Pet tech web app · Australia · 2022 build

One URL.
Three apps. One QR code.

Recollo’s FOMO Pet Tags are QR codes you scan when a pet goes missing. Each tag’s URL serves three completely different experiences depending on who’s scanning and whether the tag is claimed — same address, three different apps.

The build

Three states,
one URL.

A single QR code on a physical pet tag links to one URL — but what loads depends entirely on context. Unregistered tag? Show the product. Authenticated owner? Show the management dashboard. Stranger holding a lost pet? Show owner contact info immediately, no login required.

Unclaimed tag flow

Visitor sees Recollo branding, product explanation, and a clean path to create an account or log in to claim the tag.

Owner claim & management

Authenticated owners enter pet details, photo, and emergency contact. Data stored against the tag’s unique ID in MySQL.

Finder mode, instant access

A stranger who finds a lost pet sees the pet’s name, photo, and owner contact details immediately — no account, no friction, just speed.

Privacy by design

Contact details only ever appear inside the finder view — never indexed, never publicly accessible outside the QR-code flow.

How it actually went

No tricks.
Just the right work, done properly.

01

The challenge

One QR code on a physical pet tag. Three completely different audiences who might scan it: a new owner about to claim, the existing owner managing the profile, or a stranger holding a lost pet. The same URL had to serve all three — instantly, with zero login friction for the finder.
02

The approach

WordPress as the CMS and admin layer. Custom PHP for the state-detection logic on every scan. MySQL storing tags, claims, and pet profiles against unique IDs. Mobile-first templates designed for the “I just found a pet on the street” moment, where every second matters.
03

The result

A single URL that behaves like three different apps depending on who scans it. The finder flow — the most time-sensitive part of the experience — works in seconds, on any phone. New tags scale infinitely: each one is just a new database record with its own generated QR code.
The actual work

What it took
to build it once.

From three-state logic to bulk tag inventory generation. The bones of a real web app — not just a website.

  • Owner dashboard for editing pet details & contact info
  • Photo upload & emergency contact handling
  • Privacy safeguards — finder details non-indexed
  • Bulk tag inventory generation for the business owner
  • Admin layer in WordPress for tag and claim management
  • Cross-browser mobile testing on iOS + Android
