Whether it was not clear in the overview or my own oversight, I was not aware the app had a trial period, with purchase being necessary to retain it for later use. Barely an hour after I began using it, a pop up appeared reminding me of the trial period, in a notification box which was about 4 inches X 4 inches. This reminder said I had 28 days left and suggested I upgrade. I'm sure the intrusive size of the notification 28 days ahead of the dead line can be appreciated. But then it appeared a few times more, reminding me of 28 days. that was earlier today. I logged back on about an hour or two ago, and the dialogue box appeared at start, and this time, would not go away. I had to use task manager to get rid of it, but by this time, I no longer want to deal with the dialogue box as it is sure to pop up again. Overall, it is a good app. However, the intrusion so early in the trial period, and the persistent dialogue box has turned me off this fine product. I'm sorry.
