BT/BLE Scanner vs JWT Lens

Bluetooth Scanner turns your iPhone into a Bluetooth Low Energy explorer. Scan the environment, save the devices you care about, and inspect everything they broadcast — right down to the raw advertisement data. No cloud, no account, no internet connection needed: everything happens locally, straight from your device's Bluetooth hardware. FEATURES • Live scan of nearby Bluetooth LE devices, sorted by signal strength • Save devices to your list and give them your own nicknames • Swipe to remove a saved device at any time • Full detail view per device: signal strength (RSSI), TX power, MTU, connectable state, service UUIDs, manufacturer data, and more • Automatic background refresh keeps saved devices' signal strength and data up to date while you're on the Home screen • On-demand decoding of common BLE beacon formats — iBeacon, Eddystone, and Apple Continuity — shown as readable fields instead of raw hex • Export your saved device list as a JSON file via the share sheet • Scan preferences: auto-stop timer, hide unnamed devices, minimum signal strength filter — all remembered between launches • Dark mode by default, with a light mode toggle — your choice is remembered too • Fully offline operation, no tracking, no analytics PRIVACY Bluetooth Scanner does not collect, transmit, or store any data outside your device. Scanned and saved devices exist only for your current session; only your display preferences (theme and scan filters) are remembered locally on your device.

JWT Lens is a fast, private JSON Web Token decoder and verifier for developers — a Safari extension that works entirely on your device. Tap the toolbar icon, paste a token (or grab the text you've selected on the page), and instantly see: • Pretty-printed, color-coded Header and Payload • Human-readable timestamps — exp, iat and nbf shown in your local time with relative phrasing ("expires in 59 minutes") • An at-a-glance expiry badge: valid, expired, or not yet valid • Plain-English descriptions of standard claims (iss, sub, aud, and more) Need to check a signature? JWT Lens verifies HS256/384/512, RS256/384/512, PS256/384/512 and ES256/384/512 using a secret or PEM public key you provide — all computed locally with the system's WebCrypto, never sent anywhere. Privacy by design: • No network requests — ever • No analytics, no tracking, no accounts • Nothing is stored: tokens and keys live only in the popup while you use it Whether you're debugging OAuth / OIDC flows, inspecting a bearer token, or learning how JWTs work, JWT Lens keeps it quick, clear, and completely on-device. Universal app: works in Safari on macOS, iOS and iPadOS.
