Release 7.0 is better
However when the survey was carried out (before this release), the video lagged behind the audio. This was remedied by stopping the camera and restarting. Then it would slowly drift apart again. This only happened over WiFi, it was fine over mobile phone data.
Also, I would expect to be able to view the survey video recordings from within the app, but that is not possible. So now that the survey is done the app is useless to me as I can't refer to it.
1 star removed for each of the above issues.
Now fixed:
If you select About Us, Terms & Conditions or Privacy Policy then the app crashes. Also it accesses whatever is on your clipboard when you start the application.
