F-Droid

The app at my gym sucks: there is no checklist of what exercises you have done and no tracking of how much weight you used. Plus, for whatever reason, it wants access to my location.

I've found a number of alternatives on F-Droid, but each of the six or so I tried was completely unusable (some seemed unfinished alphas, others are probably too old for my android version).

Is there one app that you use and would recommend?

What I'm looking for is:

• At home: I setup my programs (different ones for different days)
• At the gym: I can select a program, check off the exercises while I do them (the order I do them on depends on where there is fewer people at the gym), and log things like if I managed all the sets/reps, how much weight I used, and how long I exercised for (for things like the tapis roulant).
• Bonus points if I can also track my weight in the same app, and if the app can export/sync the data or produce some kind of graphs/statistics based on it.

Thanks!
