Disclosure: Reset is ours, and it is listed first. It gets the same four fields as every other app, including its drawbacks.

Short answer

For iPhone, our pick is Reset — Screen Time blocking where a friend holds the key, free with no subscription. For free delays instead of locks, ScreenZen.

Freedom’s strength is reach: one blocklist across phones, tablets and computers, with scheduled sessions. Its listing offers a 7-day free trial of Premium, then a subscription.

If your problem is mostly your phone, you may not need cross-device blocking — and several iPhone apps block just as hard for free.

Switch to Reset if

  • Your phone is the problem, not your laptop
  • You don’t want another subscription
  • You keep ending your own sessions

Stay with Freedom if

  • You block websites on your computer too
  • You like scheduled recurring sessions everywhere
  • You use its focus sounds

The apps in detail

1

Reset

Ours
Reset on iPhone — the apps it keeps closed
Reset on iPhone
Best for
People who keep tapping through their own limits and want a friend to hold the key
Highlights
  • Real blocking built on Apple’s Screen Time
  • The friend key: only a friend’s code ends a locked block early
  • SOS for the urge and a 22-exercise Boredom Gym
  • No account, no server, no ads
Pricing
Free, with no subscription and no in-app purchases
Watch out
iPhone only, on iOS 18 or later — no Android, no Mac and no browser extension. The friend key works best if you actually have someone to hold it; without one, a block ends only through the emergency unlock, which makes you wait.

Who can end the block?

Every blocker has an off switch. With Freedom, Opal or Screen Time, the person tempted is usually the person holding it.

Reset hands the switch to a friend: they scan your phone or tap a link, and only their code ends a locked block early. Calls, Messages and Maps stay open.
