Digital catalogue apps
Live collections with weights, prices and availability; buyers filter, save and send selections — replacing PDF and WhatsApp catalogues that go out of date the day they are sent.
Your collection, in their pocket
Wholesale buyers want to browse and reorder without waiting for a PDF. Salespeople need the live catalogue on a tablet. Loyal customers want their scheme, wishlist and appointments in one place. We design and build iOS and Android apps for each of those jobs.
The short version
An app only earns its place if people open it every week.
We do not build apps for the sake of having one. We start with who will use it — a retailer reordering bestsellers, a salesperson at a trade show, a customer paying a monthly scheme — and build the smallest app that makes that job faster than WhatsApp and PDFs.
Apps connect to the same product data as your website and inventory, so prices, stock and photos are always current.

Questions
Mobile Apps, answered
Still unclear on something? Ask us directly — we would rather answer than guess.
info@rankoptim.comFor most retail customers, a fast mobile website is enough and we will say so. Apps make sense for repeat users: wholesale buyers, sales teams, scheme customers and loyal clients.
Yes. We connect to Shopify, your ERP or a custom backend so products, prices and stock stay in sync.
Usually both, from one codebase. B2B and staff apps can also run as installable web apps if store distribution is not needed.
You do — code, store accounts and data.
