Ratings and reviews

This app used to work perfectly on my phone. After the August 2022 update it is not working properly. After 8-10 attempts I might get one picture of an intruder (set for 2 failed attempts) and sometimes no pictures at all. Defeats the whole purpose of the app. I have noticed that many negative reviews are after the update date. I wish I never updated or had kept an apk file for the older version. Some apk files won't install or work but it's not working now anyways. I have to uninstall.

I have the free version of this app and given my results i have not been convinced to purchase the full version, let alone keep the free version. After a few days of testing I have determined that this app works less than 10% of the time. I have intentionally and unintentionally entered the incorrect authentication and the app only responded a few times. I have changed the settings and configurations in order to hopefully get better results however it rarely works as advertised.

Is a good app. After reading some reviews, I decided to give it a try, and it worked, but It doesn't cover all cases of stolen phone. For example, what if the person decides to format the phone?? I'm sure that for iPhone, it won't be the case, but for other phones, like androids, it will surely complicated things. The thief can decide to off the phone or format it.
