The app isn't hard to use but why would you not put the "ARM" and "DISARM" button on the first page!? As soon as the app opens people want to immediately arm or disarm their system. Instead you have to wait for the app to load and then you have to swipe to the last page which is the most important and most used page in the entire app. Alot of lag and startup time could be eliminated by simply putting two large "ARM" & "DISARM" buttons on the very first page as the first thing you see.
