We’ve expanded Day One to the Android platform with a solid initial release. It was over a year in development to get all necessary features required to be on par with the iOS app. If you have an Android device, give it a shot.
Our roadmap for updates include: End-to-end encryption support (currently end-to-end journals will not sync to Android), Rich Editor, Tablet / Chromebook support, RTL Languages, UI translations.
Hope you like it!
