Little Eye
Scan, paste, decode
Only for iPhone

iPhone
Little Eye tells you what you're actually looking at.
Paste in an IP address, a domain, a URL, a token, a timestamp, a color, a
barcode - share it straight from another app, type it in by hand, or scan a QR
code or NFC tag - and Little Eye instantly shows you what's inside. No handing
sensitive values to random websites. No context-switching to jwt.io, a WHOIS
site, an epoch converter, or an IP-lookup page.
Detection happens entirely on your device. The network is only ever touched when
you tap an action that clearly says so - a URL fetch, a DNS or WHOIS lookup.
Nothing is uploaded, there's no account, and there's no telemetry.
WHAT IT RECOGNIZES
• JWTs - algorithm, claims, and expiry, decoded offline
• JSON - pretty-printed and validated
• Base64, URL-encoding, hex, ROT13, Morse and more - decoded in place
• IP addresses - offline country geolocation, plus on-demand DNS and reverse DNS
• Domains & URLs - DNS, WHOIS/RDAP straight from the registry, HTTP details
• Timestamps - Unix epoch and ISO dates in human form
• Colors - hex and rgb swatches
• Barcodes & GTINs, IBANs, UUIDs, API keys, coordinates, and dozens more
SIX WAYS TO GET SOMETHING IN
• Paste - tap Paste and Little Eye reads it on the spot
• Share - send text or a link to Little Eye from Safari, Mail, Messages, or any
other app, right where you found it
• Type - enter a value by hand when it isn't on the clipboard
• Scan a barcode or QR code with the camera and see what it decodes to
• Scan an NFC tag to read the links and codes it carries
• Open a file from Files, or an image from Photos
Whichever way it arrives, you can drill down card by card - every result is the
starting point for the next one.
PRIVATE BY DESIGN
• Detection is local. The network is opt-in, per action, and clearly labelled.
• No account, no sign-in, no analytics, no tracking.
• When Little Eye does reach out, it asks the original source directly -
the DNS resolver, the domain registry, the host itself - instead of routing
your data through a third-party website.
LITTLE EYE PRO
A one-time purchase unlocks the network-powered features (DNS, WHOIS, reverse
DNS, URL fetch and more). Everything else - all offline decoding and detection -
is free, with a 14-day trial of the Pro features to start.
Built for backend developers, DevOps and platform engineers, security
professionals, and anyone who spends the day elbow-deep in tokens, links and
logs.

Bluetooth scanning, plus a fresh look.
New in 1.0.16
• Bluetooth: tap the new Bluetooth button to list nearby devices with their maker, signal strength and services. It's decoded on your iPhone and nothing is stored or uploaded. Bluetooth is a Pro feature.
• Identify a device to see which services it offers, its maker, model and battery level, and whether it's a known tracker (AirTag, Tile, Chipolo, Samsung SmartTag). For an AirTag you can also play a sound to find it.
• Choose which kinds of devices to identify, or turn on automatic identification after a scan.
• Filter the list by device type, search by name, maker or type, and sort by name, nearest, newest or type.
• A cleaner device list, with names that read better and more devices recognised, including Windows PCs and Nest alarms and thermostats.
• Little Eye now recognises vCard contact cards and calendar events (vCalendar/iCalendar).
New in 1.0.15
• A calmer dark palette with a violet accent, flat cards, bigger tap targets in the bottom bar, and a redesigned Type sheet.
• Updated the offline country database used for IP lookups (September 2026 snapshot).
