yu weight tracker, 2026

I wanted a way to track weight without handing the numbers to another company, so yu keeps everything on your phone. There's no account and nothing to sign up for. If you want your data out, you can export it as a CSV or JSON file.

You log one weight a day, with an optional note. The rest is the chart: the last 30, 60 or 90 days or everything you've logged, with a trend line you can switch on.

The code is private, but I'm happy to walk you through it.
