Case Study: Building Wishme, a Shopify Wishlist App

Most of our writing is about client work. This one is about our own product, because building for the Shopify App Store teaches lessons that client projects rarely do: you own the roadmap, you feel the support load, and you live with every shortcut you take.

Wishme is a wishlist app for Shopify storefronts. Here is how we thought about it, what we built, and what we would do differently.

The problem: interest without intent

There is a gap in most shopping journeys. A shopper finds a product they like but is not ready to buy. Perhaps the price is a stretch this month, perhaps they are comparing three options, perhaps they are buying for someone else and need to check a size.

Right now, that interest goes nowhere useful. It becomes an open browser tab, a screenshot, or nothing at all. The shopper leaves, and the store has no way to bring them back to the exact thing they were considering.

That is a solvable problem. The save-for-later moment is familiar from nearly every other shopping context. What was missing was a version that felt native to a Shopify storefront rather than bolted on.

Why a wishlist, and why Shopify

We chose Shopify deliberately. It is where the merchants we work with already are, it handles the commerce primitives, and its app ecosystem gave us a real distribution path rather than a cold-start problem.

A wishlist is also a good product for a small team to own. The scope is bounded, the value is legible, and success or failure is visible in a handful of metrics.

Designing the save moment

The single most important decision was where the action lives. The lazy version of a wishlist app adds a dedicated wishlist page and a heart icon somewhere in the header. Shoppers then have to remember it exists.

We treated saving as a moment, not a destination:

• The save control belongs on the product card and the product page, exactly where interest occurs.
• Feedback has to be immediate, because a save with no confirmation feels like it failed.
• The return path matters as much as the save itself. A shopper who saved something should be able to get back to it without hunting.

How it is built

Wishme is a Shopify app, which shapes the architecture:

• An embedded admin experience for merchants, so setup happens inside Shopify rather than a separate dashboard.
• Theme app extensions for the storefront, so the save controls fit the merchant's theme instead of fighting it.
• Storefront APIs and the customer account model, so a shopper's list follows them rather than living in local storage.
• Webhooks for the events that need to stay in sync.

The design constraint throughout was restraint. Every merchant's theme is different, so the app has to look at home in all of them.

What we got wrong first

Two things, mainly.

We over-built the admin. The first version gave merchants more configuration than most of them wanted. New users do not want options; they want it working. We moved sensible defaults to the front and pushed depth behind them.

We under-invested in empty states. An empty wishlist is a shopper's first impression, and we treated it as an edge case. It deserved designed guidance, not a blank page.

What we learned

• Distribution is a product feature. Building for an app store means the listing, screenshots, and reviews are part of the product, not marketing afterthoughts.
• Restraint travels well. Code that does less but fits everywhere beats code that does more and fits one theme.
• Support is a design signal. Repeated questions are not a support problem; they are a design problem you have not fixed yet.
• Owning the roadmap sharpens judgment. Deciding what not to build is easier when you live with the consequences.

What this means for client work

The product experience changed how we approach custom builds. We are quicker to trim configuration, faster to ship a default that works, and more careful about empty and error states, because we have felt what happens when they are neglected.

If your store needs app functionality that does not exist off the shelf, that is exactly the kind of private app we build. Read more on our Shopify services, see Wishme, or tell us what you need.
