I literally say in OP that I used to use Excel spreadsheet, and it was absolute shit. Workouts have different metrics (like different weights for different sets, or running which has distance and time), and workouts change, and sometimes you miss days. Making an excel sheet that properly accounts for that stuff is miserable. Plus, none of the amounts are auto-filled. I have to enter 3x10 every day even though I've been doing the same workout for the past 10 days.
I made the app after dealing with spreadsheets for a reason.
