A few years ago Swiftkey was the hottest thing on the app store. Soaring well ahead of Google keyboard as the go-to option for most Android users. They were the first to truly make word prediction useful on our smartphones. Predicting what we want to say before we say it, and saving users time. Not to mention spell check was on point, and it has loads of themes for customization.
The "fluency engine" is what they use to predict what we want to say, and the keyboard learns from the user as time goes on. Making it more accurate, even with slang and words you say, instead of just average users. It was a paid app for a long time, but in 2014 became forever free. Now we just pay for new themes and color choices, if needed.
Additionally, Swiftkey is the engine behind Samsung's keyboard, most just don't know it. So if you've recently switched phones and want that same amazing experience back, Swiftkey is for you. Those looking to try something new or don't like Gboard, this is the next best thing.
