I downloaded Freebird rides to help subsidize my Uber rides to local restaurants and bars on my Moto Z2 Force I picked up from SD. It actually works really well. It only requires that you register the same credit card that you use for the Uber app and the one you use to pay your restaurant bill. The app will show you what a restaurant is willing to pay to help ease the financial pain of getting there. The app utilizes the Uber platform and then hails the vehicle. Everything is seamless and you don't ever have to open the Uber app. On the return, brands such as Don Julio will subsidize a portion of the fare in many cases. I found the app great when you want to go have some fun with friends but don't want to designate a driver.
You also earn points on your rides which convert to various rewards. Currently 5,000 points earns $10 in cashback. I received an email that says if you take two rides this weekend, they'll put 1000 points in your account as a bonus. Of course there are referral bonuses but I'm not posting my code because of the forum rules.
Have a great weekend and be safe out there.
