Detection method
Check whether the app measures visible eye closure, PERCLOS, head pose, device motion, or a combination. Ask what happens when the face disappears.
Background operation
Verify whether monitoring continues behind navigation, whether picture-in-picture is required, and whether the operating system can suspend camera access.
Privacy
Check whether frames are stored, uploaded, or used to create detection snapshots. Similar-sounding on-device claims can hide different retention behaviour.
Alerts
Compare test controls, sound variety, haptics, acknowledgement, escalation, output routing, and whether alarms stop when the session stops.
Safety language
Reject claims that an app prevents crashes or guarantees safe driving. A responsible app tells a drowsy user to stop and rest.

EyeJolt focuses on local processing, randomized alarms, cross-platform stationary use, and explicit limitations. Driving use remains a supplementary warning only.
