New iOS user here, coming from Android. I am looking for a simple gym log aka workout tracker. My requirements are:

• Add exercises with a custom name.
• Log multiple sets per exercise. Log per set: weight, and number of repetitions
• Create workouts based on your exercises
• Ability to start the aforementioned workout, and track the exercises/weights/reps per workout
• Data stored on device only
• Available in Germany

On android I used GymRoutines https://f-droid.org/packages/com.noahjutz.gymroutines/), which provides exactly the functionalities that I need. On iOS, I simply cannot find an app that either requires an account or is freemium with a very limited free plan.

I would really appreciate some recommendations. Also feel free to roast me for expecting FOSS apps or free apps on iOS.
