Tons of potential - hamstrung OS 4 capability

If you read the comments section on this developers site, you will
Learn that there is almost a years worth of dissatisfied commentary with no meaningful response.

The app has loads of promise, but in OS 4: it has stability and playback problems, and the flash cannot be disabled (which is a major drawback if you are shooting a sequence at night where a flash is not needed, or worse detrimental. This also wastes battery during long shoots.)

There is also a lack of high definition output.

On the home page of the site there is a note that the devs hope to correct the OS 4 problems by Christmas.

Id wait until these issues have been rectified before downloading.
