Yeah, it seems that I didn't make the note functionality intuitive. They supposed to be for general use, like: "I get distracted around 12". Should I explain it better and leave them for general purpose or make a description view for every task ? I will definitely add repeat functionality as well as possibility to plan entire week in advance.
The app should recognize the last task finish time, I implemented the functionality. Could you confirm that it doesn't work on your phone ? If it doesn't, could you tell me the android version you use ? I would test it against. If it comes to picker, I don't like it. Although, I understand that some people prefer it, so I might add option to choose between standard way of entering time and picker. Thanks for your feedback.
