BBuilder
Lifting log and supplements
Free · Designed for iPhone. Not verified for macOS.
Log your sets on Apple Watch, your meals and your supplements, and see your curves next to your supplement periods.
BBuilder is a strength training log for iPhone and Apple Watch. It records your workouts, your meals and your supplements, and shows your progress curves next to the periods when you took each supplement. It gives no advice: you see for yourself what changes.
The app's interface is in French.
AT THE GYM, WATCH ON YOUR WRIST
• Start a program on Apple Watch, set the kilos with the Digital Crown, the reps with a tap.
• "Même série" repeats the previous set in one tap.
• Rest counts down on its own and the watch taps your wrist at the end.
• Pause, abandon or finish and save at any time.
OR ON THE IPHONE
• Without the watch, the iPhone recorder does the same: one card per exercise, rest timer.
YOUR PROGRAMS
• Colored cards stuck on the gym window: exercises, target sets, reps and rest.
• A notebook per program for your notes, and your workout history: duration, volume, max load.
• Logged a set wrong? Correct it afterwards.
FOOD LOG
• Free-text meals and supplement intakes in a single daily log.
• No calorie counting, no goals, no comments.
YOUR CURVES
• Max load or volume per exercise, workout after workout.
• A colored band for each period you took a supplement.
• Your daily body weight, entered by hand or read from Apple Health.
YOUR DATA
• No account: a random identifier kept in your iCloud Keychain.
• Workouts and body weight saved to Apple Health if you allow it.
• Full CSV export of your sets, intakes, meals and weights.
Free, no ads, no in-app purchases. Ten backdrops to choose from.
BBuilder is a log, not medical advice: it does not recommend any training, diet or dosage.
