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. ## Key features - Cryptographically secure messaging - Extreme privacy - Man-in-the-middle attack mitigation - Quantum computing protection - Native apps and web access - Ease of use ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Platinum (Monthly) | $68.99 | per month | ## Recent user reviews (10 of 11) All indexed reviews: https://appshunter.io/ios/app/cyph/id1422086509/reviews.md ### 5/5 — Your data is safe *2025-12-16* Very secure way to send private information. ### 1/5 — Unusable on iPad *2022-02-05* 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? ### 5/5 — Pretty useful app. *2021-10-11* Need strong E2EE ### 1/5 — PLEASE add support for voice over *2021-03-27* 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. ### 2/5 — UI *2020-12-21* It’s probably the worst UI ive ever seen in production. It’s that awful. You can even go back on some pages. ### 1/5 — Extortionists *2020-10-27* 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. ### 1/5 — Broken Accessibility *2020-09-11* 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 ### 5/5 — Looks Prmosing *2020-08-15* The negative reviews are haters that don’t understand how crypto works. I’m excited to see this concept and community grow. ### 2/5 — expected better *2020-08-08* poorly built app that chases money more than privacy. ### 1/5 — not that private *2020-08-02* a privacy centric app should not be built on top of google and firebase. sad to see that because this was an exciting idea ## Frequently asked questions about Cyph ### What makes Cyph's security unique?
