Word Flow, a Microsoft Garage project, is an iOS app with a blazing fast keyboard that comes with search (GIFs, restaurants, and more), free customization options and includes Arc mode for comfortable one-handed typing.

Blazing Fast

  • Whether you’re tapping or swiping, Word Flow predicts what you’re trying to type and corrects mistakes. It even predicts things from the web, like GIFs, restaurants, and more.
  • Word Flow intelligently suggests the next word in your sentence, and gets better at it over time, as it learns your typing patterns.
  • With access to your Contacts, Word Flow predicts the names of your contacts so you can go even faster.

Personalized – just how you like it

  • You can customize the keyboard background using one of the images included in the app, or use your own favorite image.
  • All the images included with the app are free.

Best for one-handed typing

  • Switch to Arc mode and easily reach keys on larger screens for a more comfortable one-handed typing experience.

Search built into the keyboard

  • Find and share GIFs, images, and emojis to better express yourself.
  • Find Contacts – when you need to share that person’s phone number.
  • Look up restaurants, news, videos, facts, weather forecasts, and much more.

When you find something you want to send, just tap it, and that result will automatically stay in your history to make it even easier to find it again. If a result becomes outdated or irrelevant, you can always remove or refresh it. Word Flow on iOS is optimized for iPhone, and supports English language only. Not all features are available on iPad.

Nowadays when people text, they don’t just communicate with words. They like to express themselves with lots of emoji, animated GIFs, and memes. In this release of Word Flow, we’ve made it easier for you to find and share GIFs, emoji, contacts and more – all without having to leave the keyboard! Simply swipe above the keyboard (where the word suggestions are) and search for what you want.

We’ve also made it easier to share rich content such as contacts and restaurants. For example, with location enabled, search “Restaurants near me”. For any restaurant card, you can share a full snapshot (with ratings and hours), or just a portion, such as the location. You can also take actions like calling the restaurant.

As you type, the keyboard will not only suggest words and emoji, but also popular GIFs, images and even search queries. If you’ve enabled contacts, the keyboard will not only suggest the correct spelling of that difficult name, but also pull up the contact card for you to share. And if you’ve enabled location, it will help you both type and share popular local businesses.

With these new suggestions, we hope to make messaging more fun and productive! We’d love to hear what you think.
