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 2 taps and get back under the bar. The rest timer is there when you want it. • 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: log from your wrist with the Digital Crown, phone stays in the bag. • Live Activities + Dynamic Island: your rest and your next set stay in sight on the Lock Screen, in both modes. • 370+ exercises, supersets (Pro), swap an exercise mid-session. • 52 ready-made workouts, ready to start (12 free): you pick, the app runs it. PROOF YOU'RE MOVING • 48 statistics (14 included, +34 with Pro) built around the only question that matters: are you actually progressing? • Plateau detection: know it's stalling before you lose weeks to it. • Your 1RM projected at 3 and 6 months: 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. • Regularity heatmap, streaks and trophies: your consistency finally shows. • Your session heart rate (Apple Watch): the curve on your recap, your average, your max and your recovery. • 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, Manual mode, Watch, Live Activities, widget, trophies. Pro (7-day free trial, monthly or annual): Lab mode, set-by-set prefill, supersets and session comparison, past sessions, unlimited customization, unlimited stats history, +34 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 No ad trackers. The app works fully 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. Each plan starts with a 7-day free trial; the trial is granted once per Apple Account. 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.

Read full descriptionHide full description
Gomuscu est un carnet de musculation pensé pour la vitesse en pleine séance. Tu lances ton programme, et pour chaque exercice tu vois ce que tu avais fait la dernière fois — poids et répétitions, série par série — au moment où tu remplis aujourd’hui. Pas d’écran séparé à aller ouvrir : c’est sur la même ligne, à côté du champ de saisie. LE CARNET Saisie des répétitions et du poids, série par série. Rappel de la dernière fois sur chaque ligne. Chrono de repos, avec compte à rebours sonore et haptique. Séries dégressives. Note par exercice. L’écran reste allumé pendant la séance. TES PROGRAMMES Crée tes programmes en piochant les exercices par groupe musculaire, donne une couleur à chacun. Le calendrier de l’accueil se colore au fil des séances. APRÈS LA SÉANCE Récap comparé à la dernière fois : écart de tonnage, écart de durée, record perso. Note de séance. TA PROGRESSION Volume total, records, et pour chaque exercice une courbe qui défile : un tap ou le pouce posé lit chaque point. TON PROFIL Séances, tonnage, série de semaines. Mur de douze badges. Ton historique : cartes repliables, filtres par programme et par muscle, choix de la période, édition en ligne. SANS COMPTE Pas d’inscription, pas de mot de passe, rien à créer. Tes séances restent sur ton téléphone. Export et import JSON quand tu veux. CE QUI EST GRATUIT Le carnet, sans limite de séances. Le chrono de repos, jamais restreint. Le récap de fin de séance. Ton historique en entier, aussi loin qu’il remonte. La progression de ton exercice le plus pratiqué, courbe complète comprise. Quatre programmes au total, ceux livrés au départ compris. Les exports JSON et CSV, définitivement. GOMUSCU PRO Ta progression sur tous tes exercices : la courbe de chacun, le volume total, les records. Programmes illimités, et six programmes prêts à l’emploi à ajouter aux tiens. Deux formules : mensuel, ou annuel avec 7 jours d’essai gratuit. Le tarif de ta région s’affiche sur l’écran d’abonnement, dans l’app. L’abonnement se renouvelle automatiquement au même tarif, sauf résiliation au moins 24 h avant la fin de la période en cours. Le paiement est débité sur ton compte Apple à la confirmation de l’achat — pour l’essai gratuit, à sa fin. Résiliation à tout moment dans les réglages de ton compte App Store. La partie non utilisée d’un essai gratuit est perdue si tu souscris avant son terme.
