Hello Gowin, I was actually trying to add all public transportation of the country to make an app for offline navigaiton for each province on Android as it exists only for Manila (and Cebu is handling with ggl maps). Google maps was too expensive or restriction so it couldn't work. I tried OSM but it's too complicated to my taste so it's taking too long...

If you want to help and/or know someone that could, just let me know :)
