In the app after you complete an exercise/workout it will tell you the percentage by which your strength increased.

I noticed that it will give me this stat the first time I do an exercise. Since it is the first data point the app has, it has nothing to compare to, so my strength percentage increases are in the 100s.  

This throws off my overall stats in the dashboard, saying my strength has increased 41% in the past three workouts, when really the app had me start rotating in easy workouts for the first time.

I don’t want the app to calculate my strength percentage gains based off 0 and the first data point in an exercise, but start to calculate it between the 1st and 2nd data points, the 2nd and 3rd data points and so on.

Would love to be able to have the resting ending countdown be modular. 
instead of 3,2,1 being able to have it count from 5 or beep from 10 etc. 

Here we are metric but in a lot of the Gyms the equipment comes from USA and they are slack so lots of the weights are in Pounds. Its a pain to divide by 2.2 or whatever to get to KG so would be great to be able to change on the fly by exercise. Okay so its a small point but maybe other have the same issue?

I think being able to turn on core workouts at the end of your workout (just like you can for cardio) would be awesome. Just like with cardio, you could set it to a 5 min or 10 min additional workout. Currently my workout program has little to no core workouts so I have to do my own exercises outside the app.

One thing that would make the user interface better would be to show the actual weight if the custom weightsIn the barbell weight "calculator" instead of just CUSTOM.

When you get asked if an exercise was hard or you could have done 1-2 reps more and you say it was "very hard", the app auto-lowers the next number of reps.

So far, so good.

The announcer voice, however, doesn't appear to know about about this lowering and still announces you should do the number of reps before the lowering. This is confusing and wrong because the app will still say "4 reps", for example, but the announcer voice will say *3.. 2.. 1.. 5 reps".

Surely is would be advantageous to sync  Dr Muscle with Garmin Connect considering this product is very popular and provides lots of health data that is useful.

I wish that there were more options to set goals. For me. Body weight is too blunt. I would imagine it's the same for most people in this app. It depends on what you're trying to accomplish. For example, strength, bulking, cutting, maintaining, etc. I wish I could set a goal for bench press, chin-ups, 1 km run, broad jump distance, etc. 

Very much interested in improving my VO2 Max. The HIIT work that can be added to a workout is helpful but does not formalize a program dedicated to improving VO2 Max.
