Does not work in the theme by Out of the Sandbox. After turning on, all images disappeared, and when off they came back.

Support just blamed everyone else and didn't even have a look. First it was domain provider, then it was Shopify and then heavily optimised theme (it really isn't) - just guessing.

Hi there,
Bryan here from Booster Apps, I'm sorry for your experience using the app. I read through your conversation with our support team and we haven't had a scenario like this before happening with any theme. We would love to investigate and find out what could have caused the issue. We've reached out over on email as well to help us uncover this.
Looking forward to hearing from you.
Cheers,
Bryan.

Tested load speeds with pingdom and went from 5.61 seconds to 5.84. I am sure this works with some sites but it certainly doesnt work with all of them.

Hi there, thanks for the review. Unfortunately page speed apps such as pingdom or gtmetrix will not show any improvements when the app is installed. This is due to the fact that these apps measure page speed on first page load.. this app only starts working after first page load as we are preloading links on the page.. 😔
Cheers, Stuart

Hi there,

Pat here from Booster Apps Tier 2 Support.

Allow me to provide some clarification on how our app functions. Our App Page Speed Optimizer is specifically designed to improve the loading times of your store by adding a straightforward script tag, booster-page-speed-optimizer.js, to your theme.

This script optimizes your site's speed by pre-loading links, resulting in quicker navigation for your visitors.

Regarding the language selection, I apologize for any confusion caused, but please note that our app doesn't offer language selection as it primarily focuses on improving page speed performance by simply sliding the switch to the ON position and the app.

You can also check our FAQs for more information about the app.

Though our app is free, it is by no means at all an app that we neglect, and we take issues such as the one you're experiencing very seriously and would love to get to the bottom of the issue you're experiencing.

Would it be okay for us to collaborate with you to resolve the issue? I'll be happy to send over a collaborator's request and look further at what went wrong.

Happy to offer you any help you need here so we can turn your experience with the app around for you.

Cheers,
Pat

Hi there, thanks for taking the time to leave a review :) I'm afraid the app will not show any results whatsoever on page speed apps such as pingdom or gtmetrix.

This is due to the fact that these apps measure page speed on first page load.. this app only starts working after first page load as we are preloading links on the page...

Cheers, Stuart

Made the mobile speed worse. Didn't seem to impact Desktop. I recommend describing a bit more about what the *.js file does. I also recommend offering "tree-shaking" to get rid of unused CSS at the very least.

Hi there :) Please note this app will not increase or decrease any pageload speed metrics such as Pingdom or Gmetrix. The app preloads links, which only works from the second page view. These apps do not account for second page load times in their results. Cheers, Stuart

One click optimization, seemed easy enough. Increased my page load time in GTMetrix from 3.3 seconds to 5.7 seconds, and decreased my PageSpeed Insights (Google) scores from 43 Mobile / 86 Desktop to 33 Mobile / 70 Desktop. Not good!

My site's theme is a little bloated and I saw this app. The ONLY reason I gave it 2 stars is because their UX is so fun. It was simple and rewarded me with confetti for clicking a button! However, I cannot recommend this product as it actually lowered my site's score on Pingdom (75 to 74) and PageSpeed Insights (33 to 25). From what I can tell, it added .1 seconds to the load time.

I would love to love this product, but cannot. But their development team has done a great job with the UI so while I cannot justify using the app I genuinely enjoyed it for the brief time that I did.

I should also add, their response to this issue (slowing page load speed) is boilerplate and does not address the issue. If "page speed apps such as pingdom or gtmetrix will not show any improvements when the app is installed" then how do you recommend we gauge performance?

If this app does what it claims, how can we verify the results?

It made my store slower. I tested on google pagespeed insights before - scored 16. Installed and ran app, scored 14. The app does not make the page load faster.
