Prolonged forward head posture from phone use can lead to a wide range of issues
"Phone neck" (or "text neck") is a condition caused by habitually tilting your head downward while using your smartphone, placing excessive and sustained strain on the cervical spine.
This posture can lead to more than just neck and shoulder stiffness. Over time, it may contribute to headaches, dizziness, and general discomfort. The longer poor posture continues, the more the strain on your body can accumulate.

Your head weighs about 12 lbs, and the load on your neck increases dramatically as you tilt forward
According to a 2014 study by Hansraj, the weight of the head at a proper upright posture (0°) is about 12 lbs (5 kg). At the typical smartphone usage angle (60°), that load increases to approximately 60 lbs (27 kg) on your cervical spine. That's the equivalent of carrying a small child on your neck all day long.

Keep the posture your care gives you, every day.
Chiropractors and stretching are professional care that resets your posture. But once you're back to daily life, it slowly slips again. LookUp fills the gap in between — just use your phone and it notices your posture effortlessly, helping the results of your visits and self-care last every day.
Posture apps take different approaches. What sets LookUp apart: it senses your real-time posture while you just use your phone as usual.
