Every set you grind out deserves to be counted. Basalt Lab is the data discipline of a spreadsheet, built into native iOS: you train, the app keeps score, and your progress becomes visible, session after session. Two modes, depending on how you train: • Manual: log a set in a few taps and get back under the bar. • Lab (Pro): validate with a swipe and the rest rolls into the next set. Your phone fades into the background. YOUR SESSION, WITHOUT FRICTION • Your previous session replayed set by set (Pro): you know exactly what to beat today, and today's load wins when it's heavier. • Apple Watch: dial in reps and weight with the Digital Crown and log the set from your wrist, phone stays in the bag. • Live Activities + Dynamic Island: your session stays in sight on the Lock Screen; in Lab mode, your rest and your next set too. • 500 exercises, supersets (Pro), swap an exercise mid-session. • 113 ready-made workouts, sorted by goal and ready to start (41 free): you pick, the app runs it. PROOF YOU'RE MOVING • 47 statistics (14 included, +33 with Pro) built around the only question that matters: are you actually progressing? • Plateau detection (Pro): know it's stalling before you lose weeks to it. • Your 1RM projected at 3 and 6 months (Pro): see where you're headed, not just where you've been. • Push/Pull ratios, strength radar, an overtraining alert when your volume runs past your average (Pro). • Regularity heatmap, streaks and trophies: your consistency finally shows. • Your session heart rate (Apple Watch): the curve, your average and your max on your recap, plus your recovery with Pro. • Add past sessions to your calendar (Pro): your history stays complete, even when life gets in the way. • A session recap you can share as an image, when you have something to show. WHO IT'S FOR For serious lifters who want to progress without noise. No imposed coach, no childish badges, no social feed: nobody to impress, just you and your numbers. FREE VS PRO Free: unlimited workout journal, 14 statistics over the last 4 weeks, 3 custom sessions and 5 custom exercises (4 exercises per session), Manual mode, Watch, Live Activities, widget, trophies. Pro (monthly or annual, both with a free trial): Lab mode, set-by-set prefill, the other 72 ready-made workouts, supersets and session comparison, past sessions, unlimited customization, unlimited stats history, +33 advanced statistics and the strength radar. THE METHOD, DOCUMENTED The average lifter who tracks their progress does better than 66% of those who don't (Harkin et al., 2016). Same program, app-guided: the sessions get done. Alone, one in two gets skipped (Gavanda et al., 2025). Studies on the methods: not on the app itself. YOUR DATA, YOURS Your workouts, loads and health data are never shared. Once you're signed in, the app works offline: your history lives on your device and belongs to you. Backups hosted in the EU (Paris). You rack the phone, you grab the bar. We keep count. Basalt Lab Pro: auto-renewable subscription. • Monthly: $7.99/month. • Annual: $49.99/year, i.e. $4.17/month. Both plans start with a free trial; one trial per Apple Account, whichever plan you choose. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage your subscription and turn off auto-renew in your Apple Account settings. Prices shown for the U.S. store; they may vary by country.
