I really enjoy working on this app although coronavirus literally killed the public transportation in Bay Area :)
I made a few improvements including adding favorite stations (with offline storage), trip planner (had a chance to work on different type of pickers) and pdf schedules (with webview). Updating the react-navigation to v5 wasn't too much of a hassle as well.
The app is currently live on both App Store and Google Play. Github repo here. I'd love to hear your feedback.
I am also looking for a junior dev role for some time with no success. I'd love to chat if anyone is looking for a react native dev. Hit me up!
