    Dishonest. Plain and simple. There was no indication this is a free trial to a subscription and I only found out after installing and registering. And despite looking in the app and on the website there is no indication of the cost of this subscription, which in itself seems rather sinister to me.

    Tried on 3 separate occasions over the last 6 months to install the app on two different Android phones. The devices I used for these failed attempted installations were on a fully unlocked Google Pixel 2 XL, and a fully unlocked Google Pixel 3 XL. Both phones have active phone service with "Google Fi". Both phones were running on the newest version of Android during their respective attempts. Today's attempt was on the latest and greatest no-bloatware Android 10 (on both phones) and the app does install, but after confirming your phone number, it asks for "the code," but the 'code' never works (on any of the attempts on any of the devices). In addition, thinking I'm not using the correct 'code' -I've tried the code supplied by the StealthTalk messaging the phone, and I've tried my phone's unlock screen code (because the app doesn't specify what "code' it's wanting you to use, but it doesn't matter, because none of the codes work anyway! - well, I'm tired of trying to find out why the app fails to work. After many useless attempts, my patience is gone - Off to the next app! I hope that the dev team starts performing some QA on each update, to make sure that their work actually functions. Good luck!

    Not understanding why this was found today to be adware by lookout mobile. Lookout has always been pretty good and trustworthy. I'm recommending an uninstall until this is figured out. This could be just a fluke with the algorithm they use but still, it's something to note. I use similar message services that come up clean.

    Fantastic platform and high security. If you are a security expert you can value the data transmission and reception protocols. If you are the sort to like the Mission: Impossible spy type graphics and animations you will love it. All in all I give it 10/10.

    Looked promising but requires a phone number to use. Why? Don't answer that...its absolutely unnecessary. Especially considering soooo many alternatives that are great and don't require a phone number, some not even an email. Like - biocoded, bat messenger, cliq, VIPole, wire, slack, chatwork, crait, session messenger(if it works on your device), clearkeep, zom, secret, librem chat, ghostly, briar, upco, datchat, kik, threema(pay for) ... Come on now, there's really no need for a number.
