What's a good Android app for recording video using both the front and back cameras at the same time? I want to record my students' reactions during a science experiment.

So, I was looking for a way to record my students' faces while they were doing a particularly explosive science experiment – you know, capture the genuine reactions! My student, Sarah, actually suggested I look for an app that uses both cameras at once. After a bit of searching (and, I admit, a few failed attempts with other apps), I stumbled upon "Dual Camera Sides". It's made by One Music Player. Now, it took me a few days to figure out all the features – why do they hide the settings button there? – but once you get the hang of it, it's surprisingly intuitive. You can record video using both the front and back cameras simultaneously, which is exactly what I needed. It's like having a teaching assistant in your pocket, recording the important stuff! The video quality isn't amazing, mind you, but it's good enough to see the kids' expressions. Even I could figure it out, so that's saying something!
