iSober is a private eye-movement impairment screen for iPhone. It uses the iPhone TrueDepth camera to run an HGN-inspired eye-movement check.
iSober is not a breathalyzer. It does not estimate blood alcohol concentration. It is not a medical device, legal test, or safe-to-drive decision.
iSober requires:
The iOS simulator and unsupported devices may show a Face ID Required screen. This is expected.
Test a Friend is the recommended mode because another person can hold the phone steady and keep the subject framed.
iSober shows an impairment signal based on detected eye-movement clues.
Results are for informational screening only. A lower signal does not mean you are sober or safe to drive. If there is any chance you are impaired, do not drive.
iSober runs eye tracking on your device. Raw camera video is not stored or uploaded. Test history is stored locally on your device unless you choose to share or copy a result.
Read the iSober Privacy Policy.
Open iPhone Settings, find iSober, and allow Camera access.
iSober needs a TrueDepth front camera. Some iPhones, iPads, and simulators do not support the required face-tracking feature.
Try these steps:
iSober is not a definitive impairment test. Eye movement can be affected by fatigue, medications, neurological conditions, lighting, camera position, and user movement. Do not rely on iSober to decide whether to drive.
