on the alternatives page. There is also a guide to cutting phone use covering the setup no app does for you.

Otto is free, on both stores

No paid tier, no trial that expires, no account. There is a tip jar in the settings and that is the whole business model.
