Review summary

Users appreciate Cryptool for its strong privacy focus, user-friendly interface, and effective encryption without producing long strings. Security enhancements are valued, and the tool is highly recommended. However, multiple users mention difficulty decoding messages, lack of an onboarding guide for new users, occasional slowness, and some dissatisfaction with interface updates. Overall, it is regarded as a great cryptography app with room for improvement in usability and performance.

Pros

Easy to understand and use with a well-designed UI.
Effective cryptography tool that does not generate unnecessarily long strings.
Focuses on privacy and security features, including improvements like bypassing Android Clipboard for enhanced security.
Highly recommended by users for its functionality and design.

Cons

Difficult to read and decode received messages within the app.
Lack of guidance or tutorial for first-time users.
Somewhat slow performance and specific issues with algorithms like RC4.
Interface changes that some users did not prefer compared to previous versions.
