Check 6 / 12 LOW impact In the full checklist
Limit Shopify apps <6, audit with Theme Analyzer
What this check is
Apps accumulate, and each one adds scripts, styles and sometimes its own version of a library already loaded. Keeping the active set small is a maintenance rule as much as a performance one.
How to implement it
Audit the installed apps against the ones actually used in the last month, cap the active set at what you can name, and run the theme performance audit tool in Shopify to see which app code is injected where. Replace overlapping apps with one that does the job.
How to verify it
Run the theme app audit and the mobile speed test after the cleanup, and record the installed app count and the total blocking time before and after.
