Both apps work seamlessly together. The interface is perfect. The only problem I have is sometimes it switches the 1st and 2nd alert. So my 1st one says it will remind me about the event 30 minutes before and the 2nd alert 1 hour before the event! I paid the $1.99 and I think its completely worth it, but I dont want to know about my appointment 30 minutes before when I set it in the tutorial to 1 hour before. Its an easy fix but I dont want to forget to fix it one time and miss something. The weathercube app is also-you know what forget it! You guys are doing amazing, keep up the good work and please consider fixing my issue if you see it is a problem with others.
