Two of my Blackberry 10 apps were featured in the BlackBerry 10 App world: SA Events and Folder Music. Both have above 4-star ratings.
SA Events is a BlackBerry 10 app I wrote that displays annual events in South Africa by province, allowing you to plan your outings.
Folder Music is a music player for BlackBerry that allows the user to browser their music by folders, rather than by artist/album/etc.
House4Hack Smart House Access Control app lets you open the gate and front door at the House4Hack hackerspace in Centurion, South Africa, once authorised.
