Promises, with receipts

Make a promise. Send the receipt.

Promisify turns what you said into a receipt the other person holds. They mark it kept or broken. Not you.

Free to start. iPhone: coming soon.

Jonathan promised Sam

I'll drive you to the airport Friday. 6am. No excuses.

If broken
Coffee's on me for a month
Yep, they kept it Nope, they broke it

Only Sam can press these.

Sound familiar?

Promises evaporate.

Said out loud, forgotten by Thursday, argued about on Sunday.

“I never said that.”Every group chat, ever
“I'll do it this weekend. Promise.”Three weekends ago
“You owe me one.” “Owe you what?”Nobody wrote it down

Receipts don't.

How it works

Three taps. One receipt.

The other person doesn't need the app. A link is enough.

1

Write it down

The promise, who it's for, the deadline. Add a penalty if you're feeling brave.

2

Share the receipt

A link or QR code. WhatsApp, iMessage, a sticky note, anywhere.

3

They call it

Kept or broken, marked by the person you promised. Not by you.

Why it sticks

Honest by design.

You can't grade your own homework here.

Top promise keepers, ranked by promises the other person confirmed. Self-promises don't count.

Broken stays broken

Only the recipient can mark a promise kept. Broken ones stay on your record.

Put something on it

Set a penalty. Break the promise and it shows on your receipt until you've paid up.
