Acronymph, developed by Calvin Robertson, is an iPhone app to discover the meaning of acronyms.
With a variety of built-in categories that range from Internet slang and sports to music, economy, and goverment acronyms, Acronymph simply displays matches it finds in its built-in database. You can’t configure sources you want to see/hide because the app has no settings, but a recent update added a URL scheme that lets you send an acronym from apps like Launch Center Pro or Drafts directly to Acronymph without having to tap the app’s search box and type.
When results are found, you can tap on them to copy them, open a Google search, or share them to other apps. I’m nitpicking, but I don’t like how “@AcronymphApp” is appended to an acronym’s meaning when you’re sharing a result to Mail or Twitter.
Acronymph is simple and effective. I’ve looked up several acronyms in the past weeks and the app always found meanings in less than two seconds; it’s the kind of utility that you likely won’t need on a daily basis, but that will come in handy if you don’t need a full-featured dictionary app like Terminology. And, btw, Acronymph is $0.99 on the App Store.
