Worried someone is watching? Check into any hotel, Airbnb, or rental and sweep the room for hidden cameras and spy devices. NSpy is a hidden camera detector that turns your iPhone into a portable counter-surveillance kit — no extra gear, no tech skills required. Hidden cameras are smaller and cheaper than ever. A pinhole camera can hide inside a smoke detector, an alarm clock, a power outlet, a USB charger, or an air vent. NSpy gives you three detection methods to help you look for them and check your space. How NSpy works • Wi-Fi network scanner — lists the devices on the same Wi-Fi network and flags camera-like and microphone-like hardware as suspicious, so you know where to look first. • Infrared (IR) view — dim the lights and use the color filters to help you spot the glow of night-vision IR LEDs, which is invisible to the naked eye. • Magnetic field detector — uses your phone's magnetometer to show magnetic changes near clocks, vents, outlets, and smoke detectors, helping you narrow down where to look. What you get • Three scan methods in one app, each started with one tap • Per-device detail view to inspect anything suspicious on the network • Flags network-connected microphones and audio devices on the same Wi-Fi • Step-by-step "how it works" guide so you know exactly what to look for • Clean, private interface — your scans stay on your device • Multi-language support and responsive in-app support Who it's for • Travelers checking into hotels, motels, and short-term rentals • Airbnb and vacation-rental guests who want peace of mind on arrival • Renters and tenants inspecting a new apartment or room • Parents checking a child's bedroom or a babysitter's space • Business travelers securing a room before a private meeting • Domestic-violence survivors and anyone worried about being watched or stalked • Anyone uneasy about a bathroom, changing room, locker room, dressing room, or gym Why NSpy When you walk into an unfamiliar space, you shouldn't have to wonder who's recording you. NSpy combines a Wi-Fi scanner, an infrared camera viewer, and an EMF/magnetic detector into one focused privacy tool built for one job: helping you check for hidden cameras, spy gear, and listening devices. It's a hidden camera finder and bug detector you can carry everywhere. A few quick notes: NSpy is a privacy and counter-surveillance scanning tool, not a guarantee against every covert device. No detector app can promise it will find 100% of hidden cameras, so use NSpy together with a careful visual inspection of mirrors, vents, and electronics. NSpy is not an antivirus, a Wi-Fi speed test, or a Bluetooth tracker finder. Download NSpy and take privacy back into your own hands. Scan your next hotel, rental, or meeting room with confidence. Pro unlocks unlimited scans, infrared color filters, magnetic field detection, and complete device reports. NSpy offers optional paid subscriptions for access to certain features. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled at any time in your App Store account settings.

About

Smart Home 3D

Read full description

See which lights are on, at a glance. Smart Home 3D puts your smart home on a 3D floor plan. Rooms, floors, furniture and lights appear where they belong. Glass walls reveal the interior, so you can see lighting states and control supported lights in their place. YOUR HOME IN 3D Scan rooms with RoomPlan on a compatible iPhone or iPad with LiDAR. Add floors and stairs, and edit walls, doors and windows. Switch between glass, architectural and top-down views. Metric rulers, guides and snapping help refine your plan. Set precise wall dimensions and angles, and add balcony doors and rolling garage doors. LIGHTS IN THEIR PLACE Place chandeliers, individual spots or groups, switches and LED strips. Mark lights through the camera and set a strip's start and end points. Link them to available devices and circuits. Tap a light or room to control supported lighting. Brightness, colour and colour temperature depend on your device and provider. FURNITURE AND YOUR MODELS Furniture recognised during a room scan appears in your home. Import USDZ models, preview them and replace suitable items with your own models. On a supported iPhone, capture an individual object from several angles to create its 3D model. A regular room scan identifies furniture; it does not create an exact photographic replica. Open the home on Mac to arrange catalog furniture and edit position, dimensions, rotation and finish. The catalog includes living room, bedroom, kitchen and bathroom furniture, decor, TVs and smart speakers. TVs and speakers are objects placed in the home model. CONNECT AND SAVE On iPhone and iPad, choose Apple Home, SprutHub or Home Assistant. Devices must be set up in your chosen system, with the required permissions. Available features depend on the provider and device. Save your home to a file and keep a backup in your own iCloud. LiDAR is required for room scanning, but not for controlling connected devices. Smart Home 3D is an independent app. Its lighting illustrates device states and is not an engineering lighting calculation. ACCESS AND PAYMENT The app is free to download. New subscribers receive 7 days of full access after confirming a subscription in the App Store. Your chosen monthly or yearly plan then applies; the price for your country is shown before confirmation. Cancel in your Apple settings. Customers who bought paid version 1.0 retain lifetime full access. Without a subscription, rotate the demo home and switch its lights, view your saved home and export it. Scanning, editing and commands to your devices require full access. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
