You can use it for pretty much anything. You can track your exercise, your eating habits, really anything at all. It has basic statistics, it can export your data, it is completely locally hosted and the interface is clean and easy to use.

It's one of those apps that you probably didn't even think that you might need until you see it and use it.

I have no affiliation with the developer, but I thought other people might really enjoy this as well. So I am sharing here.
