Beware. False advertising. My phone has backdoors setup for testing purposes and it doesn't detect it. To expand, it's technically impossible to detect in automated way if your device has been hacked, like the advertisement says. At least not all of them, maybe the trivial vulnerabilities. This app is most likely a scam targeting inexperienced people, to lure then into paid services and offer false sense of security.

App is useless. If you use Magisk hide, repack the Magisk app and make sure your device passes basic SafetyNet attestation it'll work just fine. If you really want to make this app secure then generate local RSA keys, that your friends have to scan (QR code) and periodically check the Hardware-backed SafetyNet. In addition you should improve the UI and overall UX.

This app has false advertising! Stay away from it. After all, I think it is a honeypot. Please search for controversies on this app. This company is related to goverment orgs. and millioners with sketchy past. I suggest you use Signal or even a Telegram but not this! Anyways, it is based on Signal's programming code and alghoritms, so Signal should be better to use. One last thing! This app modifies Signal's encryption alhoritms which means that they might have backdoors installed!
