mDNS Browser helps you discover Bonjour, DNS SD (DNS Service Discovery), and common Avahi-advertised services on your local network. What you can do • Browse by service type, with useful presets and custom types • See IPv4 and IPv6 together, and filter what matters to you • Quick filter across instance name, hostname, type, addresses, and TXT records • Sort results so large scans stay manageable • Open a detail view, copy IPs and TXT lines, and run TCP or UDP reachability checks (chosen automatically from the service type) • Open HTTP or HTTPS in the system browser when a service resolves to a usable URL Privacy • Discovery runs on your LAN; the app is not designed to upload your scan results to our servers (there is no account system in the app). Notes • Whether a service appears depends on it actually advertising on the current network, and on multicast not being blocked by routers, VLANs, or firewalls. • Some services bind only to certain interfaces or subnets and may be invisible from other devices. Turn noisy LAN discovery into a clear, filterable, verifiable dashboard.

Ever wondered what an app actually learns about you the second you open it? Privacy Scanner reads your own iPhone with the exact same public Apple APIs every other app already has — and shows you the raw values, in plain language, one signal at a time. Most privacy apps tell you what could happen. This one shows you what IS happening, on your device, right now. Every reading is taken live from your phone, sorted into three honesty levels — Passive (read silently, no prompt), Permission-based (read after you tap Allow), and Advanced (legal-but-sneaky tricks) — and each row explains exactly what that value reveals to a tracker. WHAT YOU GET - A live scan of 30+ silent signals — model, screen pixels, RAM, storage, uptime, battery, locale, timezone, accessibility toggles, network type — that any app reads without asking you once - Your device fingerprint as a single SHA-256 hash, plus the explanation of why those few stable details are enough to single you out with no login and no shared ID - Proof of what "Allow" really hands over: the exact number of contacts, photos, calendar events and reminder lists readable, and your precise GPS coordinates to five decimal places - The advanced tricks exposed: a silent probe showing which of 24 popular apps you have installed, a Keychain identity that survives deleting the app, and whether your clipboard is readable right now - A plain-English "what this reveals" write-up on every single signal, so you understand the risk instead of just seeing a number - A full exposure report you can share or save yourself, plus one daily reminder to re-scan at the hour you choose PERFECT FOR - Anyone who suspects apps know more about them than they were told - Privacy-minded people who want evidence, not vague reassurance - Students, journalists and researchers learning how device fingerprinting actually works - Parents and teachers explaining digital privacy with something real on screen WHY NOT JUST CHECK IOS SETTINGS? Settings shows you the permissions you granted. It says nothing about the dozens of values apps read with no permission at all — the model, the screen, the timezone, the accessibility toggles, the installed-app probe, the Keychain ID that outlives a reinstall. That invisible layer is where fingerprinting lives, and it is the layer this app was built to show you. PRIVACY 100% on-device. There are no servers, no analytics, no advertising identifier used by us and no third-party SDKs. Nothing you see is uploaded, ever. Your exposure report leaves your iPhone only if you tap Share yourself, and only to where you send it. FULL ACCESS Full access unlocks the entire scanner: all three exposure levels, the complete signal list with every explanation, the SHA-256 fingerprint screen and the shareable exposure report. Pick the plan that suits you — Weekly, Yearly, or a one-time Lifetime unlock. Weekly and Yearly renew automatically until cancelled in your Apple account settings; Lifetime is a single payment with no renewal. Open the app and run your first scan — in under a minute you will see the exact fingerprint your iPhone hands out to every app you install.
