Liftwerk

Read full description

Liftwerk is a minimal gym tracker that strips out everything you don't need. No community, no AI workouts, no AI trainer, no tutorials, no clutter. You open it, create your routine, and log your training. That's it. It works offline-first: your workouts live on your phone from the very first second, and the app opens instantly even if your gym is a basement with no signal. Start as a guest, no account required. If you later want your data on another iPhone, create an account and it syncs on its own. Only if you want to. BUILD ROUTINES THE WAY YOU ACTUALLY TRAIN Create routines with the exercises you really do, and sort them into color-coded groups. Build your own exercise library and find anything in seconds by filtering by muscle, machine or gym. You can also organize your routines by movement pattern. Every exercise adapts to how you lift: warmup sets, top sets, back-offs and drop sets, with the reps and weight you plan. Training one arm or leg at a time? Liftwerk tracks left and right separately. Drag to reorder, leave notes, and set rest per routine or per exercise. START TRAINING HOWEVER YOU WANT Kick off a session from a routine, from your weekly plan, or start a freestyle workout and build it as you go. Mid-session you can add, remove or reorder exercises without losing a thing. The Previous tab shows what you did last time for each exercise so you always know where to push. REST WITHOUT WATCHING THE CLOCK The rest timer tells you when to get back to the bar with a sound. Follow it on your lock screen and in the Dynamic Island without opening the app. You're back under the bar on time without staring at your phone. SEE IF YOU'RE ACTUALLY GETTING STRONGER Track volume, estimated 1RM, and how every exercise and muscle group is trending: by week, by month, or since day one. Beat a mark and Liftwerk flags it right away: a weight PR or a rep PR, spotted on its own. Your full session history is always there with filters to organize them better. WHAT YOU TAKE COUNTS TOO Keep supplements on track with a clear calendar: tap to mark the day, keep your streak going, and set each one up the way you actually take it: daily, a few times a week, or only when you need it. MAKE IT YOURS Pick an accent color, match the app icon to it, and add home screen widgets to jump into a routine or check supplements with one tap. Plan routines across the week so you know what's on each day. Switch between kilos and pounds, use English or Spanish, and run dark mode if you prefer. Finished workouts can sync to Apple Health alongside the rest of your activity. YOUR DATA, YOURS Export a full backup or import one whenever you want. Your training is never trapped. No ads, no tracking, no selling your information. TRY IT, THEN KEEP IT Liftwerk gives you 5 days to try everything. After that, unlock it with a one-time purchase. No subscription, no monthly fee, no features held hostage behind a paywall. Pay once, use it for as long as you train. Liftwerk is designed for people who go to the gym to work out and who value a thoughtful experience, carefully crafted with attention to detail by an individual, not by corporations that use your data or popular apps that charge you a monthly fee.
