FitNotes on iOS. Pretty sure it’s on android also. Not FitNotes 2(another app with the same name), but FitNotes. It’s a one time fee, no subscription or account to set up, super basic (in a good way) and FLEXIBLE. Super easy to create or edit custom exercises and workouts. Can export data to csv. Can track weight, rep, time, RPE, body measurements. Very solid app. Not sponsored lmao just really like the app.

The three variations, pull-up, chin up, and neutral grip pull-ups are all equally good and slightly bias different muscles. I think it’s best to cycle through all of them to be well rounded and you can focus one depending on your goals at that time.

If chin-ups are the only variation you can do for reps right now, then focus on those. They will definitely work the lats and carry over to all variations of pull-ups.

If you’re making content for fun and not trying to make money off it then PeerTube would be the way to go. You can help build the catalog. If you want to make money then unfortunately YouTube is kinda the only way.
