TextExpander 3 + Custom Keyboard for iOS
TextExpander 3 is another in a long line of apps taking advantage of awesome new features in iOS 8. It comes with a custom QWERTY keyboard that lets you expand text snippets within any app—not just the ones using the old SDK—and without having to rely on iOS' built-in keyboard shortcuts. This is a huge deal for those of us who are practically lost without our snippets.
TextExpander 3 is a universal app and just $5 on the App Store.
