App development is a race. New mysteries and unknown puzzles, new requests from our users, new bugs, and last but not least—the most important driver—new requirements from Google to make the app more secure.
Security was therefore the deciding factor for the current release.
But we have still been able to introduce a number of new features and improvements. Highlights include

• The Polybios table can be modified as desired.
• Custom alphabets can be defined for rotation ciphers.
• Cryptanalysis is supported by frequency calculations.
