One of our favourite Ola/ Uber integrations is with Google Maps - after you've looked up a place on the map, you can quickly call a taxi to get you there. It's a very straightforward feature and one that works pretty well. In the case of Uber, you can directly book the cab through Google Maps without even needing to have Uber app installed on your phone, while with Ola, after you've decided to call the taxi, you have to tap the Open App button to book an Ola cab.
The advantage of booking a cab through the Maps app is that you can see the prices for both Uber and Ola at the same time - and what's more, you can see fare estimates for all classes of cars, so you can see the price for an UberGo, UberX, or UberXL, or for an Ola Micro, Mini, or Prime, all at the same time. This lets you quickly compare fares and find the best option when booking a taxi. This is how it works.
