How did you get this through App Store review? My understanding is Apple tends to be pretty strict about apps that rely on reverse-engineered private APIs.
App Review didn't object to that. There are various apps on the App Store today that rely on reverse engineering, such as unified messaging apps, alternative rideshare price comparison apps, and driver-side rideshare aggregators.
I've been using this for a few months at least on both android and ios and have not been banned or locked out of any of my linked accounts but obviously that can change at any moment
That's a valid concern but I think it's unlikely. No one's account has been locked for using this app. Rideshare companies take a large cut of the ride fare, so locking user accounts for using third-party apps is against their incentives. It's more likely that they would try to prevent this app from working, rather than targeting users of the app.
That can work for two apps but it's tedious once there are three or more. You'd also need to swipe back and forth between apps to find the corresponding prices for each ride type (Wait & Save, Standard, Comfort, etc.), whereas this app groups together the prices for each ride type across providers.
Great example of something that on-device general agents should be able to do: Operate the apps to get prices and summarize prices.
