It is a great and easy to use app. The only problem is if u try book a taxi, drivers love to accept and then cancel it in the middle,so u will wait a lot or in London u will wait forever. My wife saw many drivers pick up and cancel and after waiting ages. We use black cab... That turns out to be cheaper than Bolt and specially uber . It works better in Poland. So if u like easy to use app.Bolt is great. if u want order taxi in London, use black cab. Outside London, if no local taxi, use Bolt.
