IRONDOTS allows you to encrypt & decrypt messages into / from a QR code. THE IRONDOTS PRINCIPLE IRONDOTS protects your messages from access by hackers, companies and governments through physical separation and end-to-end encryption. The app can be used completely anonymously (without registration; without providing a phone number or email address). IRONDOTS is based on the "box" model of the open source NaCl Networking and Cryptography Library to transmit messages with a maximum length of 160 characters encrypted into a QR code. COMMUNICATE WITHOUT TRACES IRONDOTS is designed for offline operation, without an internet connection. We have simply not implemented the possibility to communicate with the Internet or other devices. Your secret certificate is stored encrypted with your password on the mobile phone/tablet. All this prevents the collection and misuse of personal information. IRONDOTS is fully compliant with the European Data Protection Act (DPA). BEST ENCRYPTION All messages are always end-to-end encrypted. You can be sure that no one except the intended recipient can read your messages. The key pair is generated and stored encrypted directly on your device. 256-bit long asymmetric keys are used, which are generated using elliptic curve cryptography (Curve25519). This asymmetric key is used to obtain a unique 256-bit symmetric key for each message sent. NO ADS, NO TRACKERS, NO COOKIES IRONDOTS is not financed by advertising and does not collect user data.

Verdict

The call

The clearest difference is price: KNote at Free against IRONDOTS's $99.99. KNote also leads on update cadence (every 10 days vs every 4 months) and iOS requirement (10.0 vs 14.0). IRONDOTS's advantage is in-app purchases (none vs 1). On review sentiment, ads and device support there is nothing between them.
