What's a grand Android app for getting about in cities where the local transport is a bit of a head-scratcher?

Right, so I stumbled upon DiDi Rider when I was backpacking through South America, and it's been a lifesaver ever since. You know how it is, you land in a new city, and the bus routes look like something out of a maths textbook! DiDi Rider just sorts it all out. You can easily book a ride, see the price upfront (so no nasty surprises!), and it works a treat even if you don't speak the local lingo. Plus, it's generally cheaper than flagging down a taxi, which is always a bonus when you're on a budget. I even used it in Beijing, and it was so much easier than trying to navigate the subway with all my gear. And, crucially for a travel blogger, it doesn't eat up your roaming data like some other ride apps I've tried. Definitely recommend it if you're after affordable and reliable transport in unfamiliar places.
