September 3, 2026
Diachronica 1.2.4 gives appearance and guidance a permanent home in Settings. On iPhone and iPad, Settings also opens two wider views of language: the bundled Inner Dialogue globe and the World Languages family tree. They remain distinct from the word stories, keeping the main experience focused. Inner Dialogue now has larger controls, clearer phone instructions, and a direct way back to Diachronica. You can also send general feedback from Settings or report an issue with the story you are reading.
