For anyone with a 3th party checkout app ( I have a Cash on Delivery App to reveice orders) dont install this app. I had the issue that customers couldnt checkout because the checkout app was getting blocked. After a night figuring out why customers could check out. I uninstalled the app and removed the code in my theme. For the few days the app was installed ( not used ) i payed 20 dollars.

I am writing a review because it is the only methode to reach you. I cant use customersupport , i have to install the app again

We are using a customized Empire theme. It is not obvious that one can improve speed easily n our case. However, I was amazed at how we have gained the speed. The first step was from 40-50 to 85 in Lighthouse metrics. Finally, with the help of Marc, we managed to get that last metric (LCP) to green and the overall Lighthouse score to 100/100.

This app is AMAZING!! My website speed is so much better now according to Google PageSpeed Insights. Even on mobile it loads very fast (I used to be in the red zone all of the time, even with the use of other page speed booster apps). Now I only use this app and I'm very happy with the results. Thank you for doing such an amazing job!

UPDATE:
They replied and advised me to uninstall the application.

After about 15/20 days they contacted me to tell me that the problem was solved and actually now it works very well.

Thank you

The application is great, but the support service is terrible.

I have a small problem with the app, the dashboard no longer works for me.
I wrote him 3 emails and 2 messages through Shopify, a week later still no one has replied to me.

Genau das was ich gesucht habe, es waren nur ein paar Klicks nötig und keine Programmierkenntnisse. Mein Pagespeed hat sich teilweise um 50 Punkte nach oben korrigiert!

The app stopped working 3 weeks ago, blank screen. Cleared cookies, cache and even changed browser and still does not work. Tried in a different store and and it works just fine. So the issue is only in our store... Being reaching Clauma support via e-mail and via Shopify form and no answer for 3 weeks already, the app used to work fine but the issue and the lack support will make me delete it. Would not recommend right now.

UPDATE: After some months it seems that support has reappeared and the app has being updated. It now works as expected.
