OnMyWeigh
See The Trend, Not The Noise
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
One tap to log. Your weigh-in opens on yesterday's weight — nudge it and you're done. No account, no ads, and it all stays on your device.
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.

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.

Two big changes, and a new way to log your weight.
A NEW WEIGH-IN CARD
Your weigh-in is now 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. Prefer to type? Tap the number. Nothing is recorded until you do — the figure it opens on is a hint, never an entry.
FIND THINGS WHERE YOU EXPECT THEM
Five tabs instead of six that came and went: Home, Trends, Health, Training and History. Health holds everything you track alongside your weight in one scroll. History holds every log — tap Weight, Doses, Fasting, Training or Blood pressure to switch.
TRAINING (Pro)
A new tab for lifting. Log sets, reps and weight from a built-in list of exercises or your own. Personal records, weekly volume, your bodyweight and your heaviest sets on 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.
ALSO NEW
• Waist-to-height ratio — a number and a direction, not a risk category.
• Blood pressure charted over time, alongside the readings themselves.
• Import weigh-ins from a CSV. Merges only — nothing already in the app is changed.
• Eating window tracking. No targets and no schedule.
Nothing you have logged has moved or been lost.
