Detection
Ask what signal is measured: scheduled inactivity, camera-visible eyes, head position, wearable motion, or vehicle behaviour. Each has blind spots.
Privacy and runtime
Check whether frames or biometric data leave the device, whether an account is required, and whether monitoring continues when another app is in front.
Alerts and controls
Compare test alarms, sound randomisation, haptics, custom recordings, sensitivity controls, and a clear way to acknowledge or stop an alert.
Safety honesty
Prefer products that publish limitations and do not claim to make fatigued driving safe. Built-in vehicle systems should be used according to the manufacturer’s instructions.
