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.

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.

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!

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.

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.
