Let's Workout

The gym tracker that tells you the next weight — with a free AI Coach and no sign-up. Let's Workout is a workout log built for the middle of a set: big buttons, last session's numbers on screen, and a straight answer to "what do I lift today?". Logging works offline, and you never need an account. WHY THIS ONE • It tells you the next weight. Tap the weight on a set and it suggests the load: hit all your reps last time and it says go up; fall short and it says hold. • A free AI Coach, no sign-up. Ask about a lift or your week, get a recap after each workout and a weekly note, and build or improve a routine in seconds. Free within daily limits. Loads come from the app's rules; the AI never picks one on its own. • Genuinely offline. Logging, history, charts, plans and the written guides work with no signal. The AI Coach needs a connection. • Your data, your rules. Free CSV export, import from Hevy or Strong, and one tap to delete your data or your account. FAST WORKOUT LOGGING • Big buttons, a custom number pad and smart weight/reps prefills • Last session's numbers (PREVIOUS) on every set — beat them, tap, done • Log a set by voice: say "Bench press, 80 kilos, 10" and check it before saving • Optional voice coach: spoken rest cues with a 3-2-1 countdown • Warm-up, drop and failure sets, plus a one-tap warm-up generator • Auto rest timer with per-exercise overrides and a live notification • Plate calculator, supersets, reordering, notes and "repeat workout" • Cardio too: log time and distance AI COACH — OPTIONAL AND FREE • Ask the coach: "How is my bench press going?" or "Which lifts are stalled?" • A recap after every workout and a coach's note on your week • Build my program: answer a few questions — quick mode offline, or with AI • Improve a routine and see why each alternative fits when you swap an exercise • Physique check: from a front photo (and a back one if you like), see on your muscle map which muscles could use more training, with weekly set targets you review before anything changes. Separate consent, 18+. SEE YOURSELF GETTING STRONGER • Estimated 1RM, volume and consistency charts per exercise • Personal records tracked automatically, with a trophy the moment you beat one • Muscle heat map, body weight trend and monthly history stats 1,100+ EXERCISES WITH DEMOS AND GUIDES • Animated demos and anatomy diagrams of the muscles worked • A written guide for every exercise: setup, how-to, common mistakes, safety • Search by name, muscle or equipment; add your own exercises WORKOUT PLANS AND HABIT • Ready-made routines: ABC split, hypertrophy, 5Ɨ5 strength, glutes, calisthenics and more • Plan your week by weekday or as a rotation • Weekly goal with streaks, achievements and a weekly recap • Share a workout card or a routine your training partner can open and save APPLE WATCH AND APPLE HEALTH • Start today's routine, log sets and follow the rest ring on Apple Watch; cardio sets record time and distance • Rest timer on the Lock Screen as a Live Activity, with +15s and Skip (iOS 17 or later) • Optional Apple Health sync for finished workouts and body weight Let's Workout is free: logging, library, charts, plans and CSV export. The AI Coach is free within daily limits. Not a medical device: it does not diagnose, treat, cure or prevent any condition. AI Coach answers are general fitness information, not medical advice. Consult a healthcare professional for medical advice. Train. Track. Evolve.
