UhuruPhotos is a native Android client for LibrePhotos, written using the latest Android technologies. It is the most feature complete app for LibrePhotos.
It aims to become a full-featured photo album replacement, including features like offline support, backup and sync etc.
LibrePhotos Mobile is the official app, which is at the proof-of-concept stage. It's written in react-native and in the future will share more code with the frontend.
You can download the .apk here. It is technically possible to compile it to also work on iOS, but nobody stepped up to do that yet.
