Edward Snowden just unveiled one of his newest projects: a security app.
Haven, developed by the Guardian Project and Snowden's Freedom of the Press Foundation, turns any Android phone into a motion, sound, vibration and light detector.
Using either Signal or Tor — both of which use encryption technology — users can monitor the phone's event log remotely and privately. Haven isn't available for iOS devices, but the developers recommend buying an Android burner, which can cost less than $100.
Snowden says the app was designed for "investigative journalists, human rights defenders and people at risk of forced disappearance."
