Does not work. My Shop does not even load anything since I have activated the App. The first time the support told me that the App is not compatible with my theme so I changed everything but also with the other theme the App does not work. Very frustrating.

Hi there,

I've read your recent feedback about our app, and I'm truly sorry to learn about the issue you're having with our app.

However, I would like to clarify that while our app works, it's just not the ultimate fix to speed up your store. It also doesn't directly increase your online speed test scores because of the way it works. However, it does significantly contribute to an improved browsing experience for your site's viewers and customers. Also, we have our 24/7 chat support team who are more than happy to help guide you on how to improve your store's speed.

However, I have sent you an email so we can continue the conversation and discuss how we can go about making things better for you.

We hope to hear back from you soon.

Sincerely,
Pat

There's no way to get a hold of the company and I need help. I'm getting website errors across every page and it looks like there’s uncompressed JavaScript files being served all from your app.

Can you enable compression?

Thanks

This app broke an automatic discount we created for a free bonus item. This killed countless orders. Our promo was for Father's Day, and customers got a free product once they spent $100 in our store. Sadly, this app, caused the cart not to mark the product free, forcing several customers to complain and bounce. As a speed plugin for an eCommerce platform, they didn't properly exclude the cart items from the cache, obviously, which is a rookie move. Sorry guys, I wish I could give you a better review, but you cost me sales.

Hi there,

Pat here from Booster Apps Tier 2 Support. I just saw your review and wanted to reach out to apologize for the trouble you had with our app. 😔

For clarification - the app automatically speeds up your store's load times by adding one simple script tag to your theme called booster-page-speed-optimizer.js. Page Speed Optimizer is made and designed to help boost the speed of your site in terms of clicks by pre-loading links.

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 what caused the issue that broke your automatic discounts.

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.

So sorry again for the hassle here. Please let me know if you have any questions.

Cheers,
Pat

Didn't see any increase in site speed. Not sure what the app actually did, but it didn't help. I guess it wasn't a bad test for free

All my images would NOT load after app install! Not worthy. I don't think I have any more words to explain as required by the program. Website worked perfect before app install, website would not load images after. And it wasn't the app?

Hi there,

Sorry to hear that you're experiencing this issue. I'm afraid this completely unrelated to the app :( Our app places a single line of javascript code to speed up your next page load - we do not have any access to editing or updating your images.

Cheers

It's a very bad app. When I install this app, this app effect the website is blank. The support team cannot help to fix it and just send me the general answer.

Hi Secret Sofa Team,

Aroll here from Booster Apps Tier 2 Support. I just saw your review and wanted to reach out to apologize for the trouble you had with our 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 what caused the images to disappear.

Didn't improve page speed at all. If anything it was slightly slower, probably due to loading more JS. Benchmarked using Google Pagespeed Insights before, tested after - no difference/slightly worse.

Hi there, thanks for your review. I'm afraid this has nothing to do with our app.. The app will have no impact on 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

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.

I started Shopify with my previous domain and have changed since. Booster apps could not detect my new domain and there is no way to change it or boost my current domain.
