Very useful app!
Journaling your practise time has been preached by many great musicians and teachers for years. This app is much more convenient and far more powerful than a paper journal. The BPM sliders are a bit difficult to use, but hopefully that will be remedied soon. I love this app and recomended it to all practising musicians.
