The other functions are really cool too though. My kid and I were having fun with the face tracker on it. And it just has a bunch of cool little functions I’ll use later like the lidar and probably coordinates. **Developer response:** Thanks for downloading! ### 5/5 — Amazing! *2026-01-30* This is an incredible utility that does so many different functions and provides a wealth of information. Almost creepy how much information is out there but this utility can alert you to vulnerabilities in addition to its myriad of utilitarian functions. Get it while it’s free! You’ve paid for apps that do much less. **Developer response:** Thanks! It started as a way for me to test some ideas and I thought others might enjoy it as well. ## Frequently asked questions about Just Sensors ### What sensors does Just Sensors display?
