Google released Cardboard for iOS to the App Store on Friday, officially bringing the company’s ultra-cheap virtual reality to iPhones.

The free app, which works in conjunction with a DIY mount costing about $20, is available for the iPhone 5 and above, and early reviews report a smooth experience. Google also unveiled at the annual I/O 2015 developer’s conference this week several other new changes to Cardboard, including supporting phones sized up to six inches.

Cardboard, unveiled last year at I/O 2014, was originally designed for Android phones and available on only Google Play — though that didn’t stop iPhone users from coming up with creative ways to use Cardboard with their iPhones.
