User guide

BBuilder has three tabs on the iPhone (Programmes, Mon alimentation, Courbes) and a workout screen on the Apple Watch. The app's interface is in French; this guide quotes its labels as they appear. Switch tabs by tapping the bottom bar or swiping sideways.

1. Create a program

Programmes tab › "+ un programme", give it a name ("Push", "Legs"…). Open the card, Exercices tab › "+ un exercice": the catalog can be filtered by muscle group and searched by name. If yours is missing, "Il manque le mien ?" adds it.

Tap an exercise in the program to set sets, reps, rest (in 15 s steps) and its order. A long press on a card changes its color or deletes it.

2. Work out with the Apple Watch

Open BBuilder on the iPhone first: it sends your programs to the watch. Until then, the watch shows "j'attends l'iPhone…" (waiting for the iPhone).

  • Tap a program, or "Séance libre" (free workout: your 10 most recent exercises, then the catalog).
  • Tap an exercise: set the kilos with the Digital Crown (2.5 kg steps), the reps with + / −, then "Valider". "Même série" repeats the previous set.
  • Rest counts down (the rest planned for the exercise); "+30 s" extends it, "Je reprends" stops it. The watch taps your wrist at the end.
  • The "⋯" button offers finish and save, pause, or abandon. Finishing sends the workout to the iPhone and saves it to Apple Health if you allowed it.

3. Or with the iPhone

In a program, tap "Je m'entraîne". Tap an exercise to open it: reps and kilos (+ / −, 2.5 kg steps), rest ± 15 s, "Série faite" starts the timer. "+ un autre exercice" adds an exercise outside the program. "J'ai fini" saves the workout; "Laisser tomber" discards it.

4. Notebook and history

A program's Cahier (notebook) tab: your dated notes, and a blue line for each workout done, with its volume. Tap a note to edit or delete it.

Séances tab, or "Toutes mes séances" on the home screen: date, duration, volume and max load of each workout. Open a workout to correct or remove a set, add a note, or delete the workout.

5. Food log

"Mes produits": declare your supplements (name, amount per intake, unit). "+ une prise": product, amount, time. "+ un repas": type, free-text content ("chicken, rice, broccoli"), optional note. The log shows today or yesterday; the "Depuis quand ?" sticky note shows the date you first took each product.

6. Curves, body weight and export

Courbes tab: tap the title to choose the exercise, then "charge max" (heaviest weight lifted) or "volume" (sum of reps × kg). The colored bands show the days you took each supplement.

"Mon poids": enter your morning weight or read it from Apple Health. "Exporter en CSV" creates a file with all your sets, intakes, meals and weights.

7. Settings

The gear at the top of the home screen opens Settings: ten backdrops change the scene behind the window (gym, kitchen, office) — City, Tropical, Mountain, Desert, Surf in Hossegor, Muay Thai in Pattaya, Boxing in New York, MMA in California, CrossFit in Iceland, X Games in Scotland.
