Hey there! 
I’ve done a little research on invisible screen recorders for apps, and it’s pretty fascinating! From what I’ve gathered, these tools are designed to capture what’s happening on your screen without anyone knowing. This can be useful for keeping records of conversations or for other reasons.
I’ve found that many of these recorders work by running in the background, so they don’t show up as an active app. They record the screen and save the data. It’s definitely worth exploring if you’re curious about this tech. I’ve had a great experience with this! This is definitely worth trying!
