Catch tech neck the moment it starts - even while you use other apps. Neck Saver floats a small posture monitor over any app with Picture in Picture. It turns red when you hold your phone at a neck-straining angle and green when you hold it up at a healthy angle. No reminders to dismiss, no timers: just a color you notice at a glance while you scroll, read, or chat. HOW IT WORKS • Your iPhone's motion sensors detect how far you tilt your phone, in real time. • The posture monitor stays on screen in Picture in Picture while you use other apps. • Look down too far and the color shifts to red. Lift your phone and it goes back to green. FEATURES • Always-on posture monitor over other apps (Picture in Picture) • Real-time tilt detection with the gyroscope • Choose the monitor width: Thin, Regular, or Wide • Pinch or double-tap to make the monitor larger or smaller • Color themes - 2 free themes, plus extra themes available as in-app purchases GREAT FOR • Anyone worried about tech neck, text neck, or forward head posture • Long sessions on social media, videos, games, or reading • Building a habit of holding your phone at eye level Terms : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy : https://co-okchem.com/pp240420/405/
