Track and compare image-based changes over time using the iris as a relative scale. Records stay on your device and can be exported as reports. LidTrack helps you privately record and compare visible changes in your eyelid over time. When an eyelid develops visible swelling or redness, it can be difficult to remember whether its appearance is improving or changing. LidTrack provides a consistent way to photograph, measure, and review these changes. LidTrack uses the visible width of the iris as a relative reference. This helps reduce differences caused by camera distance and image scaling. For more consistent trend records, use similar lighting, angles, and photography conditions each time. KEY FEATURES • Capture and organize eyelid photos • Mark and measure a selected eyelid area • Compare measurements using an iris-based relative reference • Review changes and trends over time • Add notes to individual records • Generate clear PDF reports • Export reports only when you choose • No account or registration required • Photos and records remain on your device PRIVACY BY DESIGN LidTrack does not require an account and does not upload your photos or health records to a developer-operated server. Your records are stored locally on your device. You control when and where exported reports are shared, including saving them to Files or your personal iCloud storage. IMPORTANT LidTrack is a personal tracking and documentation aid. It does not diagnose medical conditions, evaluate treatment effectiveness, or replace professional medical advice. Always consult a qualified healthcare professional regarding symptoms, diagnosis, or treatment.
