The keyboard evolved from an in-app feature to an independent app that can be used within all other apps installed on user's phone.
Its experience also evolved, it started as an app along with a tactile screen guard to complement. Later, we removed that and replaced with vibration feedback on particular of UI elements. Later, we replaced that too and included mix of sound and color contrast along with vibration in center portal only.
