By Vinh Nguyen, from the App StoreDescription by Vinh Nguyen Written by the developer, not by AppBrain. Click to read.
You don't just start a timer. First you write one line — "By the end of this, I will have _". Then you focus. And when the clock runs out, Focus Proof asks the only question that matters: did you?
FOCUS RECEIPTS Every session prints a small, beautiful, collectible receipt — your intention, your focus time, the time of day, and a KEPT or MISSED stamp. Share the ones you're proud of. Keep them all. A missed receipt is still an honest one: you showed up and told the truth.
FOLLOW-THROUGH RATE Not hours logged. Not sessions counted. The percentage of promises you kept — a number no other focus app owns, and the one you'll actually care about. Streaks count days you kept your word, not days you sat there.
BUILT FOR THE PROMISE
• Intention-first: no session starts without one
• An immersive, candle-lit timer that stays out of your way
• Wall-clock accurate — backgrounding never breaks a session
• False starts (under 2 minutes) never count against you
• Finish early when the thing is done — honesty cuts both ways
PRIVATE BY ARCHITECTURE No account. No sign-in. No analytics of our own. No server. Your intentions and receipts never leave your device — we couldn't read them if we wanted to. The free version is supported by ads — never on the question at the end, never on the receipt as it prints. Pro removes them.
FOCUS PROOF PRO — one price, forever The core experience is free and complete: unlimited sessions, the Classic receipt, your follow-through rate, streaks and 7-day stats. Pro removes the ads and adds six more receipt styles (Boarding Pass, Vintage Ticket, Vinyl Label, Polaroid, Blueprint, Telegram), five more accent colours, your live promise on the Lock Screen, in the Dynamic Island and on your Apple Watch, your golden hours, the 30-day trend and how long your sessions really run — for a single one-time purchase. No subscription, ever. An app about keeping promises doesn't rent them back to you.
Make one small promise today. Keep it. Print the proof.
