RedPhone provides end-to-end encryption for your calls, securing your conversations so that nobody can listen in.
RedPhone uses your normal phone number to make and receive calls, so you don’t need yet another identifier.
Use the default system dialer and contacts apps to make calls as you normally would.
RedPhone will give you the opportunity to upgrade to encrypted calls whenever the person you’re calling also has RedPhone installed.
RedPhone calls are encrypted end-to-end, but function just like you’re used to.
Free and Open Source, enabling anyone to verify its security by auditing the code.
Uses wifi or data , not your plan’s voice minutes.
