How to spot two Shopify apps doing the same job

List what each app actually does on the storefront, not what its marketing page claims. When two apps inject scripts for reviews, popups, or upsells on the same pages, you are paying twice for one job and slowing the store for it.

Compare installed behavior, not feature lists

Open the storefront and note which apps render on product pages, the cart, and checkout. Marketing pages describe aspirations; the rendered page shows the truth. Overlaps show up fast: two review widgets, two popup tools, an upsell app plus a theme feature doing the same thing. Write down each app and the pages where it actually runs.

One script per job

Two review widgets means two script payloads on every product page. Keep the one that converts better, remove the other, and retest speed before and after. Merchants are often surprised how much of their JavaScript weight comes from a duplicated job rather than a necessary one. The removal test is cheap and the result is immediate.

Audit on a schedule

Apps accumulate because nobody removes them. A twenty-minute review every few months keeps the stack honest: list installed apps, flag anything unused in the last quarter, check for overlaps, and uninstall with a backup of settings. Lean is not a one-time project. It is a habit.

Check the overlap on the invoice too

Redundant apps cost money twice: once in performance, once in subscription fees. Pull up the app invoices for the last quarter and match each charge to a job on your list. Apps nobody can name a job for are the easiest cuts. Merchants often find they are paying for two or three tools that all promised to solve the same problem, installed months apart and never reconciled. Canceling the losers is the fastest return on a stack audit.
