Google Play Books allows you to upload your own PDFs and EPUBs to their cloud for free, making it a powerful "all-in-one" reader.

Once the transaction is complete, the book is officially tied to your Google account. It won't automatically download to your phone to save space, so you'll need to "claim" it in the app. Open the on your iPhone. Tap on the Library tab at the bottom.

Since the app doesn't allow transactions, you must go to the source using a mobile or desktop browser (Safari, Chrome, or Firefox). Open your browser and go to the Google Play Store . Sign in with the you use for your books.

Google often runs different sales or offers "Play Points" that can be redeemed for discounts.
