I have used rapido a couple of times if I am not wrong, we are looking at an App with the following implementations:
1 An Auth module (login/register/user management)
2 orders (booking a ride/cancelling a ride/ status of the ride)
3 Payment implementation (online payments/offline payments/ maintaining records)
4 Maps
5 offers
That mostly sums up what you want.
At this price, I'd built you an Android app and handle deployment
If you want an Android, as well as an iOS app, contact me
Furthermore, any sort of admin panel is not included.
