Okay this app is MAGIC I SWEAR. I was about to hire someone to work on my website because my page speed score was really low for mobile. 81 for Desktop and 30 for mobile. I downloaded this app, edited the code and within seconds my speeds went to 97 on desktop and 63 on mobile!!! You guys are life savers!!! Any one looking for help with page speed THIS IS YOUR APP!

Thank you for the super cool review.

Since speed improvements vary store to store based on a variety of factors we normally cannot predict.

However your mobile speed improvements even amazed us - from 30+ to 70+ is a record improvement for us too. Glad to have you as a customer

This is one of the best solutions we came across for increasing our Shopify store speed. The app skyrocketed our store speed from 25 to 75+ for desktop and 11 to 44+ for mobile instantly after installation. Superb app and great work

Update: this app unfortunately didn't work together with another essential app we are using. It looks like it deletes some JS unused which potentially slows the website. But these are many times used offline by other apps. Nice developers though, give them a shot, it might work with your settings. Initial comment before these issues:
Great app, it does improve the download speeds. A few issues are resolved by the developer. The developer disclosed that technically Swish app improves the loading mechanism of the resources which are causing speed issues. That is so true, verified by GTmetrix the resources such as page sizes and request counts are cut down almost to half. Wow!
