Signal saw approximately 7.5 million installs globally through the Apple App Store and Google Play store between Jan. 6 and Jan. 10, according to Sensor Tower. That’s 43 times the number from the previous week. It is highest week or even monthly install number for Signal in the app’s history.
Meanwhile Telegram saw 5.6 million downloads globally from Wednesday through Sunday, according to Apptopia.
Signal claims to have “state-of-the-art end-to-end encryption” as part of its service, which prevents messages from being read by those who are not the intended recipient.
