About this app

Worried about a hidden camera or a listening bug in your hotel room, Airbnb, rental, or changing room? Zavira gives you 5 scanning tools to sweep a room in minutes. Every scan runs on your own device, offline, with no account.

── 5 DETECTION TOOLS ──

Wi-Fi Scanner
Lists nearby Wi-Fi names and the devices on your network, flagging names typically used by IP cameras and DVRs — IPCAM, V380, Yoosee, Hikvision and similar.

Bluetooth Scanner
Reads the Bluetooth LE advertisements around you and sorts them into plain categories: possible camera or recorder, tracker tag, headphones, watch, smart home device, or an unnamed signal. Distance is shown as Very close, Nearby, or Farther away instead of raw signal numbers.

Bluetooth Tracker Tags
The Bluetooth scan flags locator tags — Apple Find My / AirTag-style signals, Tile-type tags, and devices advertising a locator profile — as "Tracker or locator signal", so you know to search bags, coats, luggage linings, shelves, and decorations.
Being straight about the limits: this is a scan you run, not a background watchdog. It does not monitor while the app is closed, it does not track a tag over time to tell you whether it is travelling with you, and it cannot make a tag play a sound. Android's built-in unknown tracker alerts do those things — use both.

Lens Finder
A camera preview with the flashlight, to help you catch the bright circular reflection of a lens in smoke detectors, clocks, sockets, vents, and mirrors.

Magnetic Detector
Reads your phone's magnetometer and warns on a spike against a calibrated baseline. Remove magnetic cases, wallets, and ring holders first, then recalibrate.

Room Checklist
A guided 10-point sweep of the places cameras are usually hidden.

── FREE VS PRO ──

Free: all 5 tools, every scan, and every result, with the same warnings. This app never hides a finding behind a payment. If something suspicious is in your room, you see it.

Pro adds convenience, not access:
- Scan history kept between sessions
- An exportable PDF or text report — location, time, what was checked, what was found — for a hotel, a landlord, or the police
- Deep scan: repeated passes with a longer listening window

── WHY THIS APP ──

- Runs entirely on your device; scans are never uploaded
- Works with no internet connection
- No account, no sign-in, no registration
- Plain-language results instead of raw signal dumps
- One-time purchase available — a subscription is not required

── HOW TO USE ──

1. Tap Scan Room for a guided sweep
2. Run the Wi-Fi and Bluetooth scans first, then inspect by hand with the Checklist and Lens Finder
3. Name the location so it appears on your report

── PERMISSIONS ──

Location — required by Android to scan Wi-Fi and Bluetooth. Your coordinates are never read or stored.
Camera — used only for the Lens Finder preview. Nothing is recorded or saved.

── IMPORTANT ──

This app supports a manual inspection using the sensors in an ordinary phone. It is not a certified counter-surveillance device and cannot prove a room is clear: a camera that is switched off, wired-only, or recording to a local card without transmitting may not appear in any scan. If you genuinely believe you are being recorded, contact local authorities.

What’s new

Polish pass on the translations: the history tile no longer cuts its own label off, and the Wi-Fi scan summary counts devices with the right grammar instead of always using the plural.
