Olvid vs WannaCall

Olvid is the first private instant messaging application for everyone. What is a "private" messenger? It's a messenger: - That does not push new contacts on you. You are in control: you choose who you want to discuss with. Olvid offers several ways to invite other Olvid users, either face-to-face or remotely. - That does not require any personal data. Olvid won't ask for your phone number, for your email. Unlike your previous messenger, Olvid will never request access to your address book. - On which you will never receive unsolicited messages or messages from an unknown source. - Where all exchanges benefit from the same security and privacy as a real-world discussion behind closed doors. Olvid offers end-to-end encryption and end-to-end authentication by default, always, for everything you send or receive. Olvid guarantees you safe spaces, immune to external aggression, which isolate you from the digital noise and violence of other social networks. Create groups with your family, friends and key collaborators. No spam, no advertising. You finally regain full control over your communications. Olvid has been designed to be the best place to exchange on subjects that matter, with those who matter to you. Olvid - Technology ------------------ At the heart of Olvid, a 'cryptographic engine' coming from several years of research allows to mathematically prove the authenticity, the integrity, and the confidentiality of your communications.

WannaCall tells you when your friends are available for a call — for example while they are driving — so you can catch up at exactly the right moment. Long drive ahead? WannaCall automatically notices that you are on the road and lets your friends know you are available. They see your status, give you a call, and the kilometers fly by. HOW IT WORKS • Automatic driving detection: WannaCall recognises your car via Bluetooth and on-device motion detection and sets your status to "available". • Friends see your status in real time and know it is a good moment to call. • Call with one tap, straight from the app. • Prefer manual control? Toggle your availability yourself at any time. FIND YOUR FRIENDS • Add friends by name or phone number. • Or let WannaCall suggest friends from your contacts — privately: only irreversible hashes are compared, your address book never leaves your phone. PRIVACY FIRST • Your location, motion and Bluetooth data are processed entirely on your device and are never uploaded. • Only your availability status is shared, and only with friends you have explicitly added. • No ads, no tracking, no selling of data. Sign in with Apple, Google or your phone number and never miss a good moment to call again.
