Focus is a team sport.

Willpower alone loses to the algorithm. A group chat that knows you caved does not.

Stacks

Lock in with your people.

Start a Stack, share the code, and everyone's distracting apps get blocked for real. It runs on Apple's own Screen Time, so there is no honor system to cheat.

  • 30, 60, 90 minutes, or your own length
  • See who is locked in, live
  • Nudge whoever drifts
Stack screen with buttons to start a 30, 60, or 90 minute Stack and a field to join with a friend's code.
Pacts

A daily limit you keep together.

Agree on a line, like under an hour of Instagram and TikTok a day. Every clean day grows the group streak. The first one over breaks it for everyone, and everyone knows who.

  • A heads-up when you are 5 minutes from the line
  • A calendar of who held and who caved
  • Your phone keeps count privately
Pacts screen showing two pacts with 69 day and 57 day group streaks.
Roasts New in 1.4

Break the pact, hear about it.

When someone caves, the whole pact gets the notification. Hold it to type a roast, or send a voice roast and say it out loud. They get to clap back.

  • Voice roasts up to 30 seconds
  • Roast straight from the notification
  • Only your pact ever sees or hears them
Friends

Streaks worth protecting.

Add friends with a code, or just hold your phones together. See their streaks and who is locked in right now. Days survived together, not hours lost alone.

  • Tap phones to start a Stack
  • Live streaks and focus time
  • Block or report anyone, any time
Friends screen with a friend request from Sam and a list of friends with their streaks.

Your friends see if you held the line. Nothing else.

Which apps you use, and for how long, never leaves your phone. Apple's Screen Time does the counting on your device. PhoneStack only ever learns one thing: whether you stayed under the limit today.

Never sharedWhich apps you picked, or how long you spent in them.
