The app does a more measurable progress on mobile download speed increasing First Contentful Paint which was around 3.4 s on a collection page, now app installed it is about 1.3 s. Overall our Google Pagespeed score increased around 5 - 8 points for the same collection page.

A quick and easy way that made our site snappier with first visits and slower connections where the browser needs to initial cache. This did not make lighthouse faster for us, perhaps a misconception of what critical CSS does, but it does make real world load time faster and lowered our blocking time.

Thanks for your review. I'm sorry you were unhappy with the app. We did swap a few emails and I explained the limitations of the app, but if you're still unhappy, I'm happy to refund you the $10.

This has to to the best app in the shopify apps store to help you be successful. I will admit I am using FLEX so I had really good page load but with Critical CSS 1.32 sec loading time. Never been able to achieve that with many attempts with other themes. I think I have the right combo now. Thank you!

"Instant pagespeed increase for $10... yeah right?!" That's exactly what I said when I saw this app but thought I'd give it a go anyway, SO GLAD I DID! Having spent a few days trying to boost the speed of our store and only getting marginal gains my research lead me to this app. The install was super easy and instantly flagged up some unseen errors in my CSS (blame my template creators for that!), once I fixed those the app did its thing and added a snippet to the head for the critical css, I could then confidently move all the remaining stuff to the end of the body. I ran a pagespeed test before installation on the different page types and again after installation (plus cache clearing). I'm happy to report a very significant pagespeed increase across all pages! I had a few noob questions and the support was spot on and helpful. Honestly, this is a seriously good value for money app and really worth trying!

One day since install opinion: This helps us stream line our CSS and in conjunction with some other fixes we were able to get our page speed score up from a 28 to a 90(at its peak on mobile)! Great customer service, alex responding quickly and was ready to help however we needed. This is a one man team and he's doing great job!

I've run all possible tests while trying to change everything manually to get the site to run smoother and the changes were minor. After installing the app the performance scores went up by a LOT. Especially mobile scores. Thank you for the great app.
