Amazon-owned app Wickr has been shut down after it was revealed that it had become an app for drug traffickers.
If you open the Wickr Me encrypted messaging app today, you'll be greeted with a line of red text: “Reconnecting…” and below that, in white text on a black background, the app says “We're having problems connecting to the Wickr Me network. If the problem persists, try restarting your app or contact support.” 
Closing and reopening the app won't help, and there's no point in contacting support because on December 31, 2023, Wickr Me, the free version of Wickr, has completely shut down.
Wickr Me is no longer available for download in the Apple App Store or Google Play Store.
The app stopped accepting new users over a year ago. But today even current users can't talk to each other.
So ends the story of an app that while it never reached the popularity of other encrypted messaging apps like Signal, nor those that later enabled end-to-end encryption for everyone like WhatsApp.
However, it played an important role in the adoption and discussion around secure communications.
