Sentry

Read full description

A room-scanning aid for your phone. Hidden cameras get concealed in everyday objects — smoke detectors, USB chargers, alarm clocks, vents and mirrors. Sentry uses the sensors already in your phone to measure five different signals in a room and shows you every reading, so you know which spots are worth inspecting by hand. Sentry does not identify cameras. It measures signals — infrared light, magnetic fields, bright reflections, and the devices on the network around you — and each of those signals can come from ordinary electronics just as easily as from a camera. No app, and no dedicated hardware, can find every hidden camera. Sentry is a tool that guides a careful manual check; it is not a guarantee and should never be treated as one. WHAT SENTRY MEASURES • Infrared (IR) Scan — your camera sensor can show infrared light, the kind night-vision cameras emit in the dark (as do remotes and many sensors) • Magnetic Field — reads spikes near powered electronics, including devices with no Wi-Fi • Lens Reflection Scan — on-device image analysis flags bright, lens-like glare for you to look at • Wi-Fi Network Audit — lists devices on the network you're joined to and flags names matching known camera brands • Bluetooth Scan — lists nearby advertising devices with an estimated distance HOW TO USE IT 1. Tap Scan and pan your phone slowly around the room 2. Watch the live readings — a glow, a highlighted box or a signal spike 3. Go to each flagged spot and inspect it with your own eyes and hands The third step is the important one. Sentry tells you where to look; it cannot tell you what is there. BUILT PRIVATE Sentry works entirely on your device. No account. No uploads. No tracking. Your scans and any photos you save never leave your phone. WHO IT'S FOR • Travelers in hotels, motels and Airbnbs • Renters checking a new place • Changing rooms, fitting rooms and restrooms • Meeting rooms and private offices SENTRY PRO Sentry Pro unlocks all 5 scan methods, unlimited full-room guided sweeps, and a private scan history.

About

PasswordMe

Features
Read full description

Some sites reject every password you try. Too long. Wrong symbol. Must start with a letter. PasswordMe builds one that fits their rules on the first try. Tap once for a strong random password, or set the exact recipe a site demands: length, how many uppercase, lowercase, numbers and symbols, which symbols are allowed, what it can start or end with, no repeats, no sequences, no keyboard patterns. PasswordMe checks the rules for conflicts before it generates, so you never paste a password that gets bounced. PASSWORDS THAT FIT THE FORM • Any length from 4 to 256 characters • Exact uppercase, lowercase, number and symbol counts • Choose the allowed symbols, or remove look-alike characters • Start, end, repeat, sequence and keyboard-pattern rules • Conflict checks before you generate WHEN AUTOFILL ISN'T ENOUGH • Wi-Fi and router passwords you have to type on another device • PINs and door codes without the obvious patterns • Smart TVs, consoles and anything you enter with a remote • Work systems and legacy sites with strict, unusual policies • Passwords you have to read out loud or write down MORE WAYS TO GENERATE • Memorable passphrases from real words, English or Spanish • Pronounceable passwords that are easy to type and say • PINs and numeric codes, checked against common patterns • Memory Phrase turns your own cue into a strong password • Batches of unique credentials in one go • Presets save the recipe, never the password itself PRIVATE BY DESIGN Every password is created on your device and keeps working with no connection. There is no account and nothing to sign up for. Password and phrase content never goes into analytics, logs or ad requests. Clipboard entries expire on a timer you choose, the app hides its contents in the app switcher, and optional history is encrypted and locked behind Face ID, Touch ID or your passcode. FREE TO START Passwords, exact-rule results, passphrases, PINs, pronounceable passwords and small batches are all free. PasswordMe Pro is a one-time purchase, never a subscription. It removes ads and unlocks unlimited presets, up to five results at a time, batches of up to 1,000 and encrypted history. PasswordMe is a password generator, not a password manager. It makes the password; you keep it wherever you already store yours. Questions or a rule we don't handle yet? Write to support@navirialabs.com and we'll take a look.
