A mobile-order flow that respects the morning ritual — seven taps to caffeine or it's a failure.
Starbucks Mobile Order & Pay runs across 35,000+ stores and handles 26% of all in-store orders. The existing flow had grown feature by feature into a seven-screen maze. I led the redesign with one non-negotiable KPI: time from app open to order placed must stay under 20 seconds for a known drink.
A Starbucks order is a customization bomb — dairy, temp, flavor, foam, drizzle, topping. The old flow exposed every option as a modal on a separate screen. For a regular ordering "the usual," it felt like paperwork. For a first-timer trying to build a venti oat milk iced vanilla latte, it felt like a customs form.
We needed to serve both users — the regular and the newcomer — in the same flow, without making either one feel like the design was for the other.
Approach
Favorites-first homeHome screen leads with your three most-ordered drinks as one-tap reorder cards. 60% of daily orders are reorders; the interface now acknowledges that reality.
Drink builder as single screenReplaced five customization modals with one scrollable drink-builder screen. Every option visible; nothing hidden behind a tap.
Store capacity indicatorEach store card shows live capacity — "Ready in 3 min," "Busy, 9 min wait." Ordering decisions shifted toward less-crowded stores, balancing partner load.
Pickup-time expectationAfter order placement, a live ETA with barista progress — "Drink started," "Drink finished," "Ready for pickup." Cut "is it ready?" anxiety, which was the #1 complaint.
Rewards inline, not separateStars accrued show as a tiny meter under the order total. No more "did I claim a free drink?" confusion.
