WAEL is a simple self-hosted weight and exercise log - track your weight and exercise over time with basic metrics and a handy little chart. It can be self-hosted.
NOTE - the Docker setup for this project has been specifically tailored to work on a Raspberry PI, and as such expects to run on arm64 / aarch64 processor architecture. If you want to run on your own rpi, make sure you are running a 64 bit version of your operating system because prisma (the ORM used in this project) requires it.
I guess the Dockerfile can be dissected to figure out how to run it properly?
