Google Drive

Google Drive is one of the best Google apps for iPhone users who regularly move between devices. Files, folders, PDFs, and scans can all live here, which makes it really easy to find work documents at home or to make sure you never leave that big project you’re working on behind. 

As we mentioned before, one of Google’s biggest strengths is the free cloud storage it offers. You get 15 GB just for creating an account, which means you’ll be able to store a ton of documents and carry them with you without spending any money.

It also does a good job of handling document scanning and quick uploads from your phone, which makes it more useful on the go than you might expect. If you think of cloud storage as something you need everywhere, not just on Apple devices, Drive will work perfectly for you.
