According to Page Insights & Lighthouse its speeded up mobile browsing by quite a lot & a little on desktop speed. Tested before & after and I can see the difference on CLS. It'll take time to see if its made any difference on search rankings. Made no difference to the shopify speed though.

Great app that's easy to use. Took me no more than 15min to minify my code and my page speed score went up by 10 points! Thanks guys! And the fact that it's only a once-off payment makes it 10 times greater. Would highly recommend it!

— Sage & Sunday

WOW! Page speed seems to load 2 seconds FAST and optimized! This is a must-have app. I will recommend it definitely!

— Outdoorlee

Optimized our Page Speed up to 25% less time. The way to minify and publish the theme should be done better. I've to minify the theme manually with every single file and a single click.

Found this app and i really love the fact that you only pay once instead of all those monlthy fees everbody is asking. immediatly improved my lighthouse score performance with 5%. Deffinalty worth the 25 usd.

This app does minify CSS and JS successfully, and support is great! I had a bigger problem that was slowing down my shop, so I had to fix some things manually. This app though does exactly what it says, and for a lot less money than competitive apps. So, if bulky JS and CSS are your problems, this is probably the best you can get.

— Dreamframer Art

Great app and very helpful team! Chris even helped fix an issue which appears to have been unrelated!

What an amazing app, so easy to install and work with. Support is very responsive and the app as saved me on file sizes and our site now load much much faster. I can not recommend this app enough, it's truly a must-have app.

— The Fashion Gift Shop

— Goody Goody Gum Drops

super straightforward and easy to use. Helped reduce the size of my files + good customer support as well.

— Eucaly

Pricing system is deceptive. I paid $25.99, $39.99, $59.99 and still did not get all my files minified. If you do not know how many files need to minified and purchase the wrong plan you can purchase three plans and still not have the required results. I purchased the $25.99 when it did not do all of the files, I purchased the $39.99 still not enough. Finally I purchased the $59.99 plan. Sti...

WORST APP EVER WE EVER ADDED LOSED OVER 10 SPEED PTS INSTEAD OF EARNED SOME FELT LIKE CARELESS SUPPORT TOO BAD WE CANT ADD ATTACHED PIC WOULD AS BEEN FASTER TO SHOW SO WILL QUOTE " Hello I think the application does not really work. The application has not improved our speed. If I don't see its usefulness, I will remove it. Can you help me? Br, " ANSWER MADE " Hi , Thank you for reaching...

— Manège épicé

This app did just improve mobile speed slightly but not that we could say the score is really good (from 20 to 30 google pagespeed insights) and in fact decreased pagespeed on desktop even more (from 85 to 68). There was only option for optimizing css and no option for js or liquids.

— treeletic

We purchased the app and I followed the steps to duplicate the theme etc. When we went to view the duplicated theme, we got a 404 error. I've emailed three times without any response. I'm hoping I'll get a response here, if so I'll amend the review accordingly if it works as described.

— Dope Skin Co

After buying full version, My store became more slower than before and got a Grade F I contacted the developer and after checking, He told me "our app did its job" at least he didn't check the theme copy before installing that useless thing. I Don't recommend absolutely. Return my money back.

— Yousweety
