Log the set.
Rest. Hit the next one.

Same logging-first DNA, different math. Arnie ships half-point RPE chips inline (not buried in a modal), per-muscle volume tracked against editable MEV / MAV / MRV landmarks, and per-lift e1RM and tonnage updated on every set. The CSV import means migrating in is one paste.

Yes. Unlimited workout logging, the full 1,323-exercise library, half-point RPE, per-lift e1RM, PR detection, CSV import, the anatomical muscle heatmap, the stats screen, the mesocycle screen and CSV sharing are all included with no limits. The free tier shows ads: an interstitial after a finished workout, plus one per day when you come back to the app, one per day on the Stats screen and one per day on the History screen. Arnie Pro removes the ads and adds the active-block card.

Two things: ad-free training, and the active-block card on the mesocycle screen — sessions this week, weeks in a row, your volume against the average of your last four weeks, and how many muscles went past their MRV. That's all. Everything else — the anatomical muscle heatmap, the stats screen, the mesocycle screen itself, per-lift e1RM, PR detection, CSV import and CSV sharing — is free for everyone, with no limits.

Yes. Arnie reads CSV exports from every major lift tracker. Paste it in the import sheet and your sets, PRs, weights, dates, and exercise mappings carry over. The graphs and e1RM curves populate from day one — no empty-state purgatory.

Local-first by default. No account, no email, no cloud sync at all — your training never leaves the device unless you send it yourself. We don't sell training data — there is nothing to sell. Share everything anytime as CSV.

Minimum Effective Volume, Maximum Adaptive Volume, Maximum Recoverable Volume — Renaissance-Periodization-style landmarks for weekly hard sets per muscle. Arnie ships RP-aligned defaults and lets advanced lifters override per muscle so the bar never lights up permanently red.

Fully. Exercise library, your routines, your sessions — all on device. There is no cloud at all: nothing to sync, nothing to wait for. Train in the basement of your gym with zero bars of signal.

Coming. Phase 1 is the iPhone and Android logbook done right. Apple Watch and Wear OS are on the roadmap once the core is rock-solid.

Arnie is the nickname of Arnold Schwarzenegger — the legend who turned bodybuilding from a fringe sport into a discipline anyone could pick up. The app honors that era: iron, sweat, numbers, no fluff. The name is the brief.

Anytime, from your App Store or Google Play account. Lifetime is a one-time payment with no auto-renewal. We don't run dark-pattern cancellation flows.
