Proof: Lifting Log

Proof is a lifting log for people who want a record, not a coach. Most fitness apps tell you what to do. Proof measures what you did, every set, and shows you whether you beat last time.

WHAT IT DOES

• Log a set in two taps. Weight, reps, done.
• Every lift keeps its full history. Nothing is capped or hidden.
• Personal records are detected automatically and sealed the moment you hit them.
• A body map shows which muscles you have trained hard and which you have skipped.
• Patterns surface the honest stuff: your best day, your steadiest day, where you stall.
• A rest timer that runs in the Dynamic Island and on the Lock Screen.

WHAT IT DOES NOT DO

• No subscription. Pay once, keep it forever.
• No account. Nothing to sign up for.
• No cloud. Your training stays on your phone.
• No ads, no feed, no streak guilt.

FREE AND PAID Log as much as you want for free, and the last 30 days are always open. A one-time unlock opens your full history, the body map over time, and every record back to day one.

Built by one person who lifts and wanted an honest instrument, not another coach. Log your lifts. Beat last time.
