Yeeeees!!Citymapper is a godsend for getting around London, especially for figuring out how different bus routes intersect and where walking might be quicker than public transport. Not infallible but I couldn’t live without it. And it’s in about 40 cities across the world now
Wow this blew my mind.I have an app called "What3Words". It basically gives you a 3 word combination depending on wherever you are in the world. This pinpoints your exact location, which you can then communicate to emergency services for instance so that they can locate exactly where you are. The entire world has been divided into 3m x 3m squares and each of those squares has been assigned a 3 word combination so it is very precise. Thankfully haven't needed to use that one, but I think it's a great one to have just in case.
