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.
5x5 workout tracking, without the subscription.
Stone is a local-first 5×5 tracker for iPhone. Your training history lives on your phone, and you pay once instead of renting access forever. Switching from Stronglifts? Import your full history free and pick up where you left off.

Move your full training history over in a few seconds.
Everything the program needs. Nothing it doesn't.
Stone keeps the 5×5 loop fast and hard to mess up, then handles the math and the history so you don't have to think about them.
Programs your way
Pick 5×5, 5×5 Lite, or Madcow 5×5. Madcow ramps to heavy top sets and adds weight weekly when linear progression stalls. 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 adaptive rest timer count down between sets. It scales with the lift, set type, fatigue, and whether you hit your reps. Tap +15 if you need more.

Stone vs Stronglifts.
We built Stone because the official Stronglifts app got expensive and heavy. Here's the real trade-off, so you can pick what fits. Read the full switching guide →
| 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 The core barbell loop: auto increments, plate calculator, and guided warmups. Both apps cover the essentials. | Yes | Yes |
| Adaptive rest timer Both auto-start a countdown after each set and let you add time mid-rest if you're not ready. Stone recalculates every duration from your base rest – longer for deadlifts and missed reps, shorter on ramp sets, more as working sets stack up – with no per-exercise setup. Stronglifts adapts too, but mainly via success vs failure timers (3 min / 5 min defaults) and optional per-lift durations you configure manually. | Yes | Partial |
| Multiple programs & large exercise library Built-in presets: 5×5, 5×5 Lite, and Madcow 5×5 (weekly ramps and top sets for intermediate lifters). Stronglifts still has a bigger program catalog and exercise library. | Partial | Yes |
| Exercise swaps & accessories Swap any main lift for a variation, and keep the same weight, plate math, and PRs. Add optional accessory work per day from Stone's built-in list; logged in history, kept off your strength charts. Stronglifts covers this too, with more exercises currently available. Additional exercises and custom exercises are on Stone's roadmap. | Partial | 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 |
| 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.
