Your last session, on screen while you're doing the next one. Alspr shows the weight, reps and RPE you hit last time inline on every set, so adding weight or reps is a decision rather than a memory test. A PROGRESSION ENGINE THAT PAYS ATTENTION - Warm-up and ramp-up sets don't affect your progression. Only your working sets count. - One weak session doesn't reset your numbers. Targets are anchored across your recent sessions, not just the last one. - Log RPE and the targets respond: a set that was a grind holds the weight instead of adding to it. - Alspr learns the weight jump you actually use on each exercise instead of assuming a fixed increment. - The same lift on two different days is one continuous progression, not two separate histories. - Start a new exercise and Alspr estimates a working weight from a similar lift you already do. ON YOUR WRIST - Apple Watch app: start, log and finish a workout without your phone. - Your weight and rep targets on the watch, not just set logging. - A complication for your watch face. - Live Activities: current exercise, set and rest timer without opening the app. - Workouts sync to Apple Health, with heart rate from your watch. TRACK WHAT CHANGED - PR detection across weight, reps and volume. - Estimated 1RM curves over 30 days, 90 days, 6 months or all time. - Calendar view of every session with volume, sets and time. - Effort rating on each workout. TOOLS - Plate calculator. - 1RM calculator. - Rest timer and a built-in workout timer. - Program templates, free for everyone. Pick one and it becomes your split. - 260+ exercises, plus custom, bodyweight and timed movements. - Share a workout card, or put your stats over a photo or video. Works in the gym with no signal. Everything logs offline and syncs when you're back. FREE TO START Unlimited workouts, routines and custom splits, with 90 days of history. Program templates, the plate and 1RM calculators, the rest timer, the Apple Watch app and Health sync are all free.

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.
