All records and graphs are free to use. You don't have to log every day.
Record weight, measurements, medication, tags, and a short note on one screen.
Missed a day? Go back to the date and fill it in later.

Add tags like strength training, cardio, alcohol or side effects with one tap. Pick a tag on the graph to see how those days line up with your numbers.

Period graphs and rolling 7-day and monthly averages show your changes at a glance. The trend carries on even when you skip days.

Turn the weight change for a chosen period into a graph card. Lifestyle tags are never included in the shared image.
