My first Sticker Pack for iMessages on iOS 10 is now available! Grammar Snob #grammaredhttps://t.co/EtwF5VcWWX pic.twitter.com/wCATHoH6FN — John Haney (@johnhaney) September 15, 2016

Besides the obvious one (to / too / two, your / you're, we're / were and so on), the pack also offers some corrections for commonly misspelled words like espresso, figuratively and more. There are also a bunch of generic cross-out and insertion stickers, so you can really fix the horrible messages your friends send you. The app will set you back a buck on the iTunes Store, and it's probably the smartest use of stickers we've seen thus far.

Of course, just be aware that being a grammar snob is often the quickest way to make your friends ignore you completely. Still might be worth it, though.
