iOS: We all know text expansion is great, but sometimes it's hard to remember the abbreviations you make. TypeSnippets solves this by making it a more visual experience.
Once you create your snippets, you can just pull up the keyboard and click on options such as "phone number", "website" or "Twitter". It's all about keeping a quick log of the snippets you use most of mobile and for those purposes it works really well. Of course, you can always set up your own shortcuts, but TypeSnippets makes them easier to pull up. TypeSnippets is similar to the previously mentioned KuaiBoard, but sports a design that's a little easier to navigate through quickly.
