You can now grab lemmur from f-droid and the Play store.
If you want to follow lemmur releases/news checkout the repo and/or follow the !lemmur@lemmy.ml community. You can always support the development on Patreon or BuyMeACoffee
PS. We do not flavor our releases: github release tab, fdroid, and play store apks are built from the same source code. Feel free to download lemmur from any place you like.
Can https://github.com/LemmyNet/lemmy-translations be of use? Are there a lot of Lemmur-specific strings?
Here’s an issue for it : https://github.com/krawieck/lemmur/issues/49
Luckily flutter does have i18n libraries, so it’s doable for it to use lemmy-translations as a submodule.
