It's hard to believe that just half a decade ago, apps weren't a "thing".

If you wanted to game on the go, or be productive while mobile, your choices were few, you were usually limited to the in-built software for your phone.

With apps, though, pretty much anything's possible. You can use your phone to get a taxi, identify a song, write documents, find recipes, DJ, play all manner of games, and much more.

So with this in mind, we're celebrating this landmark along with our friends at PocketGamer.biz, 148Apps, AppSpy and beyond, over on the Best App Ever Facebook Page.

Our editors and regular contributors will be documenting their five favourite apps and games of the last five years, along with their hopes for the App Store in the future.

We'd love for you to be a part of it too. Share your favourite five games, and your wishes for the store moving forward, over on the Best App Ever Facebook Wall.
