Weight and doses
Progress draws a smooth trend through your weigh-ins and puts your dose steps underneath, on the same timeline. You see when each dose started, and the day you crossed the line at 200 pounds.
Doses
Your next dose waits on Home with its day, time and medicine. Log it, skip it or log it late, and the schedule keeps up. Reminders arrive on your dose days.

Medication level
Onederland estimates how much medicine is in your body from your logged doses and each medicine's published half-life, in whole percent. 100% is your average once you've been on the same dose for a few weeks.
Food and protein
Describe a meal or take a photo, and Onederland estimates its calories and protein. Or scan a barcode, search what you've eaten before or log it by hand. Today's protein is always on Home.

The name
Onederland is what people call weighing under 200 pounds: the day the scale starts with a 1. The app draws that line on your chart and marks the day you cross it, or the line at 100 kg if you weigh in kilograms. Your own goal gets its moment too, wherever it is.
Every log got you here, one day at a time.

One clear thing first on each screen, quiet colors, no streak shaming and no noise.
Food is fuel, not a test. Weight moves both ways. A missed dose is logistics, never a failure.
We estimate, we say so, and we cite our sources. We never tell you which dose to take.
Your health data is stored on your iPhone by default, and we never sell it.
Free and Plus
Dose tracking, the medication level estimate, Apple Health and reports cost nothing. Onederland Plus adds AI food logging and 3D body compare.
