Gboard is Google’s official keyboard app. It’s a simple keyboard that doesn’t have too many frills. It does have gesture typing (swiping), light theming, voice typing, emoji search, GIF support, and more. Its most unique feature is the built-in Google search that lets you search the web without leaving the keyboard or app that you’re in.
It can also sync between devices so your saved words go with you. It’s effective, simple, and 100% free. You’ll want to try this one out if your phone keyboard is giving you fits. It’s one of the best free Android apps for sure. SwiftKey is also great and it’s basically completely free these days too!
