One of the first third-party apps to take advantage of the Mango live-camera feed is CameraFX. However, there’s no trial, and there are some major downsides.
The first disappointment is that there is no free trial, and the app costs $1.49. However, it gets worse from there… the app’s camera feed is extremely laggy. Also, the app seems to be buggy sometimes, since when I first opened it, the video feed was inverted upside down!
It does have plenty of visual effects and features, and you can set the resolution of the pictures and enable/disable the camera flash, but with the really low frame rate, it is tough to use the app. Hopefully an update could fix these issues! But for now, I would not recommend buying this app.
