This app is a sales tactic to charge hundreds of dollars to fix speed issues, without providing any information on how to actually do that without paying a fee for them to do it for you. No tutorials, recommendations on how to implement - nothing but a quote. You should not be allowed to offer an app that isn't a functioning app but instead a sales ploy to lure in customers. Shopify store owners beware.
The app provided a detailed speed report for my shop. I found a few useful insights which weren't mentioned in Google Pagespeed. Though, it would be great if this app not only made an audit but also offered automatic speed optimization.
