Predictable is a text-based communication aid app for iPad, Android and Windows. You can access the Pad version via touch, switch and head tracking, and from iOS 13 onwards, mouse or external pointing device. Predictable is designed for people who are literate but have lost the ability to speak possibly due to cerebral palsy, motor neurone disease, laryngectomy, stroke, apraxia or brain injury. The app offers a choice of 5 keyboards and has word prediction and phrase selection to speed up communication.
