Please backup your data before upgrading to iOS 10!
iOS 10 looks to be a nice update for users with compatible devices. Based on my own limited testing, my apps seem to be fine, with noticeable speed improvements on my iPhone 6s and iPad Air. 🙂
Before you go ahead and update your entire operating system(!), clearly you need to back up your data. You can use iTunes backups for this, e.g, to iCloud, but I wouldn’t rely on this completely.
Each of my apps support backups – see this post for full details. And remember to export your backup off your device!
Then sit back, upgrade and enjoy iOS 10!
