GeForce NOW, NVIDIA's cloud streaming service for games, is available starting today for iOS Safari in a beta release.

NVIDIA has managed to get around the notorious Apple Store restrictions by using a web app. You will be required to use a gamepad due to 'hardware limitations', apparently, so it's not currently possible to use a mouse and keyboard for example.
