This looks like a beginners project to learn how to start writing iOS apps. It's not ready to be a paid app.Problems include:- The resolution dropdown has a lot of unneccesary info that does nothing but distract from selecting a resolution. e.g. "Y'CbCr -uyvy, 1280 x 720" it looks quit cryptic. Why not just "1280 x 720"?- the drop down for sample rate and bit depth is unlabelled. All items that are 16-but repeat "Linear PCM, 16 bit little-endian signed integer" and all 24 bit item are preceeded by "Linear PCM, 24 bit little-endian floating point". This is overly redundant and just makes it harder to see what you are selecting. Stereo is always Left and Right so no need to say "Stereo (LR) every time. For example, instead of "Linear PCM, 24 bit little-endian signed integer, 44100 Hz, Stereo (LR)" could be "24 bit 44100 Hz Stereo PCM".- Preset dropdown repeats "AVCaptureSessionPreset" at the beginning of every preset. That does nothing to identify the preset so it is unnecessary.- The use of one button for "Start Record /Stop and save" is a bad idea. There is no feedback when you are actually recording so you don't know if it started. IF you press the button again to try to make sure you have started, you are actually stopping it. Most of the time it ends up saving nothing. I maaged to get it to record one time but since there is no feedback, I'm not sure what I did differently. It would be much better to have used a standard recorder style with a record button that displayed a blinking red light when it is in record mode. Then a separate stop button that is only enable when it is not stopped.Since this app is a one trick pony - record video, it should at a minimum support pausing (using a separate pause button and feedback when it is engaged).
