The scale lies to you every day. Water, salt, sleep and a late dinner can swing your weight by pounds overnight. One bad morning can feel like failure even when your overall trend is moving in the right direction. OnMyWeigh helps you see the trend underneath the noise. Log your weight in seconds and understand what is actually happening over time. FREE • Fast weigh-in logging with optional time and notes • Full history with edit and delete • Weight charts from 1 week to all time • Goal weight, progress tracking and BMI • Weekly rate of change • Daily water tracking with hydration goals • Weigh-in reminders • Apple Health integration for supported health data • CSV import and export, plus full backup and restore ONMYWEIGH PRO • Smoothed trend line • Projected goal window • Plateau detection and weekly patterns • Milestones and achievements • Custom targets with projected dates • Body measurements • Waist-to-height ratio, shown as a number and a trend — never a risk category • GLP-1 dose tracking, with your weekly rate measured separately on each dose • Blood pressure logging with a trend chart • Eating window tracking • Strength training log with sets, reps, weight and personal records • Shareable PDF progress report DOSES Track GLP-1 injections beside your weight. Log medication, dose, injection site, notes and side effects, and see weight trends by dose phase. OnMyWeigh is a log, not a medication calculator. It does not recommend, schedule, verify or adjust doses. TRAINING Log sets, reps and weight, and keep your heaviest set of each exercise in one place. Pick from a built-in list of lifts or add your own. See your weekly volume, how your bodyweight and your heaviest sets have moved over the same weeks, and a recap of the month. OnMyWeigh records what you lifted. It does not write programmes, prescribe weights, or estimate a one-rep max. BLOOD PRESSURE Log blood pressure readings and see them charted alongside your weight and dose history. OnMyWeigh records readings but does not diagnose, classify or recommend treatment. EATING WINDOW Log when you first and last ate each day. OnMyWeigh works out your eating window, the gap between them, and your average across the days you logged. It does not set targets, prescribe a schedule or tell you when to eat. WATER Track daily water intake and hydration goals. Supported hydration data can be written to Apple Health when you choose. LOGGING TAKES ONE TAP Your weigh-in is the first thing you see and the biggest thing on the screen. It opens showing yesterday's weight, so a normal morning is one tap on plus or minus — or tap the number and type. Nothing is recorded until you do: the starting figure is a hint, never an entry. FIND THINGS WHERE YOU EXPECT THEM Five tabs. Home for logging and today. Trends for charts. Health for everything you track alongside your weight. Training for lifting. History for every log you keep, switchable with a tap. ON IPAD OnMyWeigh is designed for iPad rather than stretched from the phone. Navigation moves to a sidebar, the cards spread across the screen, and the trend chart uses the extra width. PRIVATE BY DESIGN No account. No sign-in. No ads. Your health data is stored on your device unless you choose to share supported information with Apple Health. OnMyWeigh does not use your health data for advertising. IMPORTANT OnMyWeigh is a tracking tool, not a medical device. It does not diagnose, treat or prevent any condition, and nothing in the app is medical advice. BMI and waist-to-height are general population measures. Trend lines and projected dates are statistical estimates, not predictions. Talk to a qualified healthcare professional before making decisions about your weight, medication, blood pressure, hydration or health.
