Windows Phone's Word Flow keyboard is coming to ‘other platforms’ starting with iOS

Context & Ripple Effects
In January 2016 Microsoft broke Word Flow out of Windows Phone and committed to bringing its keyboard to rival platforms, starting with iOS — an early move in the company's shift toward shipping first-party software where the users actually are. Within weeks it was testing a distinctive fanned layout for one-handed typing, and by April the keyboard reached iPhones as a public release with one-handed mode and custom backgrounds.
The arc matters because it ended quickly: by mid-2017 Microsoft had shut Word Flow down on iOS and pointed users to SwiftKey, folding its keyboard ambitions into an acquired asset rather than a homegrown one.
First-order effects
- iPhone users gained a Windows Phone-native keyboard with one-handed mode as a free download, while Windows Phone lost one of its few genuinely differentiated input experiences.
- Microsoft's own mobile platform ceded a marquee feature to iOS, signaling internally that reach mattered more than exclusivity.
Second-order effects
- Word Flow's entry crowded an already competitive iOS third-party keyboard field, forcing incumbents to compete on gesture innovation like the fanned arc layout rather than just theme stores.
- Once SwiftKey was in Microsoft's portfolio, maintaining two parallel keyboard codebases became redundant — the shutdown redirected Word Flow's user base straight into Microsoft's preferred product.
Third-order effects
- The pattern — build on your own platform, port to rivals, then consolidate around acquisitions — previews how large platform vendors now treat mobile apps as audience-capture tools rather than OS differentiators.
- Keyboard software specifically drifted toward consolidation under a few large owners, since prediction quality depends on data scale that standalone indie keyboards struggle to match.
The trend: Platform vendors are decoupling their flagship apps from their own operating systems to compete for users on rival platforms, even at the cost of eroding their own exclusives.
