Description

Cyph is a cryptographically secure messaging and social networking service, providing an extreme level of privacy combined with best-in-class ease of use.

Cyph's patented technology — built by former SpaceX engineers, audited by Cure53, and the basis of research presentations at Black Hat and DEF CON — uniquely allows Cyph to solve the major security and usability limitations of conventional solutions. Only Cyph automatically mitigates man-in-the-middle attacks (with no manual in-person fingerprint verification), offers both native apps and cryptographically secure web access (thanks to WebSign), and as a bonus protects present-day end-to-end encrypted data from future quantum computing attacks.

Unusable on iPad

Shigeru KAWAGUCHI on

It seems that current version even does not go beyond startup logo screen on iPad Pro 11”, while it seems to function on old iPhone 7. Could you please fix?

Pretty useful app.

Need strong E2EE

PLEASE add support for voice over

Reece O'Bryan on

Very much would love to use this app and was even going to purchase the monthly subscription. However, app is not accessible with the built-in screen reader on iPhone called voice over. Please address this and I will immediately make this a five star review and subscribe monthly. This seems like an amazing project from everything that I have read.

UI

Krathen on

It’s probably the worst UI ive ever seen in production. It’s that awful. You can even go back on some pages.

Extortionists

HMCIV on

Downloaded the app and registered when the makers of Cyph emailed to tell me they had already created my account. They apparently decided on my behalf that I should no longer trust Keybase. Now that I have taken control of the account that has my name on it, I will cease to use it. How can I trust cryptographers that introduce themselves by fomenting distrust.

Broken Accessibility

idkayaker on

Could not get past the log-on screen. Edit fields do not respond to Voiceover interaction. Very disappointed to see yet another app not consider access for potential users with access needs in the development process

Looks Prmosing

dcow90 on

The negative reviews are haters that don’t understand how crypto works. I’m excited to see this concept and community grow.

expected better

datznoah on

poorly built app that chases money more than privacy.

not that private

Blakka on

a privacy centric app should not be built on top of google and firebase. sad to see that because this was an exciting idea
