Things may seem a bit quiet around Studies, but there is plenty happening behind the scenes. The apps for macOS and iOS continue to advance.
In 2018, the macOS app got support for the new dark mode in Mojave, and can now import data from Anki files (apkg). It will also use text-to-speech technology to read text if audio is not available. This is great for learning foreign languages.
The iOS app also continues to develop, with support for text-to-speech and Anki package import.
