In Android contexts, should the 'a' in 'app' be uppercase always or lowercase?

Lowercase unless it appears as the first word of a sentence or at the end of the name of a proper application. Why would it be capitalized? –  virmaior Feb 24 '14 at 5:08

Lowercase, except at the beginning of a sentence. App is short for application. And, given that you wouldn't capitalize application, no need to capitalize app.

In a formal paper, you should consider writing out application. At least for the first usage like this: application (app).

Here is a search of the word app on Engadget. Note the consistent lowercase usage. (Click to enlarge:)

While I'd also consider writing out 'application' for a formal paper, there's something to be said for 'app' being proper use to describe a mobile application - similar to radar, scuba, laser, modem, etc. All of which I'm sure are not written out in every formal paper anymore. –  Doc Feb 24 '14 at 6:57
@Doc I think that it depends upon the level of formality and subject matter. If it were a paper on the application of scuba, I would say: Self-contained Underwater Breathing Apparatus (SCUBA) and go from there. If it were about underwater caves, I would say: many of the newly discovered lifeforms can only be found by the use of scuba gear. –  David M Feb 24 '14 at 7:00
