1. Taxi & transport — FREE NOW is Europe's #1

Now offers an integrated service across 9+ European countries and 150 cities, spanning taxis, e-scooters, e-bikes, and rental cars. Since it connects you with officially licensed taxi drivers, it's legally safe with no issues around local regulations.
- Countries served: Germany, UK, Spain, France, Italy, Portugal, Ireland, Poland, Austria, Hungary, Romania, and more
- Taxi types: standard taxi, premium taxi, electric taxi, airport limousine
- Advance booking: book up to 7 days ahead, timed to airport pickup or hotel checkout
