Been using the TfL Go: Plan, Pay, Travel app for a couple months now. It’s basically the official transport app for getting around London. Pretty solid if you’re into public transit and need help planning your journeys.
Here’s what you can do: You can look up routes by Tube, bus, train, and even walking or cycling. And it’s got live arrival times for all the different lines, so you can see when your next train or bus is coming. There’s also a step-free mode which is super handy if you need accessible stations.
Look, if you live in or visit London a lot, you’ll probably find this app really useful. It’s not perfect – the UI can be a bit clunky at times – but overall it does the job of helping you get where you need to go on public transport. Worth checking out for sure.
