It works !

They’ve made improvements to the original, so this version of the App works fine now.
Simply size up your capture area and press the Record button. When you’re done, save it in the format you want. Easy!
There is a little bit of loss of quality in the recorded audio, but not enough to worry me.
All in all, it works just fine for the purpose in which it is intended.
