BLINDSPOT

BLINDSPOT is an instant messaging app with a very interesting feature: all the messages you send are absolutely anonymous. That said, the other person needs to have this app installed as well.

The app has almost no settings or options. You can only choose a contact and send a message. The other person, then, receives a message but doesn't know it's from you. It's important to mention, you can only send these messages to your contacts, so there's no sending anonymous messages to strangers.

BLINDSPOT is a pretty unique and interesting messaging app. However, it's more of a complement than a full alternative to other messaging apps, like WhatsApp, LINE, or Facebook Messenger.
