Checked into a hotel, an Airbnb or a rental and want to be sure nobody is watching? Room Check walks you through the room step by step and keeps a record of what you found. ROOM-BY-ROOM CHECK Pick the place - hotel room, rental, changing room, office - and the rooms you want to check. For each room you get a short list of the spots where small cameras are really hidden: smoke detectors facing the bed, USB chargers, clocks, frames, vents, mirrors. Tick them off as you go. LENS FINDER Turn the lights off and sweep the room with your phone. The flashlight makes camera lenses reflect as tiny, sharp dots; Room Check marks reflections that stay put while you move, so you know exactly where to look closer. WI-FI DEVICES See every device on the Wi-Fi you're connected to. Room Check checks which ones stream video (RTSP), expose camera ports or show a camera web panel, and tells you why each device was flagged - no vague "suspicious" labels. BLUETOOTH NEARBY Spot trackers and unnamed devices around you, then follow the signal with the warmer/colder locator until you're standing next to it. MAGNETIC SWEEP Calibrate, then move your phone along objects. A jump in the magnetic field inside something that shouldn't contain electronics is worth a closer look. PDF REPORT Photos, findings, the checklist and the network list go into a dated PDF you can send to the host, the landlord or the booking platform. PRIVATE BY DESIGN No account. No tracking SDKs. Scans, photos and reports stay on your phone. HONEST LIMITS Room Check helps you decide where to look - it can't guarantee a room is free of recording devices. Cameras on another network or recording to a memory card won't show up in a Wi-Fi scan; covered lenses may not reflect. If you find something, don't touch it, take photos and contact the host, the platform or the police. Room Check Premium Every tool can be used once for free. Premium unlocks unlimited scans, room checks and PDF reports. Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in Settings > Apple ID > Subscriptions.
