Several other Wikitude competitors
besides NearestWiki, my favorite being:

Cyclopedia – Also pulls from Wikipedia GPS data. Different interface, better organized.

Plus others:
Bionic Eye
WorldSurfer
Loadstone AR Compass

Some games:

Fairy Trails – game where you chase down, yes, fairies.

Firefighter 360 – action firefighter game.

ArcadeReality – shooter game.

Junaio – Metaio's mobile AR browser with some social gaming features and scalable/ rotatable 3D objects.

Peak AR – overlays to identify mountain peaks of all mountain ranges in the world.

IKEA App – (Spanish only for now) That lets you overlay their furniture in your room to see how it will look in your home before you buy.

Cheap Gas – Shows all gas stations in you vicinity will overlays of their logo, and the price they are currently sell gas at.

There are several different “Find My Car” apps. Me too apps, all almost identical in features. You click to place a GPS marker before you leave your car, then they do a floating overlay in the direction of you car so you can always find your way back to it again when you leave.

Several Different Train and Subway Finder Apps:
Nearest Tube for London
NY Subway
Also one for Paris

There is an app, I forget the name, but if you point it up at the night sky, it overlays and identifies all the constellations.

Those are the others I'm aware of, off the top of my head. I'm sure I've missed a few as well.

cheers,
Chris
