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.

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.
