You can recommend something and mean it yet only later realise that you really, really mean it. Usually that’s just because you liked something and you came to like it more. But in this case, I intellectually knew that Citymapper is a very good app for finding bus, train and walking routes – in London. Also New York. Lots of places.

Just not Birmingham where I live. When you launch Citymapper and you’re in a city it doesn’t cover, it tells you. It also says, listen, maybe we will get to your place some day. Let us know that you want it and we’ll see. No promises, but.

I pressed the button adding my vote for Birmingham and I pressed it thinking I’d never hear another word. Did that and went on to test it all out the next time I was in London. It’s very good and I recommended it thoroughly before putting it away and never giving it another thought.

Until this week when the company emailed to say Birmingham is now covered.

So now I’m trying it out everywhere and for everything and I think it’s great. Go read my original praising review on MacNN.com and then go get the app.

That’s of course especially if it covers your city – and the quickest way to find out is download it and try – but also if it covers cities you ever go to.

Plus, it’s free.
