I released a simple app called Secret Agent. It features a set of tools wrapped in a fun secret agent environment.
Tools are: realtime infrared camera filter, compass, geolocator, torch, realtime sensor reading, device & battery info.
FREE version is available on google play at this link: http://play.google.com/store/apps/details?id=net.drkappa.app.secretagent
PRO version (paid) adds a QR Code reader, a secret audio recording tool and a secret video recording tool. PRO version has no ads. It is available here: http://play.google.com/store/apps/de...secretagentpro
Any comment or feedback is welcome, thank you!
