I would give it 5 but....

This is a great app, wonderful concept. My husband and I have been looking for an app like this. I have one concern and a few suggestions. My concern is the alerts dont work, the only time you get an alert about the days events is in the morning. Please fix this, why give the option to have an alert and the alert now work. My suggestion would be implement a way for all users to communicate in the app concerning dates etc, like a chat. Also implement a way to mark events important, and allow them to have different font and sound and possibly an emoji.
