Weight Tracker with a Progress Chart
Log your weight, see it charted over time, and track how far you are from a goal you set.
Published by Peptade · Weight tracker · Updated September 2026
Weight Tracker keeps one weigh-in per day, in kg or lb, and draws a line through your entries over the range you pick. Logging again on the same day replaces that day's entry.
Set a goal weight and the screen shows how far you have to go, or that you've reached it. The chart also shows how much your weight has changed since the first reading in the range you picked.
Weight values are approximate and meant for general self-tracking. The chart plots what you entered or imported; it isn't a clinical measurement or a diagnosis.
Your weigh-ins, charted
Daily weigh-in
Log today's weight in kg or lb; a second entry that day replaces the first.
Progress chart
A line through your recent weigh-ins, with the range picker right above it.
Goal weight
Set a goal and see how much is left to go, or that you've reached it.
Change over the range
See how much your weight has moved since the first reading in the range you picked.
History you can correct
Browse your recent weigh-ins, or just the past month's, and remove one that's wrong.
Apple Health, both ways
On iOS, weights you log go to Apple Health, and readings from other sources come in for days you haven't logged.
