Frequently asked questions
Where can I download BBuilder?
On the App Store, for free. The watch app installs with the iPhone app.
Do I need an account?
No. On first launch, the iPhone creates a random identifier, kept in your iCloud Keychain, that links your data to your devices. No email, no password.
The watch shows "j'attends l'iPhone…"
That means "waiting for the iPhone". Open BBuilder on the paired iPhone with the watch nearby: it sends your programs and the exercise catalog to the watch. Once the catalog is there, you can also start a free workout ("Séance libre") from the watch.
Can I work out without the watch?
Yes. In a program, "Je m'entraîne" opens the iPhone recorder, with set entry and a rest timer.
Does it work offline?
Yes. Everything is saved on the iPhone first; it is sent to our server as soon as the network is back.
Does BBuilder tell me what to take or how much to lift?
No, never. BBuilder records what you do and shows your curves. It gives no advice, no dosage recommendation, no goal. For any health or nutrition question, ask a professional.
What does BBuilder do with Apple Health?
If you allow it: it saves your strength workouts and body weight to Health, and can read your latest body weight. Without permission, the app works normally. You can change this in Settings › Health › Data Access.
How do I get my data?
Courbes tab › "Exporter en CSV": a file with your sets, supplement intakes, meals and body weight, to open in a spreadsheet.
How do I erase everything?
A workout, note, meal, intake, program or product can be deleted in the app. To erase all your data from our server, write to us (see the privacy policy).
Is the app in English?
Not yet: the interface is in French.
