WGHT LOG
Weight tracking, done right
Free · Designed for iPad
Your weight, tracked the medically sound way. Trend, BMI, Apple Health & doctor export. 100% local — no ads, no tracking.
WGHT LOG accompanies your weight journey with a medically sound approach – clear, precise and reduced to the essentials. Built for honest progress tracking, without distraction.
HISTORY & TREND
Interactive weight curve with trend line, from one week to your entire history. Tap the curve to see individual measurements – the real trend stays visible. Search your history by notes, tags and values.
MEDICAL CONTEXT
Tag each entry with markers such as edema, diuretics, menstruation or fasting and add notes – for meaningful documentation. Unusual jumps are flagged before saving.
BMI & STATISTICS
Average, minimum, maximum, change, last 7 and 30 days plus BMI with category at a glance – precisely calculated for any period.
APPLE HEALTH
Save your weight to Apple Health – the app only writes and does not read any Health data. Edits and deletions are reflected there. Optional, fully in your control and deactivatable anytime.
REMINDERS
Discreet weigh-in reminders on any weekday and time – no pressure, just a calm nudge.
DOCTOR EXPORT
Create clean PDF reports with statistics, BMI, tags and notes, or CSV files of your history – ideal for the conversation with your physician.
