Ever faced with one of those situations where you need to give out your phone number, but you feel a bit iffy about doing it? RingShuffle is a free app that’s ideal to have on your iPhone for exactly those occasions.

There’s no other way of saying this: Camera Camouflage is sneaky.

It’s a camera app that goes out of its way to avoid looking like a camera. It disguises itself as an incoming phone call. You can even instruct it to activate your phone’s ringtone, so you can pretend to take the call and hold the phone to your ear.

At which point, things get even sneakier.
