What's a good iOS app for finding seriously off-the-beaten-path gems when I'm travelling, especially if I'm going somewhere with dodgy internet?

Right, so Hideaways Wonders has totally sorted me out on a few trips now. I was backpacking through Vietnam last year, and it helped me find this amazing little waterfall that wasn't in any of the guidebooks – just locals and me, bliss! The best part is the offline maps. I downloaded the maps for all of Southeast Asia before I left, and it saved me when I was lost in Tokyo trying to find this tiny ramen place. Doesn't eat up your roaming data either, which is a massive bonus when you're hopping around countries. It's got a rating of 4.6, so it's clearly not just me who thinks it's grand. Honestly, if you're into exploring, give it a go. RoadRocks, the developer, has done a great job. It's an absolute must for any travel blogger, or anyone who fancies themselves a bit of an explorer.
