Serin turns your iPhone into a personal privacy scanner. It looks for the devices that watch you — smart glasses, hidden cameras, and Bluetooth trackers — and tells you what is nearby. CANARY MODE A single glanceable status orb. Green means your surroundings are clear of known recording devices. Amber and red mean something worth a look. WHAT SERIN FINDS • Camera glasses and AI wearables — smart glasses, Spectacles, AI pins, and similar recording hardware • Bluetooth trackers — anonymous tags that stay near you across time are flagged after sustained proximity • Networked cameras — IP cameras, streaming devices, and smart-home hardware on the WiFi you are connected to • Hidden lenses — infrared reflection scanning to spot camera optics in a room ROOM SWEEP & TRAVEL SWEEP Guided walkthroughs for hotel rooms and rentals. Serin steps you through each zone, records what it finds, and produces a shareable report. DIGITAL MIRROR See what your own devices broadcast to everyone around you. PRIVACY BY DESIGN No account. No sign-up. Detections stay on your device and sync only through your private iCloud. Serin never uploads location or scan history. SERIN PRO — ONE PURCHASE, NO SUBSCRIPTION • Infrared camera finder • Full travel sweep with PDF export • Deep network scanning • Live Activities on the Lock Screen • Personal insights and trends • Unlimited detection history • No ads IMPORTANT Serin detects wireless signals and visible optical reflections. It cannot find devices that are powered off, hardwired without wireless, or shielded. Signal strength indicates rough proximity, not exact distance. Serin is an awareness tool, not a tool for confrontation, investigation, or emergency response.

Trace is your personal phone security guardian. Modern phones face constant threats — sketchy Wi-Fi networks, unknown Bluetooth trackers, and the looming question of who or what is nearby. Trace gives you instant visibility and clear actions, so you can move through the world feeling confident about your privacy. WHAT TRACE DOES - Bluetooth Tracker Detection Detect AirTags, Tile, Chipolo, and Samsung SmartTags around you — identified by brand. Trace's persistence engine watches devices over time and flags ones that keep reappearing as you move, even when they rotate identifiers to evade tracking. Alerts include how many times a device has been seen and whether it's following you across locations. - Wi-Fi Network Analysis + Speed Test Identify spoofed networks, evil-twin attacks, and unencrypted public Wi-Fi before you connect. Free built-in speed test measures download, upload, latency, jitter, and packet loss. Get clear "Safe / Caution / Dangerous" verdicts based on real threat intelligence. - Live Threat Feed Stay informed with curated alerts from CISA, Apple Security, Android Security, FTC scam warnings, data breach alerts from Have I Been Pwned, privacy news from the Electronic Frontier Foundation, and stalkerware research from the Coalition Against Stalkerware. Updated automatically. - Personalized Recommendations Get clear, step-by-step instructions to harden your phone's security settings. From two-factor authentication to lockdown mode, Trace tells you exactly what to do. - Background Tracker Scanning Trace keeps watching for trackers even when the app is closed. Get a notification if something persistent is following you — with brand and pattern details, not just a generic warning. - Trend Tracking Watch your security score evolve over time. See how your habits, environments, and choices affect your privacy posture. WHY TRACE IS DIFFERENT Most security apps either oversell what they do or focus on enterprise customers. Trace focuses on what's actually possible on iOS and gives you clear visibility into the rest. Built by an indie developer who believes privacy is a basic right.
