NoGlasshole

A privacy-first iOS app that detects nearby smart glasses via Bluetooth and blurs faces in photos and videos. All processing happens entirely on-device — no cloud, no accounts, no data leaves your phone.

Features

Smart Glasses Detection

• Real-time Bluetooth Low Energy (BLE) scanning to identify nearby smart glasses
• Recognizes Meta Ray-Ban, Snap Spectacles, and other smart eyewear using manufacturer advertisement data
• Live radar UI with signal strength and detection log

Face Blur for Photos & Videos

• Automatic face detection powered by Apple's Vision framework
• Three blur modes: Gaussian blur, pixelation, and solid black mask
• Selective blur — tap to un-blur specific faces while keeping others obscured
• Adjustable blur intensity and mask coverage
• Video processing with temporal face stabilization to prevent flickering across frames

Smart Glasses Media Detection

• Scans your photo library for media imported from smart glasses
• Identifies Ray-Ban Meta photos via EXIF metadata and filename patterns
• Organized view separating smart glasses media from the rest of your library

Tech Stack

• SwiftUI — UI framework
• Vision — Face detection with GPU/CPU fallback
• Core Image — Image and video filtering
• AVFoundation — Video composition and export
• CoreBluetooth — BLE scanning for smart glasses detection
• PhotoKit — Photo library access and EXIF parsing

Requirements

• iOS 17.0+
• Xcode 15+

Getting Started

1. Clone the repository
2. Open nohole.xcodeproj in Xcode
3. Build and run on a physical device (BLE scanning requires a real device)

Privacy
