What is PrivacyScreen?

PrivacyScreen is a Swift package for iOS 17+ apps that acts as a software privacy screen protector, using ARKit face tracking and CoreMotion sensors to detect shoulder surfing. It spots second faces peering over your shoulder, gaze shifts, or suspicious device tilts, then progressively blurs marked sensitive UI elements—like balances or card numbers—while keeping everything interactive. At peak threat, a full-screen shield kicks in, all without blocking touches.

Why is it gaining traction?

Unlike physical privacy screen protectors, this privacy software fuses sensors into a privacy-by-design layer for SwiftUI, with tunable sensitivity sliders and power throttling that cuts battery drain by duty-cycling ARKit. Devs love the dead-simple integration: tag views with a modifier, add an overlay, and get a polished demo app showing real-world finance UI. Simulator support via threat simulation means quick testing without hardware.

Who should use this?

iOS developers building banking or fintech apps with SwiftUI, where users handle balances, cards, or transactions on the go. Security-focused teams in health or e-commerce wanting software privacy filters to shield against casual onlookers, without rewriting UIs. Avoid if you're on older iPhones without TrueDepth cameras.

Verdict

Grab it for prototypes or niche privacy needs—excellent docs, 29 unit tests, and a demo make evaluation easy, despite 10 stars and 1.0% credibility signaling early maturity. Solid for github software download in privacy screen experiments, but watch for production hardening.
