19. FourSquare - Free (Android & IOS)
Whether I'm back in my native Dublin or in the middle of Budapest, FourSquare is one the best apps I have ever encountered. It's been around for a while now and I after downloading it I can really see why it's so darn popular. It helps you decipher the good restaurant from the bad, what's worth checking out in the city (whenever you may be). Also, you'll find the WiFi code for just about anywhere in the comments of the place. It's a thumbs up from me!
18. VSCO Cam - Free (Android & IOS)
VSCOCam is gradually growing in competition with Instagram. With it's slick modern design and fantastic editing features, it can be seen as the hipster alternative to Instagram. Fret not, it offers sharing options with fellow social media platforms (Facebook, Twitter, Instagram etc.) but it has it's own photo-sharing platform called The Grid. The Grid can be rather encapsulating with it's gorgeous array of stunning photos from fellow shutterbugs, great for inspiration and upping your travel pics game.

Challenge your friends or play with fellow online strangers!

It's hard not to get swept up in Eastern European countries where you don't know the money, but you've heard it's cheap. A beer is 1,200 Hungarian Forints. Bad Inflation means it must it's cheap right? NOPE. That's about €3.80, which is expensive for a beer in Hungary. So watch your pennies!
13. TravelSafe Pro - Free (Android & IOS)

Snapseed is free and awesome. It's another photo-editing but it's features are borderline professional. It may take a little while to figure out how to get the most from it, but it'll turn your photos of the Eiffel Tower into photography masterpieces.
9. The Cleaner - Free (Android)
Better than most memory whipper apps, The Cleaner does exactly what it says on the tin. Not only does it save your battery from draining, but it will let you know when your phone's memory is getting full. Plus it's super satisfying to watch the memory being cleaned away.

A great app if you what to keep an eye on your alcohol intake. Yes yes you're on holiday, but once you see you've been drinking an average of 6 pints, 2 shots and a cocktail a day it's a nice reminder than maybe you should give your temple a day off.

Think ahead. There's nothing more annoying then someone stumbling in at 4am and can't find their way to their bed. DO NOT BE THAT PERSON. It'll also help you find all your stuff when you have an early flight to wherever but you don't want to make your dormmates up.

It gives you the world at your fingertips!
2. DropBox - Free (Andriod & IOS)
If you are afraid of losing all those precious holiday snaps DOWNLOAD DROPBOX RIGHT NOW! Create an account and upload your photos, it's also a great way to save memory on your phone if you don't have a SDCard with a massive amount of memory on it.
1. FoodSpotting - Free (Andriod & IOS)
I like FoodSpotting, it's like FourSquare, but predominantly food orientated which I fully support. It just doesn't recommend great places, but the best dishes around too. Also like FourSqaure you can adapt the settings suit your budget, so a big yes for backpackers!
There you have it folks. I hope this was useful and most importantly, happy travels!
