## What is Proof?

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.

## Version history (last 5 releases)

### 2.3 — 2026-10-22

Proof 2.3, What's New
Balance. A third tab on Progress that puts the week your body had next to the week your log had: steps, active minutes, sleep and lifting on one grid, with one word on top. In balance, short on rest, easing off, off the plan. Steps, exercise minutes, sleep and resting heart rate are read from Apple Health on your phone and never sent anywhere. Over time Proof learns what your sleep and your steps do to your lifting, and says so in counts once it has the sessions to back it up.

Body. Compare now shows what you trained more in green and less in blue on every skin.

Single arm and single leg. A switch in the lift menu for lifts you do one side at a time.

Import. Lift names from Strong and Hevy keep your own wording. Imported history keeps its own milestones, but time with Proof starts at your first workout filed here.

Fixes. The just-logged chip no longer turns into a white card. The Next up card on Today keeps its Start button in place on every phone size. Session insights lift rows open with a slide and come back the same way.

### 2.2.5 — 2026-10-21

Apple Health. Turn it on in Settings and every workout you file is saved to Health as strength training, with its real start and end. Your past workouts go in once. Watch workouts are never counted twice.

Notes on a lift. Open the lift menu in the logger and add a note: one that shows every time, one for today only. A lift with a note gets a small icon by its name. Tap it to read the note.

Setup. The first screen asks how you want to start: build a routine, use your own, or import from Strong or Hevy. Each goal says what it measures. If you have your own routine, setup is three steps.

Fixes. The pick-a-day card on your first Today scrolls inside the card and the Start button stays put. The setup header no longer lets content show through

### 2.2.4 — 2026-10-20

A new first run. Five quick questions, one a screen, and Proof builds your week. Today then asks which day you want first.
Progress, Body and History open as you earn them: two with your first workout, the third with your second.
First steps: six stamps for your first week, in Milestones.
When one workout earns several things, you tap through them one by one.
Close-out now asks how hard it was, 1 to 5, and your session insights read it.

### 2.2.3 — 2026-10-18

What’s New

Milestones. Your workouts now earn badges: workout counts, weeks in a row, sets logged, your first plates on a lift, and the total you’ve moved, measured in cars, elephants, and a 747. Find them under History.

Session insights. Progress now opens with a plain read of your latest workout, in the words of your goal: what moved, what held, and the three numbers behind it.

Drop sets. Swipe the set type in the logger to drop. Proof takes the weight down for you, set after set, with no rest timer in between.

Your week, recapped. A note drops in on Today with last week’s workouts, records, and badges. Tap it for the full story.

Also: edit the routine from the logger, warm-ups show as a simple W, one Default look for everyone, Body’s new layout on every skin, and a fix for records that were being called too early.

### 2.2.2 — 2026-10-17

Easier to read: new type and larger text. Two new looks, Midnight brass and Mono, plus a warmer Dark. Smarter lift insights that notice one more rep, a comeback after a rough session, and lighter weight for more reps. Widgets and more.
