Need the synchronization between IOS devices

I really do love this app. I track my grade and remind me for next assignment and exam but The app need to start syncing between IOS devices. I saved all my grade in this app in my iPad Pro and sometimes I dont bring my iPad Pro everywhere with me. As a result whenever i go to my iPhone even though I still have the purchase version of the app I dont have the data information save there so I need to write down again the same grade I did on my table. It really annoying and I hope you guy make it accessible to sync in all IOS devices.
