I use Citymapper extensively on trips to cities it covers. It's at its best in London (where, IIRC, the dev team is based): there, it's a life-saver. It's also effective in other first-rank anglophone world cities, such as New York. I've found its coverage can be patchy/incomplete in some cities, presumably because the data sources they aggregate are incomplete or inaccurate: at its worst, it degrades gracefully to the state of an offline maps app with a public transit route-finder. It has been around for some years and they used to integrate with Lyft: I think the idea is to tie into transit pass apps as a way to monetize their service.

I once used it in Berlin (I'm not from Berlin) when there were unexpected line closures/delays. I could explain to the locals what was going on and the best routes to use. That was simply using the app. It had more info than the local staff/info screens.

  I used it in New York, and it also knew about line closures which other apps weren’t aware of. One thing it’s bad at (ironically because it was made in London) is the data model for Tube stations, it seems to think a Tube station is a point, whereas they often sprawl underground over large distances. It doesn’t have much of a concept that you can be walking for 10 minutes to connect between lines, and will make dodgy suggestions on that basis.

    The app certainly does take into account transfer times between lines. If you also require accessible transport it'll further take into account the transfer times by measuring the amount of lifts you need to take.

In London you can buy discounted weekly passes through them now. Working from home for just one day will negate the cost saving though, especially if you’re out in zone 4. I don’t know how they undercut TfL on the price but I presume they’re doing something tricky with redistributing monthly or annual passes.

  They pre-purchase annual oyster cards and sell them back to you at a weekly rate. They recently got Apple Pay which is really useful with the express travel option so you don't need to use touch/face id to tap in. They still have consistent problems with randomly charging you random amounts on top of the weekly cost. It's a normal MasterCard so you can check it on the TfL website, but I've had to work with them a few times to get refunded from random extra charges (usually 0.50 to sometimes 7 quid) which they can't explain why they happen.
