What makes a Shopify app worth adding?

One question kept coming up while I was building StackFit: where should a merchant draw the line between a genuinely useful Shopify app and another subscription, dashboard and implementation job?

When you assess an app, what matters most?

• Revenue opportunity

• Time saved

• Integration quality

• Setup and maintenance work

• Cost as the store grows

• Something else entirely

I’m particularly interested in apps that looked promising but were installed too early, or tools you later removed because they duplicated something already in the stack.

I’m using this launch to learn where StackFit’s recommendations could become more useful, so honest examples are very welcome.
