Using a translation platform
Have you ever thought about using a translation platform to handle app translations?
I can warmly recommend Weblate. It is provided free of charge for FLOSS projects.
Weblate itself is FLOSS too. It is a home for many well known open source projects like F-Droid, OsmAnd, KOReader, DAVx5, Tasks.org, AndrOBD, Minetest, Orbot, Freedombox, and many, many others.
After the initial project setup it is a matter of a push to send new strings to translators and a pull to get the latest translated strings back. That's the manual mode…
I'm asking because I'm interested in translating DecSyncCC and this will greatly improve translators' workflow and onboarding for the project and will surely bring more users to the application. Plus, Weblate handles fastlane too.
