KineTrack vs Weight

KineTrack monitors the acceleration, velocity, jerk and orientation of the user. The first view will show numbers from the iPhone motion sensors. The second view plots all quantities seen on the first view. The last view shows the user's track in two-dimensions.

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.
