- notifications on changes/ background sync so that one does not miss the changes
- offline support - the plans are downloaded and can be viewed without connection too
- low maintenance - the access data and settings (if required for a school) are saved, it is not necassary to enter them again and again
- optimized for small screens - the plan list is optimized for small screens (depending on the school, viewing the plan at a small screen is not comfortable)
