What should a pet app in the GCC actually do?

Three things and rarely more: get someone back to the thing they were looking at, make reordering faster than opening a browser, and tell them something worth being told. Everything else is a website in a shell.

What earns its place on a home screen

The feature list is not what decides installs. What decides them is whether the app removes a step the mobile site made you take — signing in, re-finding, re-entering an address.

An app earns its place through repeat purchases and notifications, so the question is really about how often somebody buys. For a pet supplies store in the GCC, the answer turns on one thing in particular: Pet food is the most reliably repeated purchase in retail: the bag runs out on a known schedule.

What is different about the GCC

The GCC is not one market. Payment habits, delivery norms and language expectations differ enough that a single approach underperforms in at least one country.

Payment preference varies by country more than most planning assumes.

What is different about a pet supplies store

Built too early it is a cost with nothing to do — an app with no customers to bring back is a bookmark nobody made.

Where a mobile app comes into it

This is the clearest case for an app of any category. TicApp built barcode reordering into Pets Lounge for exactly this.
