First of all, I want to say that I really do love this app. Its such a great idea, and Im amazed that this is really the only one like it that Ive found. I guess thats because it caters to a pretty small niche of users...musicians who actually practice. The overall concept is solid, and the ideas behind the various features show some real insight into a musicians practice routine, which tells me that the people behind the app have enough experience to create something immensely useful for musicians. But, there are a few things that I feel could use some improvement that would only help make this app even better. First, they really need to address the BMP bug...the app simply does not accurately track BPM. In the practice history section of the app, it seems to always reflect a slower BPM than the one I entered last during my practice routine for that exercise, which keeps me from accurately tracking my progress from day to day. Another thing we really need in this app is the ability to delete and edit daily practice entries. As it stands, you can edit the time, as long as it is still the same day, but you cant edit or move folders once theyre created, or edit practice events from the past. This is basic functionality that should be included in any well designed app, regardless of its primary function. Sometimes, you need to reorganize your folders and excercises...that is basically impossible in its current form. One thing I would like to add to the Iwanna list for this app is a built in metronome...for an app that tracks BPM, that only seems logical, and having the app play back a click track that automatically updates as you adjust the BPM tracker would take one more distraction out of my practice sessions. I really hopwe that the developer will take some of these suggestions into consideration and continue to improve this app. If that happens, I will have no problem giving this app 5 stars.
