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/

Verdict
The clearest difference is in-app purchases: WILL at none against Neck Saver's 3. WILL also leads on iOS requirement (8.0 vs 17.0). Neck Saver's advantage is update cadence (weekly vs every 42 months). On price, ads and device support there is nothing between them.
