Definitely open to contributions, but I'll note that the barebones nature is mostly by design. I'm happy to take any usability improvements (of which I can imagine many!), but I don't want to introduce dependencies on design/component frameworks or even CSS libraries.

Generally, all the content for a day's lifts should fit on a single small mobile phone screen to make it dead simple to record a lift and then get to the next one.

Feel free to email me (address is on website in profile) or open an issue on the repo with ideas/requests, happy to chat more.
