Hours of rest

A lot easier than paper sheets, easy to track 10/10

Wow

I'm pretty sure no-one uses this app out of choice, however, this is a shocker. I've seen Model-T's that start more reliably than this thing. If you can get it to start without crashing(which is a long shot) then it will probably not let you log in. Once you're in the gui is fine and pretty nifty, but i think i would prefer 40 lines of python the redirect to a browser-in-a-box version of the website.
