A self‑directed teardown of the Instacart mobile app examines the business model and product decisions that shape the shopping experience, and identifies where and how that experience breaks.
Instacart runs one of North America's largest grocery marketplaces but owns no stores, no inventory, no supply chain. It makes money on access and advertising, not groceries. The tradeoff: it can't control the two things customers care about most the final price, and whether they get what they ordered.
This teardown walks the app step by step and finds the sharpest break at the shelf: substitutions. When an item is out of stock, a shopper swaps it often without the customer's context. That one moment decides whether they trust the basket and come back.
The project ends with one focused opportunity: Turn substitution of a product from friction into building user's trust.

"Grocery runs on low single‑digit retail margins, and thin economics per order are the structural reason that basket size (not order count alone) drives the business"

04 · Ecosystem overview
Auditing Instacart's product understanding, user interface, and experience
Instacart's mobile app UI is clean, visually rich, and easy to navigate for both new and returning users. The user flow does a good job of making a huge multi-retailer catalog feel browsable, but that surface carries a lot of promotional weight, and the one thing customers care about most, the true all-in price, is the least visible element on screen.

(with design-decision analysis)
The feature set is broad and the core flow is competent. The interesting question for a teardown is not whether Instacart works, but where the design earns trust and where it leaks it.
