When you use Android and iOS devices alongside each other, the cloud is your friend. The more data you keep online rather than in local storage, the more you'll be able to access on any device. So if an app asks you where you want to save a backup or store data, choose the cloud option if it's available. Many apps now default to cloud storage anyway, but if you do get the option, then take it. In addition, don't bother paying for multiple cloud-storage systems—aim to stick with either Google Drive or iCloud.
