IOS 18

Eye Tracking, added to iPhone and iPad with iOS 18 The free way to find out whether eye control suits you before spending on specialist hardware. It uses the front camera, with no extra accessories, and calibrates in seconds; you look at an item to highlight it and hold your gaze to select it with Dwell Control. Apple keeps the setup and control data on the device. Be realistic about it: a phone screen is small, and the device needs to stay put in a mount, because moving your face or the phone can mean calibrating again. For full-time use a dedicated tracker is steadier, but as a taster, or for someone who only struggles on tired evenings, it costs nothing.
