How the Weight Tracker works
Log your weight with a date, and the tracker plots a simple trend line and calculates your total change, average, lowest, and highest recorded weight over time.
Frequently asked questions
How often should I weigh myself?
Many people find once or twice a week, at a consistent time of day, gives a more reliable trend than daily weigh-ins, which fluctuate with water and food.
Is my weight data private?
Yes — entries are stored only in your browser and never uploaded anywhere.
