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.
Plus Five

Plus Five is a lift log for people who want to get stronger without making a hobby out of tracking it. Build a workout once, or pick one of nine plans. At the gym, tap Start and tick off your sets. Hit every rep and Plus Five adds 5 lb for next time. Miss a few and it holds the weight until you're ready. That's the whole idea. IN THE WORKOUT • Last time's numbers are already filled in. Tick a set and the rest timer starts. • Warm-up sets worked out for you, and which plates go on each side of the bar. • Supersets, timed holds, bodyweight and assisted lifts all work the way you'd expect. • The rest timer sits on your Lock Screen and in the Dynamic Island. Tick the next set without opening the app. GETTING STRONGER • +5 when you've earned it. When 5 lb jumps stop working for a lift, it switches to adding reps first. • Goals in sets you'd actually do: 225 × 5, not a one-rep max. With an honest guess at how long it'll take. • PRs called out as they happen, and a Momentum page for volume, muscle balance and how often you trained. 147 EXERCISES, NINE PLANS • Every exercise has its own 3D icon and three plain cues. Pick the lifter that looks like you. • Plans for a full gym, dumbbells only, or nothing at all: Full Body, Strength 5×5, Upper/Lower, Push Pull Legs and more. • Add your own exercises. YOURS • No account, no feed, no ads. Your lifts live in your own iCloud and sync between your devices. • Saves workouts to Apple Health, with heart rate from Apple Watch. • An Apple Watch app, Home Screen and Lock Screen widgets, and Siri. • Import your history from a CSV file, and export everything the same way whenever you like. Plus Five uses Apple Health only if you turn it on, and only to save your workouts and estimate the energy they burned.

Verdict
The clearest difference is update cadence: Proof at every 2 days against Plus Five's every 9 days. Proof also leads on device support (4 vs 2) and iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
