This is a very innovative app and I long to replace my native video camera with it. However, Precorder is a wee bit buggy. The big button that controls the precording sometimes gets stuck while it expands. Sometimes it stays expanded and wont shrink again back to the normal size. While the precorder button gets stuck/frozen, all the features including the record button are disabled. So I try to close the app by pressing the home button but that doesnt work either. I was about to shut down my iPhone using the home and lock buttons but the app started saving a video.
The big button timer needs to be changed or placed somewhere else because it is too close to the record button. Sometimes I accidentally press record when I want to press the big button to change the precording time.
Finally, the touch focus doesnt work when the app is recording. However, It works when the app isnt recording.
Im using an iPhone 4 with the most current iOS.
