Re: capturing the whole court, I think we are considering supporting panning of the camera (in addition to syncing). We focus pretty heavily on making sure things work with just a normal phone so it's more accessible to everyone. We are definitely starting bottom up but maybe one day we will get to more high tech hardware.
At my pickups courts we call our own fouls by saying Foul. Perhaps the mic can pickup key words matched the play stopping.
In relation to user experience on first try...I just wanted to test it out for 30 second to see if it's worth keeping. I haven't tested now, will have to wait until I get an hour free later because there are a few roadblocks. - You require email and password registration and to click a verification link. Not too bad - When first launched the app asks you to allow mic permissions by clicking settings. However in Hooper settings on Android there is no mic permissions option. Bad. - You require 5gb free to use the product at all. Understandable given storage is required for video but how about reducing that so users can do like a 30-second test for first use? That way they don't have to spend an hour going through their phone's media to see what they want to keep and what they can delete.
You'd be amazed at how many people (like me lol) have almost full storage on their device most of the time.
Edit: oh....it's not a setting for mic permissions, it's a general permissions setting and if you touch that you can add additional permissions. Based on the text of the popup I hadn't guessed that was the right place to look and I hadn't realised it was possible to add permissions by touching that area of the settings menu.
