The app currently supports 32 common shapes for learning, estimation, and everyday work. With Geometry Calculator you can: • calculate area, perimeter, volume, and other common results • switch length, area, and volume units instantly • review formulas, variable meanings, and result details • use inverse solve for selected basic shapes • save presets, favorites, projects, and history • export PDF files or share results • switch among 15 languages and light or dark appearance The free version includes 2 planar and 2 solid shapes. Upgrade to Pro with a one-time purchase to unlock every shape and the full calculation workflow. Unless you choose to share, your history stays on your device.

Argus is a counter-surveillance field instrument for iPhone. It turns your phone into a six-tool sweep kit for travelers, hosts, parents and privacy-minded users — built to check any room for hidden cameras, listening devices, BLE trackers and rogue WiFi nodes in roughly three minutes. Most "spy detector" apps do one trick (a magnetometer dial in a fake radar UI) and call it a day. Argus rejects that model. It chains real iPhone sensors into a structured sweep protocol that mirrors how counter-surveillance teams actually inspect a room. — WHAT MAKES ARGUS DIFFERENT — ◉ A real protocol, not a single trick Six independent detection methods, each surfacing a different class of threat. Every reading folds into a structured dossier. ◉ Six instruments, one workflow Optical lens reflection, infrared light source, WiFi network audit, Bluetooth Low Energy scan, magnetic field meter, maximum-brightness flashlight beacon. All driven by real iPhone telemetry. ◉ Guided room presets Six location presets — Hotel, Airbnb / Vrbo, Office, Bathroom, Changing Room, General — each walks you step by step through where to point, what to listen for and what to flag. ◉ Threat Map (unique to Argus) Every sweep is geotagged and pinned on a MapKit view, color-coded by threat level. Browse every hotel, rental and venue you've checked. Useful for frequent travelers and hosts auditing their own units. ◉ Sweep Dossier reports Each sweep produces a shareable PDF report (safety score, flagged devices, timestamps, findings). Records live on-device. ◉ Field Manual built in Real counter-surveillance tradecraft — how spy cameras hide, how to spot them, your legal rights, what to do if you find one. Researched content, not filler. ◉ Privacy by design No account. No cloud sync. No telemetry. The app works fully offline. Useful in hotel WiFi situations where you don't want to broadcast what you're doing. — INSTRUMENT REFERENCE — ◉ Optical Lens Scan — flags reflective glints from camera lenses hidden in mirrors, smoke detectors, vents and décor. ◉ Infrared Detector — surfaces invisible IR light sources from night-vision spy cameras via the front sensor. ◉ WiFi Network Audit — enumerates every device on the local network and flags unknown vendors and rogue cameras. ◉ Bluetooth RF Sweep — discovers BLE transmitters in the 2.4 GHz band, including Bluetooth item trackers and BLE bugs. ◉ EMF Magnetic Meter — baseline + peak detection of magnetic anomalies from electronics hidden behind walls and furniture. ◉ Flashlight Beacon — maximum-brightness mode for manual lens-glint inspection. — QUICK SCAN PRESETS — Hotel Room · Airbnb / Vrbo · Office · Bathroom · Changing Room · General. Each preset chains the relevant instruments into one dossier. — WHO ARGUS IS FOR — • Travelers checking hotel rooms before unpacking • Airbnb / Vrbo guests auditing short-term rentals • Hosts inspecting their own properties • Parents checking rooms, dorms or daycares • Anyone in shared housing, gyms or rentals • Privacy-conscious professionals on the road — IMPORTANT — No consumer app can guarantee 100% detection of every hidden camera or covert device. Argus is a supplementary tool that helps a careful user inspect a room more thoroughly than they could unaided. Use Argus to sharpen awareness, structure the sweep, and create a record — not to replace common sense. — PRO ACCESS — Unlimited sweeps, all six room presets, PDF dossier export, ad-free. Weekly, yearly or lifetime. — LEGAL — Terms of Use: https://pnkl26.web.app/terms-of-service Privacy Policy: https://pnkl26.web.app/privacy-policy — SUPPORT — pnkhanhlinh0206@gmail.com
