SparkyFitness

What it does

Tracks nutrition, exercise, body metrics and health data on infrastructure you control, built for people who want the logging without handing the record to a vendor, and set up for multiple users so a household can share one instance. Self-hosting means backups and updates are your job, and health data is exactly the category where an exposed instance hurts — put it behind authentication and TLS. Not a medical device; don't make treatment decisions from it.

No. It needs a computer.

Can I use SparkyFitness commercially?

The project does not state a clear licence, so commercial use cannot be confirmed here. Check the official page or ask the author before using it at work.
