    The Challenge

    RU LINK sells more than a business card. Its range includes NFC cards, QR-printed T-shirts, Google Review stands for shops and restaurants, and custom products for brands, events and universities. Every one of them needs to point at a profile the owner controls. So the app is the control centre for the whole business: it creates personal, business and event profiles, links each physical product to the right profile, and lets owners manage products after they're sold, including one that gets lost. It had to work the same on iPhone and Android, sign people in quickly, and keep shipping improvements after launch without breaking the products already in customers' hands.

    The Solution

    What the app does

    • Profiles for every use. Personal, business and event profiles with a photo, contact details, social platforms and custom links, reordered and switched on or off individually, with a live preview of what people will see.
    • Direct mode. A switch on the profile changes what a tap opens: the full profile, or one chosen link.
    • Device management. Each card, stand or T-shirt shows up under Devices with its ID. Owners activate new ones, switch them on or off, mark one as lost, or buy more from the app.
    • Share by NFC or QR. Tap a RU LINK product or show a QR code linked to a short rulink/username address. Images and files can be attached for NFC sharing.
    • Connections. People, contacts, groups and connection requests, with search by name or company and discovery of RU LINK users nearby.
    • Quick sign-in and notifications. Sign in with Apple or Google, plus push notification preferences the user controls.

    Overseeing development

    • Turned the client's product range into a scope and milestones for the Flutter build, so profiles, device linking, connections and sharing could be checked and signed off one at a time.
    • Reviewed builds against that scope, with most attention on the flows the business depends on: activating a product, linking it to the right profile, Direct mode and lost-device handling.
    • Kept the app, the custom API and admin panel, and the product catalogue consistent, so every product the client sells is something the app can activate and manage.
    • Checked store-review requirements during development rather than at submission, such as offering Sign in with Apple alongside Google sign-in.

    Store listings, launch and updates

    • Prepared the App Store and Google Play listings: name and subtitle ("Stay Linked. Stay Ahead"), description, category (Productivity), age rating and the privacy policy link.
    • Took version 1.0 through review to launch in October 2025.
    • Managed the release cycle since then: five updates through 1.0.5 in August 2026, each one through review on both stores.

    Decisions & Trade-offs

    • Flutter for both platforms. One codebase keeps product activation, sharing and connections the same on iPhone and Android, and lets one team ship both store builds.
    • The client's own API and admin panel. Profiles, products and orders live on infrastructure RU LINK controls, which suits a business that sells hardware and takes custom orders. The cost is more backend to build and run.
    • Products are managed, not just linked. Devices can be switched off or marked as lost from the app, so a lost card doesn't keep sharing someone's details.
    • QR next to NFC. T-shirts and stands rely on QR codes, and not every phone reads NFC, so every product works with a scan as well as a tap.
    • Small, frequent updates. Five releases in ten months, each a small change, instead of one big redesign. That's less risk for customers whose products are already out there.

    Results

    • Live on the App Store (iPhone, iOS 15.5+, also runs on Apple Silicon Macs and Apple Vision Pro) and Google Play.
    • Six releases so far, from 1.0 in October 2025 to 1.0.5 in August 2026.
    • Free to download and rated 4+. One app manages every RU LINK product, from cards to T-shirts to Google Review stands.

    Impact

    When an app is the control centre for physical products, launching it is only the start. Every card or stand a customer owns depends on it working after each update. RU LINK is that longer job: keeping the build tied to the product range, and shipping it through store review again and again without breaking what people already have.
