The situation: A beauty brand's loyal customers reordered often but through slow mobile web pages.
What we did:
Built a React Native app connected to Shopify
Added saved carts, Apple Pay and Google Pay
Set up back-in-stock and replenishment notifications
The result: App customers ordered more frequently, and reorder reminders drove a steady share of revenue.
