Working on a project with a colleague who's dropped by? Don't want to give them your Wi-Fi password? InstaWifi generates a QR code for your Wi-Fi, which an Android phone with a QR scanner can use to connect to your network.

Google Translate is also available for iOS, but without the new photo function.
