Four hours of taking viewer questions is the right call. Live is the only place a viewer can ask something and get an answer while it still matters, and that's the reason to stay instead of watching the clip tomorrow. You don't need a special app for this. If you have a real tech team, audience questions can be added to any show: pick the moments when questions go on air, give one producer the job of sorting chat, and have a host answer by name. If your team says it can't be done, you need a different team. That way the hosts aren't reading chat off a phone while results come in, and viewers see that someone on screen actually heard them.
