I was surprised to find out how few of my friends use these awesome mobile apps and decided to write this post. I'll be happy if some of you will find it useful. All screenshots are made by me.
Wikipedia
Of course everyone knows about Wikipedia, the best online encyclopedia ever... but I've mentioned that most of my friends open the article in web browser. Just start using this one now - it will make your experience with Wiki much smoother: you can create a reading list, change the font size and easily navigate through the text.
Fabulous
I used to be a great procrastinator at the uni, and this app became one of my best helpers. It simply helps you to create routines and track your everyday habits. Oh yes, the app also looks awesome. Just try it to finally put yourself together if you are a couch potato too.
Google trips
There are a lot of great apps for keen travelers, but very few of them (if I'm not mistaken) use Google Trips. Try it for your next trip! It will help you find information about the place and even suggest some ready-made plans. It will also offer you discounted tours and services.
QuizzLand
I'm not a fan of trivia games, but this one is a wonderful time killer. It is beautiful, it is fast, it is highly educational. You will answer questions on different topics and read detailed explanation for each of them (even if you don't answer right). There are also daily and weekly local competitions. I believe you should also try this one and try to outsmart me ;)
RetroArch
This one allows you to download different console emulators directly through the app and play old games from your childhood. It got me nostalgic, maybe some of you want to feel this way too.
