Android's most popular keyboard app, SwiftKey, could be coming to iOS soon. An image leaked on Twitter Thursday shows SwiftKey Note, an app featuring the popular keyboard.

For now, it's not clear how much the app would cost, and SwiftKey hasn't yet commented on a potential iOS release.

Apple doesn't allow third-party developers to change the native keyboard on iOS yet, so it will be unlikely that SwiftKey would be able to do so. Cult of Mac points out if SwiftKey makes its keyboard available to other developers, it could potentially pop up in more apps in the future.

The $3.99 keyboard app is only available for Android users for now.
