This is an excellent app. I'm reviewing all these as a telecoms engineer used to using the likes of Aston tems and professional test handsets. The one thing missing from this is showing the LTE CQI. That one thing means it's not the best app out there. But, that said, it's very well laid out, the surveying and survey playback is good and if guys you add cqi as its available then it'll be unbeatable

Thank you! I use devices based on Qualcomm chipsets. They never report CQI. Most of reference Google devices are based on Qualcomm. As I know Huawei devices do not show CQI too. This is the reason why I do not use CQI. Pro version of app has no CQI too. Sorry. If you will have questions email me.

This a great app that does it's job perfectly, and is clearly at the top of everything you can find (and I did try many, before settling with this one). Furthermore, the developer was very responsive when I had to contact him, and responded well above and beyond what was to be expected (in both speed and efficiency) in addressing my request. Overall, a great pair (developer/app).

One point because the app gets the location even while closed, every 5 minutes, 24 hours a day. That behavior is not necessary for their use case, they could just use a foreground service while the user performs a monitoring task and don't demand all-the-time location access to even use the app. The developer says they doesn't collect any data, but they are lying, the Android 12 location usage log exposes them.

All collected data are stored and used locally only. Location permission is required not only for location, but also to get cell id (Android requirement). In background Geo location is activated only with active recording. In other cases Geo location is switched off in background. If you do not trust app just uninstall it.
