A commitment app, not a habit tracker
Swear a promise with a deadline, choose the apps you're willing to lose if you break it, and sign your name to it. Your phone enforces the consequence automatically — even if SwornIn is closed when the deadline passes.
No accounts. No cloud. No social feed. Everything stays on your phone.
How it works
One-time, daily, or weekly — "Read 20 pages, every day before 9 PM."
Pick the apps that get locked if you fail — Apple's own Screen Time picker on iOS, an app list on Android.
Name, date, a finger-drawn signature, and a consequences disclosure you have to actually read and accept.
A deliberate press-and-hold disarms the block before the deadline. Missing it triggers the block automatically — there's no early unlock, not by you, not by us.
The strike ladder
Your chosen apps lock for 24 hours.
48 hours.
No app block — SwornIn itself locks. The paywall is the app, until you pay to reset.
The first reset is $2, then $4, then $8 — each paid reset doubles the next one's price. Your lifetime record of broken promises is permanent — it survives deleting your data, deleting the app, and reinstalling. Paying buys a future, never a past.
The final consequence
You couldn't keep it. So we will.
Fail every reset — all ten — and break your word one more time, and SwornIn makes an offer no other app would dare: tell us where, anywhere in the world, and we'll be there. Not a chatbot. Not a coupon. The person who built this app, keeping the promise you couldn't.
A real, good-faith commitment — see our Terms for the details.
Built for one thing
The block is armed the moment you swear — Apple Screen Time on iOS, a native Android module — not a reminder you can swipe away.
You choose apps through Apple's own picker. SwornIn only ever receives an anonymous token — never the app's name or icon.
Once a block starts, there's no early unlock and no skip. The only thing money buys is a reset after SwornIn itself has locked.
No account, no server, nothing leaves your device. SwornIn doesn't know what you're avoiding — only whether you kept your word.
Make fewer promises. Keep every one.
