Show HN: Traindown Transponder – Simply record your training data

Hey folks! Creator here.

I am trying to build out this app with two goals: 1) Users have full control of their data 2) The input is as fast as it can be digitally (try to match pen/paper).

For more information on the open source markup language used in the app, here is the website: https://www.traindown.com

I would love any feedback you may have. Thanks!
