Based on the Ankulua scripts of FGO-Lua, I’ve created a free Android app that can automatically farm quests and open lottery boxes.
The app is open-sourced on GitHub
It does NOT need root to run, but requires Android 7 at minimum.
It uses image recognition to detect the current state of the game and can handle much more than simple auto clicker scripts.
See the Troubleshooting Guide if you face any problems.
Most of the heavy work for the project was done by the FGO-Lua team, I just removed the dependency on AnkuLua by writing functions that do similar things myself. As a result, there is NO TIME LIMIT in the app. Also, the settings can be configured using a UI.
Here is a preview of the app:
