Paralleye monitors your phone angle in real time and alerts you before poor posture causes neck and upper back strain.
Paralleye uses your device's motion sensors (accelerometer & gyroscope) to measure phone tilt angle. No camera or microphone is used. Anonymised angle data is shared with the Health Promotion Board for research.

Neck care tips
🎯
The golden angle
Hold your phone closer to eye level. Each 15° of forward head tilt adds approximately 10–12 kg of extra load on your cervical spine. At 60°, that's equivalent to carrying a 27 kg weight on your neck.
⏱️
20-20-20 rule
Every 20 minutes, look at something 20 feet away for 20 seconds. This relieves eye strain and naturally resets your head position.
🧘
Chin tuck exercise
Gently pull your chin straight back (not down). Hold for 5 seconds. Repeat 10 times. This strengthens the deep cervical flexors and counteracts forward head posture.
💪
Neck stretch sequence
Slowly tilt your head to the right, holding your left shoulder down. Hold 20 seconds each side. Follow with gentle neck rotations — 5 circles each direction.
🪑
Posture while sitting
Sit with your back against the chair, feet flat on the floor. Hold your phone at chest-to-eye level. Avoid crossing legs as this tilts the pelvis and affects spinal alignment.
⚠️
Warning signs to watch
Persistent neck pain, headaches originating at the base of the skull, tingling in fingers, or shoulder blade aching after screen use — consult a healthcare professional if these occur regularly.
