LOSE THE WEIGHT. KEEP IT OFF.
You know how to lose weight. The hard part is making it last. Boubool takes care of that: helping you keep, while you lose, the habits associated with preserving muscle — protein, strength training, sleep — with or without a GLP-1 medication (tirzepatide, semaglutide…), to prepare for what comes after.
SUBSCRIPTION REQUIRED
Boubool requires a subscription: every feature described below requires Boubool Pro — a yearly subscription (with a 14-day free trial), a monthly subscription, or a one-time lifetime purchase. Prices and terms at the bottom of this page.
THREE LEVERS, ONE RESULT
Three simple rings, every day:
• Eat — protein, fiber, fluids. Build your plate from simple foods, recipes or protein supplements; two rings follow your day and Boubool comments on the meal's balance. No calorie counting: an estimate appears only if you ask for it.
• Move — your steps and the strength sessions that keep your muscle.
• Sleep — a full night, because short sleep wakes up hunger hormones.
The result shows in the Metabolism tab: weight, waist and how they change. One off day breaks nothing — Boubool only takes stock once a week.
GUIDEPOSTS, NOT SCOREBOARDS
Concrete cues ("a palm of protein"), one piece of advice at a time, zero guilt. Boubool always explains why — and refuses forever: no streaks, no calorie counting, no calorie target set by the app.
WITH OR WITHOUT MEDICATION
• On a GLP-1: injection reminders at the interval you set, side-effect and dose-step tracking, preparing for the off-ramp (phases, stabilization, regain alert).
• Type 2 diabetes: blood glucose and HbA1c — never interpreted in place of your doctor.
• Liver (MASLD): ALT, GGT, triglycerides, alcohol log, the −7% milestone.
• Import your blood test as a PDF, read entirely on-device, with manual validation of every value.
APPLE HEALTH AND APPLE WATCH
Weight, sleep, workouts, steps, resting HR and VO2 max are read from Apple Health; what you log is written back wherever Apple Health has a matching type (weight, waist, height, protein, water, blood glucose). The Apple Watch app shows your rings on your wrist. Without a watch, everything that feeds the rings can be entered by hand; steps, VO2 max and resting energy require a watch. The tape-measure lean-mass estimate (US Navy formula) is available for male profiles; for others, waist circumference remains the reference.
YOUR DATA STAYS YOURS
No account, no ads, no server: your data lives on your iPhone and in Apple Health. We could not sell your data even if we wanted to — we never receive it. Only the map background of your routes is loaded from Apple Maps.
WHY "BOUBOOL"? WHY THE β?
The β in our logo refers to the beta cells of the pancreas — the ones GLP-1 medications stimulate. Not a beta version: a finished app with one job, making your loss last.
Boubool is not a medical device, never gives dosing advice and does not replace your doctor.
BOUBOOL PRO SUBSCRIPTION (REQUIRED)
