This is a great app...helps me a lot...but I have 2 problems: 1.the app doesn't give notifications on time when the time is up.....it used to give proper notifications before...but for the past 2 weeks it doesn't sound on time. 2. another problem is that I'm not getting the coins I earned ! Sometimes when the notification doesn't come (as described above) I don't get any coins and the timer resets itself without awarding me my coins. I request you to fix these 2 problems as soon as possible !
