Secure messaging app Signal is the most important app of 2017. As hacking of text messages is on on the rise; and, as every day there is an article on the web or in the newspaper about some poor soul or politician or celebrity whose texts become a source of embarrassment or confusion, it should be common knowledge that there is a text messaging app that is truly secure and private. Want to text a client about a sensitive legal matter? Tell them to download the Signal app on their phone or tablet. Then, every text you send or receive is totally between the two of you, and no power on earth can read them. You can even tell the app to make the texts disappear after a set time period, or even as soon as they are read. The best part is that Signal can also send regular texts to anyone else, no matter what text app they use. Of course, those texts are in the cloud and can be hacked. Journalists who want to protect their sources, lawyers who deal with confidential information, and anyone who values privacy and security needs to check out this app. Don't wait. Do it now. It is free.
