flexRep is a strength logger for self-programming lifters — fast in the gym, honest in the analytics, and built natively on the Apple stack. It logs a set in one tap or one sentence, writes every set to Apple Health, runs its analysis and AI on-device with no server, and lets you export everything, free, forever. Not a social network. Not a coaching plan. A serious tool that gets out of the way.
We'll let you know when there's room.
Not a feature count. Four structural commitments the incumbents can’t easily copy, because each is a consequence of building Apple-native and running no server.
Quick Log opens straight to the steppers on every fresh install — no wizard, no profile prompt. A same-as-last-set is one tap; a weight change is two. Or hold the mic and say “two-twenty-five for five.” The set never waits on a heavyweight sheet.
The logging surface →There is no flexRep backend. Your data lives on your device; speech and AI run on-device; sync runs through your own private iCloud. One-time purchase unlocks the on-device app — a subscription is only ever for server-backed sync, never for logging or export.
Where your numbers live →Most lifting apps write a black-box envelope to Apple Health — duration, calories, type. The per-set detail dies on the way. flexRep writes every set, with weight, reps, RPE, and set type carried as HKWorkoutEvent metadata, two ways.
The Apple stack →CSV (two formats), JSON, and a checksummed .flexrep bundle cover every set you’ve ever logged — with no paywall and no missing columns, including bodyweight, added-load, and assist-load. Importers from Strong and Hevy are first-class. No lock-in, by design.
The export, in detail →Pricing and the most-cited complaints are drawn from public sources and reviews, 2026. We’d rather you see the trade-offs than discover them after you’ve moved a year of data.

Competitors move fast — if something here is out of date, tell us and we’ll fix it. The point isn’t to win every row. It’s to win the ones a self-programming lifter actually cares about.
Naming who it isn’t for is how you know who it is for. If any of these is you, a different app will serve you better — and we’d rather say so now.
