DiDi is an app that lets you request a vehicle to take you from one point of the city to another, just like Uber and Cabify. Bear in mind, however, that the app only works in a total of four hundred cities worldwide, so if you are not in one of those specific cities, you won't be able to get a ride with DiDi.
That said in order to use DiDi, all you have to do is set up a registered user account by adding in your real phone number. After creating your account you'll have to indicate your current location and, in a few minutes (seconds if you're lucky) a vehicle will be on its way to pick you up.
As usual with this type of apps, you can make payments from within DiDi itself. You can also write a review for your driver and his vehicle, guaranteeing you a comfortable and pleasant trip around the city every time you ride with DiDi.
DiDi is an interesting transport app, that makes for a great alternative to Uber, Go-Jek, Cabify and other similar apps.
