So, what’s the best app? Download Citymapper for survival. Add WhatPub? for soul. And Too Good To Go for your wallet. That’s the holy trinity. You don’t need a tourist pass. You need a charged battery and a sense of adventure.
One last thing: talk to people. Your app might say “turn left,” but a retired cabbie might say “mate, the Queen’s swans are blocking the river.” Trust the human. The app is your tool. The city is your playground. Now go. Mind the gap.
