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 clearest difference is price: SimpleX Chat at Free against LimeChat's $4.99. SimpleX Chat also leads on rating (4.3 vs 3.1) and ratings volume (268 vs 11). LimeChat's advantage is chart position (#65 vs unranked) and review sentiment (65% vs 56%). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
SimpleX Chat is free to download; LimeChat costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
SimpleX Chat holds the better App Store score, 4.3 against 3.1. That said, the two scores are not equally well evidenced: SimpleX Chat has 268 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 65% of LimeChat's written reviews are positive against 56% of SimpleX Chat's, so the app with the better star average is not the one people write more warmly about.
LimeChat ships an update every 5 weeks, SimpleX Chat every 2 weeks. Both last shipped on October 12, 2026.
