iOS + Android mobile app

Mart-Club is a hybrid mobile app for Android and iOS that aggregates promotions from over 25 Dutch retailers — including Kruidvat, Etos, and Bol.com — into a single, easy-to-use experience.

Users can compare prices, scan barcodes, and build a favorites list with push notifications for new deals. On average, users save €396 per year on cosmetics and personal care products.

We designed and built Mart-Club from the ground up, handling architecture, backend infrastructure, UI/UX design, and integration with dozens of retail data sources.

The challenge

The Dutch beauty and personal care market is crowded with retailers, each running its own promotions, loyalty schemes, and seasonal campaigns.

1.

For consumers, tracking the best price means checking multiple websites, flipping through flyers, and comparing manually.

2.

Aggregating data from 25+ retailers with different formats and update cycles — and reliably matching the same product across stores.

3.

Sending personalized deal alerts in real time, and making it all feel fast and native on both platforms.

Our solution

We built a full retailer integration engine, product matching system, personalized alerts, barcode scanner and a clean mobile UX.

React NativeiOSAndroidBackend integrations

A modular backend connects to 25+ retailers, normalizes product and pricing data into a unified format, and stays current. Adding a new retailer means plugging in an adapter — not rebuilding the pipeline.

A matching algorithm identifies the same product across different retailer listings, and the notification system fires a push notification the moment a favorite goes on sale. The barcode scanner lets users scan any product in-store and instantly see prices across retailers.

Results

Mart-Club is live on both the App Store and Google Play, serving a growing community of deal-savvy shoppers.

€396 average annual savings per user.

25+ retailers integrated, from drugstores to premium beauty webshops.

Hundreds of brands covered — L'Oréal, Estée Lauder, MAC, NARS, Olaplex, Kérastase, and more.

Scalable architecture lets the client onboard new retailers without rebuilding the system.

Dextrasoft built the Mart-Club app from scratch and delivered exactly what we envisioned. The app is fast, intuitive and our users love it. Since launching, our community has grown exponentially. The team was proactive throughout the entire process and always came with suggestions we had not even thought of ourselves.
