The release that set the table.
Before 4.0 made the store personal, 3.7 gave it reach and reflexes: the last markets in Apple's global retail coverage, and the first retail use of 3D Touch. I owned the 3.7 roadmap and release.

Press to peek. Press again to buy.
The first retail implementation of 3D Touch. A light press previews a product without leaving the shelf; a deeper press favorites it or drops it in the bag. Tuned to a sub-100ms response, so pressure felt like a shortcut, not a wait.

Every market, complete.
Thailand, Korea, and Russia closed the last gaps in Apple's global retail app coverage, each with local payment methods, localization, and the regulatory work its market required. With 3.7, the app reached every Apple Online Store geo in the world.
Your pickup, in Wallet.
Reserve online and the pickup pass lands in Wallet, then surfaces on the lock screen the moment you reach the store. The order waiting at the counter, one glance away.

Favorites, on your wrist.
Favorites expanded to every product, then followed you onto Apple Watch, so a saved item and a price alert were one glance away.

What 3.7 shipped.
The features that moved 3.7 from a catalog toward the ecosystem-aware app 4.0 would become. All good work is the ensemble of a team.
What I owned.
I owned the 3.7 roadmap and release, focused on the features that only made sense on iOS: the first retail use of 3D Touch, the international work that completed Apple's global retail coverage, and the Wallet and Favorites infrastructure the next release would build on. The interaction research and international groundwork from 3.7 fed directly into the personalization work in 4.0.

Global scale you can build on, and a pressure-sensitive interaction users already understood. 3.7 is the release that made 4.0 possible.
