Gym Book gives you a training plan, tracks every set and every meal, tells you which muscles are recovered and shows your progress. Works offline, syncs across your phone, watch, Mac and PC.
iPhone·Android·Wear OS·Mac·Windows
From the first plan to your hundredth workout - and every meal in between - Gym Book does the bookkeeping so you can focus on lifting.
Answer a few questions and pick from 20+ signature programs, or with Pro have AI build one for your goal, days and equipment. Edit any day yourself, change it by chatting with the AI coach (Pro), or import one you already follow.
Last time's weights and reps are already filled in. Tap to finish a set, the rest timer starts on its own, and warm-up sets and the plates to load are worked out for you.
A muscle map shows how rested each muscle group is, so you know which day is ready to go - and get a heads-up before you train something still recovering.
Log meals (scan barcodes on Android) and hit your protein. Calorie targets follow your aim, and the goal weight shows the date you'll get there.
Volume, sets, estimated 1RM and personal records per exercise, a training calendar, full history, body weight and progress photos, and a suggested weight for next time.
Every exercise has a picture, a demonstration video, step-by-step instructions and the muscles it works. Filter by muscle or equipment, or add your own.
See friends' workouts, like and comment, and race each other in challenges: most workouts, sets, volume or active days, a lift, or days on your food targets.
Every workout earns XP. Climb leagues, see how your big lifts compare with famous ones, and keep your streaks alive.
Your account backs up your training, so you can pick up where you left off on your phone, Mac or PC - even mid-workout. On a Wear OS watch, run a workout or follow your phone's, tick sets and see your rest and heart rate.
Every set you log feeds a recovery estimate for each muscle group. The Workout tab shows whether your next day is good to go, and Gym Book warns you before you hit a muscle that still needs time.
How recovery works →
Short on time, missing equipment or want more arms? Tell the coach and it changes the plan. Every week it looks at how training went and suggests what to change.
Meet the AI coach →
Calories and macros set from your aim and pace, a food log, and your goal weight with the date you'll reach it - updated with every meal.
Weekly volume, sets per muscle, estimated one-rep max and personal records for every exercise. When you hit all your reps, Gym Book suggests the weight to try next time.
One account, every screen. Your workout follows you mid-set, and everything keeps working offline and syncs when you're back online.
Everything you need to plan, log and track is free, with no ads. Gym Book Pro adds the AI features.
The AI features are free for every account right now. If that changes, the app shows Gym Book Pro's price and asks before charging anything.
Free on Android, Wear OS, iPhone, iPad, Mac and Windows.
Yes. Logging, plans, recovery, progress, nutrition and sync are all free, with no ads. Gym Book Pro adds the AI features (AI plans, the AI coach, AI plan import, physique checks and AI food estimates from a description or a photo), free for everyone for now.
Yes, a free one: sign up with your email (or Google on Android, iPhone, iPad and Windows) when you first open the app. It backs up your training and syncs it between your devices. Everything is also kept on the device, so once you're signed in the app works without a connection.
Android phones, Wear OS watches, iPhone and iPad, Macs and Windows PCs. Your data syncs between all of them. The watch app can run a workout of its own or follow the one on your phone.
Search the food database, pick something you've eaten before or type in calories and macros. On Android you can also scan a barcode. With Gym Book Pro you can describe a meal or take a photo of it and let AI estimate it. You can plan meals ahead and tick them off when you eat them.
When you ask for a plan, chat with the coach, import a plan, estimate a meal or check your physique, and for the weekly plan review and the coach's looks at your food and workouts, the details it needs (like your goal, experience and the plan) are sent to OpenAI to write the answer. Your name and email are never sent. See the privacy policy for exactly what each feature sends.
Yes. Import your workout history from a Strong or Hevy CSV export, free. With Gym Book Pro you can also import any plan from text, a link, a photo or a PDF.
Yes. Pick kg or lbs any time in Profile › App settings › Units, separately for the weights you lift and your body weight.
Delete your account from the Profile tab and everything synced to it is removed from our server straight away. You can also request it by email without the app.
