### 5/5 — Good Lyft Driver, bad app

*2021-12-20, version 1.1*

The creator of the app was a pretty good Lyft driver, which is how I heard about this game. App doesn't work at all and feels very unprofessional. I was immediately off put by the UI. Dude, if you read this, please remake the app with different developers, these ones did a horrible job.
