Do you have any apps on your device which you think no-one else reading the site would have? If so, what are they?
Fnorder, Vanitas, Bitboxland.
MarineTraffic is the only reasonably esoteric app on my device.
I've a couple of shortcuts to webapps, and I know one of them is unique since I wrote it myself, although it is nothing more than my own incarnation of ReadItLater / Reading List. The other is the web client for the server which sends the commands to the lighting system (remotestick).
Security app for real time tracking of one of my cars.
Unless there's another Canadian around, I wouldn't expect anyone to care about the Canadian Tire Store App, the Tim Horton's App, or the Canada Post App. Probably no one has the CBC (Canadian Broadcasting Company) Hockey Night in Canada App or a number of other Canadian sports TV Apps. How about the more general Hockey Rules App.
Anyone else have Game for Cats or Cat Piano? There must be cat lovers out there.
Wine anyone? Natalie MacLean's Wine Picks & Pairings.
Something more general? How about Symbolic Calculator which lets you enter formulae as you would write them.
Anyone got xkcd? It's a web comic that's quite good.
Anyone manage to snag a copy of Tris, a Tetris clone, before it was pulled a few years back?
Possibly the Next shopping app for the UK. I get a lot of my clothes there. Priority Pass lounge directory for airports. Oh and Steven Tyler (Aerosmith) AppSoLewdly which is quite funny.
Flightradar. Open app. Aim camera at plane in sky and you get all the info on the plane and flight.
Ocarina - blow in to the mic whilst playing the instrument on the screen with fingers.
Nike+ GPS - tracks your run on map.
