Help with workout app

Hey im interested in making an workout app mainly for Android/pc, ONLY for personal use. So im wondering what tools would be “best” for the tasks i have in mind.

I would like to be able to:

  • insert what workout program im following
  • log (input) things like weight used, notes, RPE.
  • save everything to a database

Thats the main things i have in mind.

I have experience in html/css/js/react

Any tips about how to approach this would be much appreciated!
