Weight: Analytics & Prediction

Your smart scale has been filling Apple Health with weigh-ins for years — and all you get is a wiggly line. WeighPredictor turns that history into answers. SEE WHERE YOU STAND • Current weight vs your personal reference point, all-time high, all-time low and ideal weight (BMI 22) — in kg and % • Changes over 7 days, 14 days, 1 month, 2 months • Averages per month and per year, with min–max ranges • Month-over-month, quarter-over-quarter and year-over-year progression • Records: lowest and highest ever, longest losing streak, volatility, BMI with every category explained COUNT YOUR YO-YOS WeighPredictor detects every cycle where you lost weight and gained it back — how much, and when. Set your own threshold. PREDICT WHAT'S NEXT Your weight forecast 7 days to 1 year ahead, plus the date you'd reach your goal weight — free, with the linear model. Pro adds two smarter models: • Damped trend — knows every diet slows down • Metabolic — simulates your energy balance day by day from your sex, height and age, converging to a realistic plateau YOUR DATA IS YOURS • Reads weight from Apple Health — works with any smart-scale app (Feelfit, Withings, Renpho…) • Add, correct or delete any weigh-in; optionally sync edits back to Apple Health • Export and import everything as JSON • No account, no ads, no tracking, no servers. Everything stays on your iPhone. The free version is generous and stays that way: the whole dashboard, every chart, yo-yo detection, BMI, the records editor, JSON backup, the full linear forecast and your goal date. One single purchase unlocks the two smart models. No subscription. Not medical advice — just your data, finally legible.
