When I change my language to German for instance, then back to english, it works while I have the app open, but next time part of the app is still in German. 

The app asks the user to log weight and body fat percentage. Since I don't have a reliable way of measuring my body fat, I have left the box blank. I have dropped weight, but the app says that since I haven't logged my body fat, I might be losing muscle instead of fat. My waist has shrunk so I know that I have lost body fat, but there is no way to tell the app that.

How about adding a box for some body measurements? After all, health wise the waist measurement is more important than fat percentage, and you can easily measure your body measurements, but getting reliable body fat percentage requires some speciality equipment, or you have to pay to get it measured. I have one of thise cheap electric measuring devices, but it is far from reliable. 

Even if you are not trying to lose fat, it still could be useful to record the measurements. 

It would be great to add bowflex max trainer workout.

Having my warmup be a part of the main workout would be beneficial to me in a small, busy gym as sometimes I'll have to do things in a strange order.

Setting up the exercise on the rowing machine. We have two criteria in the application: time and speed. The time is shown either by the machine or separately, but not all rowing machines tell you the speed. Some have speed steps, others have an electronic display and show you the power in watts. Could we have other criteria for measuring effort besides "speed"? And in the current case what does the speed refer to, in kilometers/miles per hour or is it a preset gear of the device?

I would recommend adding something to app that makes this process more transparent and intuitive...maybe a pop-up message the first time you open the app after missing a workout, or not completing a workout. The message could be something like "hey, we noticed that you missed your full body workout on (enter date) and this is your first time back since then. Do you want to do that workout now? " Then if you respond yes there could be a follow-on message like "We noticed that normally you have 48hrs rest between workouts and if you exercise today, you won't have the recommended recovery time. Do you want us to shift (enter whatever workouts are affected) for you do the following dates (enter dates).

Of note, after having done my work out a day later than planned, the app didn't shift things for me. I opened it yesterday (Saturday) planning to do my Friday workout and the app didn't recommend anything. It was telling me to wait until Monday to training despite not having worked out since Thursday. Again, my primary issue with the app is that it isn't an intuitive experience if you miss or don't complete a workout. It might be something useful but it isn't clear to me...maybe it's just me.

The weighted twisting crunch video is different than the animation in the exercise. In my opinion it should be the same to be clear how to do it.

In my last workout, there was only one warmup set for each exercise. Even the first exercise - deadlift - had only one warmup set. This is probably because it was a light workout, but still I feel that one warmup set on the first exercise of the workout is too little, especially when the exercise is a heavy compound exercise. And even if the workout itself might be marked light, the weight might still be heavy. 

Naturally, one can do more, but it still would be good it one could add more warmups on the app at the very least, even if the AI would not offer more warmup sets. Especially the last warmup set might be heavier than the backoff set so taking extra warmups will affect the total load of the workout.  Currently, one can only add work sets but not warmup sets.

In another workout app I have used,  the app tells the user, how many reps (s)he has to complete in order to make a new 1RM in the exercise. That made the trainee to make that extra push in order to make a new record. It might not be obvious, how many reps to target if the weight varies; e.g. if the previous 1 rep record was 7 reps with 85 kilos, how many reps I'll have to manage with 60 kilos?

Currrently, the Dr Muscle app just tells what was my result the last time, but if the weight is dirrerent, that does not necessarily tell much.
