for existing exercise there is photos and video clips but if I create a new exercise for myself the option to add these does not exist.

The app is fine, but it needs a lot more than 4 bodyweight programs. 10 would be minimum.

The number one change I would make for the editor would to have it all happen on one page. Rather then have it go to a page where you choose what exercises to include, and then a page where you decide the order, I would have the basic page where you add exercises, and then when you press the editor button you stay on the same page but can now just drag and drop the exercises, and maybe press a button or Swipe left or right to get rid of an exercise.

Would love to be able to see calories burnt during different time intervals. Last week, month and so on.

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?
