Google's Gboard for iOS offers everything you'd expect from a keyboard. But it goes further by providing built-in search to hunt for information that you can easily share with messaging partners.
Built-in search: As you might expect from a Google app, Gboard efficiently integrates search and messaging, either with Apple's messaging app or third-party SMS and MMS apps.
Accurate swiping: With Gboard's Glide Typing, slide your finger over keys to create your message. We found Gboard did a good job of accurately detecting words as we swiped. Another handy gesture: The space bar acts as a tiny trackpad -- swipe over it quickly to navigate a text message.
GIFs and emoji: Tap the Emoji icon to the left of the space bar to access Gboard's collection of emoticons, emojis, and GIFs. A search field above the collection lets you hunt for an appropriate GIF or emoji instead of swiping through the library.
Privacy: Google says that except for searches, nothing that you type (such as chats or passwords) is sent to the company. Google does collect usage statistics.
Multiple languages: Gboard supports multiple languages and will automatically detect and autocorrect messages for whichever supported languages you are using.
Not complete parity across Android and iOS: The iOS version of Gboard lacks a few features found on the Android side, including voice dictation.
Google's Gboard provides the basics you'd want in a keyboard but goes a step further by including built-in search that lets you share results in a message without leaving the chat app.
