Is Your Neck Okay?
Your head weighs about 5 kg. When using a PC or smartphone, do you know how much strain you're putting on your neck? If your neck is straight, it's about 5 kg. Tilt it 30°, and it's 18 kg. At 45°, it becomes 23 kg. At 60°, it reaches a massive 27 kg!*1 Your neck is under this strain continuously.

What If There Were Software That Could Reduce Neck and Back Strain and Help You Maintain Beautiful Posture?
When working at your PC, is your neck and head jutting forward, and your upper back rounding? If you’re experiencing neck or back pain, your posture may be to blame.
