Swift Key, Android's most popular keyboard app, could soon be coming to iOS in the form of a note-taking app.

It's not clear when the app would be available or how much it might cost. Swift key hasn't yet commented on a potential iOS release.

Apple still doesn't allow third-party developers to change the native keyboard on iOS so, unlike Android versions, any iOS iterations of Swift Key will be limited to individual apps.

But, as Cult of Mac points out, if Swift Key makes its keyboard available to other developers, it could potentially pop up in more apps in the future.
