Tundra

An app blocker for people who know they have a problem with their phone — and want something that actually holds.

This is for you if…

  • You've admitted it — you're addicted to your phone, and willpower alone hasn't fixed it.
  • You've tried other blockers and switched them off in seconds.
  • You don't want streaks or points. You want it to be hard.

How it works

Block it

Pick the apps and sites that eat your day. They stop opening.

Breaking it costs you

Want back in? Type a real reason, then wait out a timer. Leave the app and the timer starts over.

And it gets harder

Every break makes the next wait longer. Delete the app to escape and reinstalling locks you out for longer still.

A blocked app showing a padlock and the message: Blocked by Tundra. Stay focused, this app is blocked during your session. A countdown timer reading six seconds remaining, above a note that 100% of past breaks were rated not worth it. A full-screen confirmation asking: Do you really want this? A break means giving up the focus you set out to protect.

Platforms

iPhone — out now macOS — coming Android — coming

Tundra keeps everything on your phone. It has no servers and no analytics — and by Apple's design, it can't even see which apps you picked.

Stop negotiating with yourself.
