Unusable
Loads slowly and there is so much lag that Im often not sure if the app is even working or completely frozen up. Nothing else is anywhere this slow on my iPad (Air 2). A calendar app shouldnt be very demanding on resources, so I dont get why it runs like garbage. At this point, its pretty much useless on my iPad, so I usually just do all my calendar work on my ancient Android Phone (Nexus 5), where it runs perfectly.
