Move your full training history over in under 30 seconds.
Everything the program needs. Nothing it doesn't.
Stone keeps the 5×5 loop fast and hard to mess up, then quietly handles the math, the history, and the edge cases for you.
Progression on autopilot
Add weight each session, and deload after three misses. Or set your own increment and deload logic. Stone tracks the streaks and tells you exactly what to lift next.
Programs your way
Run 5×5, 3×5, 1×5, or 3×8. Tune working sets, reps, and the weight jump for each lift independently.
Swap any lift
Hack squat for cranky knees, leg press when the rack is taken. The substitute inherits your weight, plate math, and PRs.
Easy accessories
Add chin-ups, dips, or curls, and more below your main work. Logged in history, never crowding your progress chart.
History, progress, and PRs
Weekly volume, streaks, inactivity deloads, and PR-aware analytics.
Plates, warmups, timer
See the exact plates to load, follow guided warmup sets, and let the rest timer count between working sets.

Stone vs Stronglifts
An honest comparison.
We built Stone because the official Stronglifts app got expensive and heavy. Here is the real trade-off, so you can pick what fits.
| Feature | Stone | Stronglifts |
|---|---|---|
| One-time price, no subscription Pay once to keep logging after the free trial. No monthly or annual fee — a core reason many lifters switch away from Stronglifts. | Yes $9.99 once | No $59/yr subscription |
| No account or sign-up required Open Stone and start logging. Your data lives on your phone, not behind a login. | Yes | No |
| Works offline, data stays on your device Train with no signal. Stone stores workouts locally on your iPhone. Stronglifts relies on a cloud account for sync. | Yes | Partial Cloud account |
| Free export – CSV & JSON Your history is yours. Export anytime for backup or switching apps — Stone never paywalls your own data. | Yes | No CSV only, requires subscription |
| 5×5 progression, plate math, warmups, rest timer The core barbell loop: auto increments, plate calculator, guided warmups, and rest between working sets. Both apps cover the essentials. | Yes | Yes |
| Cloud sync across devices Pick up on a new phone without a manual transfer. On Stone's roadmap through iCloud sync. Stronglifts offers this today through their account. | Partial Roadmap | Yes |
| Writes workouts to Apple Health Log strength training alongside runs and steps in the Health app. Planned for Stone; Stronglifts supports it now. | Partial Roadmap | Yes |
| Apple Watch app Log sets from your wrist between lifts. Planned for Stone; Stronglifts has a Watch app today. | Partial Roadmap | Yes |
| Multiple programs & large exercise library Programs beyond 5×5 and a big exercise catalog. Stone focuses on 5×5 with per-lift tuning today; a broader library is on the roadmap. | Partial Roadmap | Yes |
| Android app Train on non-iPhone phones. Stone is iPhone-only — a deliberate scope choice. Stronglifts supports Android. | No iPhone only | Yes |
| In-app form videos & coaching Built-in lift demos and coaching content. Stronglifts includes these; Stone focuses on logging and progression, not video coaching. | No | Yes |

Questions
Do I need an account?
No. Stone never asks you to sign up or hand over an email. Open the app and start logging – everything is stored locally on your iPhone.
Is this a subscription?
No, and it never will be. Logging is free for 14 days, then a single $9.99 purchase unlocks it for good. The purchase works with Family Sharing.
Can I import my Stronglifts history?
Yes, for free. Export a Stronglifts CSV, import it in Stone, and your main lifts, variations, and accessory work come across. Imported history never starts your trial.
Can I get my data back out?
Always. Export everything to CSV or JSON whenever you like. Viewing and exporting your own training history is free forever – Stone will never lock you out of it.
Does my data sync to the cloud?
No. Stone is local-first, so your data lives on your device, not on a server. iCloud Documents backup is on the roadmap, but there is no account and no required sync.
What do I need to use Stone?
An iPhone on iOS 17 or later. Stone is iPhone-only and works in pounds or kilograms, whichever you prefer.
