Every day the app tests your home page, a product page and a collection page on a phone with Google PageSpeed Insights, explains the results in plain English, and emails you when something makes the store slower.
Each page is tested twice and the middle result is shown, because single tests swing by several points. A 30-day chart shows the trend.
Outside scripts are grouped by the app or service behind them (reviews, chat, email pop-ups, ad pixels) with the time each one keeps the phone busy.
Google's suggestions turned into short sentences: files holding up the first screen, oversized images, unused JavaScript, lazy main images, too many fonts.
When Google has data from real Chrome users over the last 28 days, you see it next to the test, including whether the store passes Core Web Vitals.
An email when the home page score drops 10 points below its 7-day middle value, or the main content shows a second or more later. Plus an optional Monday summary.
The app never edits your theme or store. It needs one permission, read products, to pick a product and a collection page to test.
