Great app, easy to use, nice design, motivating statistics and quotes. Thank you developers for this app :). Only one remark from me: if I change the number of repetitions per week of an activity, it changes the whole statistics (also for the previous period). Maybe there could be an option to apply this change only to further period (e.g. when I start an activity twice a week, it becomes a habit and I want to increase it to 3 times a week and I don't want to lose/worsen previous statistics).
