In Progress, "info" icon, information might have a math or sanity issue for new members
I'm new to Dr. Muscle and I suspect lack of data to be the root of the problem. I go to preview tomorrow's workout. At the top of the screen showing different exercises, is an "In Progress" with an "i" icon. Clicking the icon displays a pop-over text box. It says I've progress 14108%. Might be more credible to put a sanity check in the software and if unrealistic math results, say "we're establishing your baseline over <insert right number> of workouts" or just leave the paragraph out.

Strength phase fitting into the cycle length
I'm currently on up/low split level 7 and I'm 9 workouts before I level up. Today I started a new cycle (with lower body 7A medium workout). After I was finished, the app told me that starting from my next workout, I'll begin a strength phase, as is supposed to happen every time before going up a level.
This is all fine, but why didn't the strength phase start at the beginning of the new cycle, and why it does not fit into the workout schedule as the strength phase is finished at the middle of the cycle? Is It really necessary that the strength phase is exactly 9 workouts long, or would it be possible to program it to fit into the workout schedule?
As the cycle in my current program is 6 workouts (lower body & upper body all have medium, light, and heavy workouts), perhaps the strength phase could take 6 or 12 workouts? And in PPL level 7 program, the cycle is 9 workouts. On Muscle split program, the cycle is 6 workouts long, etc. You get the picture.

More detailed workout preview
I had a Medium day and started the workout as normal with warmup sets. As I was preparing for the first work set, I noticed that the app gave me such a light weight that it was almost -20% to my previous best. Then I realized that this was marked as a Light (or Easy) set.
I cancelled the light set and the app gave me new weights that had me breaking the old PB, which was just on the money. However, the app also nullified my warmups I had already done. This was slightly annoying, but worse was that I had changed the warmup weights so that I can just add new plates to the bar without the need to srtip old plates. Now my planning was in vein as the weights in the work sets were changed. The same happened in several exercises during the workout.
This happened because in the workout preview, one can only see the reps x weight, but not how it compares to previous PB, or if the workout is scheduled as Easy. So, it would be nice if one could see all data in the workout preview - at least for the upcoming workout.
Another nice improvement would be that the AI would plan ahead the warmup weights to minimize the need to strip plates from the bar. The way I see it, is that it does not make much difference if the warmup set is 6 x 40 kg instead of 7 x 37,5 kg, for example. However it would be much easier to continue adding plates to a 40 kg bar for the next sets.

Send calories to Apple Move ring
I've noticed that even though calories are reported to Apple Health, they are not being added to the Apple move ring.

structuring a workout program based on varying rep ranges
I would like to see a workout program that uses a varying rep ranges in separate workouts: Medium - High - Low rep workouts (rep ranges 6-12 / 10-15 / 3-6, or something similar). And the instructions should be that one is supposed to perform exactly the given amount of reps - unless specifically told to do max reps (as in Reference sets). After the set the user is asked to evaluate the RIR value, as normal. Of course, the user could ask for a reference set (or deload) when he feels like it; just like it currently is.
Irrespective of the rep range, the workouts should be of "average" toughness, and the AI should steadily increase the 1RM of the sets from workout to workout. However, this comparison should not be apples to oranges - e.g. the AI should not compare the 1RM of Low rep workout to the 1RM of High rep workout. Instead, the progress should be separate in all of the rep ranges - some trainees might progress better in High rep range, while some might benefit more from Low reps.
The Reference sets should rotate on a regular basis, in all of the rep ranges; like this:
Medium reps workout: reference set in Incline press and Reverse fly
High reps workout: reference set in Lat pulldown and Dumbbell curl
Low reps workout: reference set in DB shoulder press and Triceps pushdowns
On the next cycle:
Medium reps: reference set in Lat pulldown and Dumbbell curl
High reps: reference set in DB shoulder press and Triceps pushdowns
Low reps: reference set in Incline press and Reverse fly
... And so on.
The deload workouts should be "as necessary", and the whole workout should be deload and not just some exercises.

Build supersets, drop sets, and other techniques in workouts so I can just follow the plan
Things like super sets, drop sets, etc. I know that there are options to insert them into the current workouts, but I don't know which exercies to choose, when, and how often. Yes, I have been working out for over 20 yrs, but I am more of a just follow the plan kinda guy. I hope that makes sense!

Written instructions for exercises
It's good thing that there are video instructions on exercises, but the quality of the videos varies. On some videos there are detailed voice over instructions, but on some videos there is no sound or any instructions whatsoever.
It would be helpful if there would be the key points in every exercise listed with bullet points, and perhaps the most common errors to avoid, also. If you are just looking at the videos with no instructions, you might miss some important points and even excecuting the exercise in dangerous way.
Also, watching the video instructions takes time since some videos are about one minute in length. It would be faster to refresh your memory by just glancing thru the written instructions. This is even more important if you are swapping an exercise in the midst of a workout and you have to search thru the list of exercises.

Plate calculator should plan ahead all the sets
This issue has been addressed before, but I have also a new suggestion.
It would be a very welcame improvement, if the plate calculator could plan the plates ahead, for all of the sets. That way it would be easy to just add plates to the bar, with no need to remove the plates before putting new plates in. And if one uses lighter weight on the last set, the plate calculator could take that into account, so that you could achieve the weight of the last set just by removing the outermost plate(s). There would not be need to strip all of the plates before putting new ones to the bar.
I am experimenting to overcame the problem by using custom set style in barbell excercises and not using a lighter last set on them. It's easy to change weights with dumbbells and pulleys, so I'm using the lighter last set on those excercises.
Come to think about It, It would be a nice addition if one could choose set style based on excercise equipment so that on certain type of excercises the AI would offer one type of excercises/sets and on another type, another workout style. For example, straight sets on heavy compound exercises, and rest pause on others; or same weight on barbell excercises and lighter last set or pyramid sets on others. Would it make it too complicated?
Of course, the user can make the change on individual exercises manually.

Number of reps with "+"
In the workout guidelines, the AI suggests that no matter the target number of reps, I should always be doing as many reps I can muster with good form and common sense. Sometimes I just forget to grind out the extra reps, and just set my mind on achieving the indicated number of reps.
It would be helpful if there was a plus sign after the target number, e.g. '8+' instead of just '8'.
This is a minor thing but should be easy to fix, also, and it would give the app more polished feel.
