Levelweight: Trend & Forecast

Levelweight turns your Apple Health weight, steps, and active energy into a smoothed line, a rate of change, and a realistic forecast range — never a single date. No food logging, ever. Most weight apps show you noisy day-to-day numbers or make you log every meal. Levelweight does neither. It reads your existing Apple Health data and shows what actually matters: where your weight is really heading, not today's scale reading, and a forecast expressed as a range you can trust. WHY A SMOOTHED LINE, NOT A NUMBER Daily weight bounces with water, sodium, and hormones. Levelweight applies smoothing to your raw weigh-ins so you see the real signal, with your raw entries still shown alongside it — never hidden. Missing a day or two doesn't break the picture. ACTIVITY-AWARE, NOT CALORIE-COUNTED Unlike step-informed calorie apps that require days of food logging, Levelweight explains a shift in your rate of change using your steps and active energy — automatically, from Health data you already have. Zero food logging, ever. A FORECAST YOU CAN ACTUALLY TRUST Other apps predict a single target date, which is almost always wrong. Levelweight's forecast is a range, built from an approximation of the published NIH/Kevin Hall Body Weight Planner methodology, not the outdated 3,500-calorie rule. A CALM GLP-1 LOG On a GLP-1 medication like semaglutide? Log your injection date, dose, and site, and see it overlaid on your progress chart. No streaks, no badges, no celebratory notifications — just a clear picture, because clinicians have specifically warned against gamifying this. GENUINELY FREE CORE Your smoothed line, your forecast range, Apple Health sync, and full CSV export of both raw and processed data are free, from day one — not a trial, not a teaser. Levelweight+ (monthly or annual) unlocks the GLP-1 log, the activity overlay, seasonal and year-over-year views once you have enough history, Home Screen and Lock Screen widgets, an Apple Watch complication, and multiple goal tracks. YOUR DATA STAYS YOURS Apple Health is the source of truth for your weight history, so a reinstall never loses your progress. No account, no login, no server — everything runs on your device. Levelweight is not a calorie counter, not a food diary, and not a gamified weight-loss app. It's a calm, honest read on where you're really heading.
