About

Sacoma

The app for your Sacoma scale. Step on and your measurement is in the app — everything your scale can measure, clearly together. WHAT YOU SEE • Your weight, with your history in a chart • Body fat, muscle mass, water percentage, bone mass and more • A short explanation of what each value is and where you stand • With a scale that has handles: a figure showing how fat and muscle are spread across arms, legs and torso FOR THE WHOLE FAMILY Every family member gets their own profile and history. While weighing, the app usually recognises by itself who is on the scale, from the weight. If it gets it wrong, one tap moves the measurement to the right person. BABY MODE You weigh a child by holding it: first yourself, then yourself holding your child. The app works out the difference and tracks the growth. Works on every Sacoma scale. A GOAL AND A REMINDER Set a target weight and follow your progress. A daily reminder skips the days you have already weighed yourself. ANALYSIS REPORT Put your measurement on a single page and share or print it — the same kind of sheet as a body analysis at the gym. APPLE HEALTH Send your weight, body fat, BMI and lean mass to the Health app. The app only writes there and never reads anything from it. SACOMA PLUS Want more from your measurements? With Sacoma Plus you get a health coach that writes a short piece about your measurements every week and every month and answers your questions (written by AI, no medical advice), weekly and monthly insights, fat and muscle per body part over time, the monthly report and sixteen medals for your milestones. Everything the app already does stays free. New in Plus: your Health Score from body, movement and sleep (with Apple Health or Health Connect), a weekly report from the coach every Monday, and a coach who knows what your week looked like. Sacoma Plus costs €2.99 per month or €24.99 per year, is charged to your App Store account and renews automatically until you cancel; you can cancel at any time in your account settings. IN YOUR OWN LANGUAGE Dutch, English, German, French, Italian, Spanish and Polish. YOUR DATA Your measurements live in your own account, on servers inside the European Union. You can export them and close your account in the app — then everything is gone. We never use your data for advertising and never share it. The measurements are intended for wellness and fitness. They are not a medical diagnosis and not suitable as a basis for medical decisions.
