About Boubool: Weight Loss Habits
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) Using the app requires one of the following purchases (the price in your currency is shown on this App Store page and in the app before you buy): • Boubool Pro — Yearly: one-year auto-renewable subscription, with a 14-day free trial; • Boubool Pro — Monthly: one-month auto-renewable subscription, no trial; • Boubool Pro — Lifetime: one-time purchase, no renewal. Payment is charged to your App Store account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings > your Apple Account > Subscriptions.

What’s new
Version 1.2 · Updated October 11, 2026
The Plate, a new way to log what you eat: place simple foods on your plate, two rings show where your day's protein and fibre stand, and Boubool tells you what it thinks of the meal's balance. Protein supplements (shake, bar, whey), recipes with a photo, your own foods copied from the label, favourites with a long press. Past days can be reviewed and corrected. Nothing to count: a calorie estimate appears only if you ask for it, and "Plate without numbers" hides grams and calories. If your clinician has set an intake for you, you can enter it (off by default). Activity: log the loads of your strength-training sessions if you wish, and your coach comments on each session compared with your previous ones of the same type. Also: milestones when you reach a step in your habits (in the app, and with a notification you can turn off), a coach that never makes the same remark two days in a row, editable past injections, and a review you can leave from Settings.
