★★★★★Sam McGuire· Jan 4, 2020
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.

Look, I don't mind paying, but tell me that upfront. All of a sudden us users run into information that we have a paid subscription?? 😂 Really? Wth? Super fishy. I'm only giving you 5 stars because I respect developers and their hard work. But from the business side of things omg be more transparent wth.

This is an excellent app I love it is Right Superior but the only thing when you forget the codes I don't understand the code setup in order to get it activated other than that I love this app

Can we see online mentions/reviews and public audits?

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 Stealth Talk messaging the phone, and I've tried my phones 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 a good app to use on Messenger texting with people who aren't a contact on the phone. No way to message to just an unknown person about a one-time issue
★☆☆☆☆Zyxl345· Apr 3, 2021
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.
