This app is great as far as the calendar and task functions. However, it is nearly unbearable to use since it doesn't respect the phone setting to not notify during a call. When it notifies during a phone call using the regular carrier app (not Skype, Hangouts or other app), it buzzes and sends a loud notification that is painful and very disruptive. I sent in a support request 3.5 years ago and they said it shouldn't do that and they were going to "look into it." But they haven't fixed it in any updates and it's been the same on all of the different phones I've had since then, not just an isolated issue on one phone.
