SimpleX - the first messaging network without user identifiers of any kind (not even random numbers) - 100% private by design! Security assessments by Trail of Bits: 2022: https://simplex.chat/blog/20221108-simplex-chat-v4.2-security-audit-new-website.html 2024: https://simplex.chat/blog/20241014-simplex-network-v6-1-security-review-better-calls-user-experience.html SimpleX Chat features: - quantum resistant end-to-end encrypted messages, with editing, replies and deletion. - disappearing messages with opt-out per contact/group. - message reactions. - delivery receipts, with opt-out per contact or group. - multiple chat profiles, with hidden profiles. - app access and self-destruct passcodes. - incognito mode - unique to SimpleX Chat. - end-to-end encrypted images and files. - voice messages up to 5 minutes – also end-to-end encrypted. - "live" messages – they update for all recipients as you type them, every few seconds - unique to SimpleX Chat. - connect via one-time invitation links or via long-term public addresses. - secret chat groups - only group members know the group exists and who is the member. - end-to-end encrypted audio and video calls. - connection security code verification, for contacts and group members – to protect from man-in-the-middle attacks (e.g. invitation link substitution). - end-to-end encrypted push notifications (they contain only encrypted meta-data, not the actual content). - encrypted portable chat database - you can transfer your chat contacts and history to another device. - all local files and media are encrypted by default. - animated images and "stickers" (e.g., from GIF and PNG files and from 3rd party keyboards). SimpleX Chat advantages: - privacy of your identity, profile, contacts and metadata: unlike any other existing messaging platform, SimpleX uses no phone numbers or any other identifiers assigned to the users - not even random numbers. This protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers. - complete protection against spam and abuse: as you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address. - full ownership, control and security of your data: SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received. - decentralized proxied peer-to-peer network: you can use SimpleX Chat via your own relay servers and still communicate with people using pre-configured or any other SimpleX relay servers. - fully open-source code. You can connect to anybody you know via link or scan QR code (in the video call or in person) and start sending messages instantly - no emails, phone numbers or passwords needed. Your profile and contacts are only stored in the app on your device - relay servers do not have access to this information. All messages are end-to-end encrypted using open-source quantum resistant double-ratchet protocol; the messages are delivered via relay servers using open-source SimpleX Messaging Protocol.

Verdict

The call

The clearest difference is rating: ZeroFox Alerts at 4.7 against SimpleX Chat's 4.3. SimpleX Chat's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (264 vs 12). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

ZeroFox Alerts holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: SimpleX Chat has 264 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 50% of ZeroFox Alerts's written reviews are positive against 57% of SimpleX Chat's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ZeroFox Alerts ships an update every 2 months, SimpleX Chat every 2 weeks. The most recent releases landed on September 1, 2026 and September 23, 2026 respectively.
