I would not recommend using their "experts" to boost your page speed. Paid good money and my store still has low score of 45 on Google page speed, 30 in Swift app, and 30 on shopify. Not happy that I didn't get what was expected.

I Do Not Recommend This App. The First Day I Downloaded This App I Used It, and it Requested to optimize and speed up my theme so I let it. It Completely Destroyed My Theme And I Had To Use A Backup That Some People May Not Have. They ended up giving me a replacement 5 days later which was slower than the original theme. The Support Isn't even online when there hours say they are. Not Worth the download and definitely not worth the price, I had there premium package going through all this.

Unfortunately, this app wasn't good at all. The minimisation process caused all duplicate theme files to have the store layout break and destroy the look of our store. While this did not go to the main site, it was pretty bad considering that we back up our site before making any changes and now we can't due to the fact that none of our duplicate theme files look anything like the original.
Hi Justin,
Here's Maria from Swift ‑ Page Speed Optimizer Support Team. Thanks for sharing your feedback to our app.
Firstly we deeply apologize for any inconvenience that may have caused to you.
As we have read your feedback, seems that you had made a duplicated theme version already before you have optimized and published our code on your theme. If this is right, there might some points made you misunderstood our app process. Please let us explain you clear our process as the following:
First, when you have done optimizing your theme, our app will allow you preview all changes on a duplicated theme (this is created from our side to make sure that you could preview and publish all codes on your live theme once all looks good and properly.
Second, if you might have missed this preview step and published our code on your theme, then all codes would be applied on your theme immediately. And this case, it might have published all codes on your duplicated theme which you have prepared by yourself before.
If there is any unexpected problem on the theme, don't worry. Since we always put the theme safety on the highest priority so there is a button "Remove all codes" included already in our app. Just click on this button and then your theme will be revert back as the origin.
So please give us one chance supporting you and get contact us via this email support@perfectapps.io or our live chat. We're willing to check and give you further assistance.
Regards,
Maria

The day I installed this app was the day my website went insane. I had multiple issues right out of the gate with this one. I ran the free speed optimizer and also used their image tool to optimize 100 images. My thinking was I would test the free version, and if it worked I would pay for monthly optimizations. Test failed.
The first, and biggest problem, was that the app made a duplicate version of my website. I did not realize right away, but the "optimized" theme was downgraded from Dawn 7.0 to a modified Dawn 4.0 that was unable to update. And not just the theme it duplicated....ALL my backups were suddenly Dawn 4.0. My website is less than a year old, Dawn 4.0 was never previously installed on my site, ever.
I also had multiple product images that simply vanished and needed to be re-uploaded. On mobile, my product image swipe quit working. Even though it would say 1/4 images....It would only show one on mobile. I also had two "sale" icons on the products that were on sale, and one was half way off the screen so it was definitely causing glitches. Random icons on my website also disappeared and my website was overall glitchy. The optimizer tool got my page speed from a 28 to a 41 right away. However, the next day I was down to a 21 page speed and my website was simply not working.
I decided to try to update my website to Dawn 9.0 since 4.0 was such an old version I figured that could be part of the problem...But no, the theme was modified and could not be updated. I had to download a fresh version of my theme. None of my page templates would transfer....I would have to completely re-design my website.
So I got in touch with Shopify support hoping for an easier solution, who told me whatever the optimizer did to my theme to remove the "unused" javascrips and css, did something to my theme files. They suggested I contact the app developer support and ask for whatever they did to my website to be rolled back or removed.
The Swift app developers got back to me quickly and looked into my issue, which I was happy about. However, they came back and told me it was "impossible" that my themes were downgraded to 4.0, and that it was "unreasonable" that I did not notice immediately (Do you check what version of theme you're using every day?) They offered zero solution, and told me to go back to Shopify with their email. So I did.
Shopify support agreed that the email from the Swift app support was incredibly unhelpful and basically dodging responsibility. I spent a whopping four hours with Shopify support, and spoke to multiple people as they sent my case up the ranks to figure out why my site wouldn't update, why there were so many glitches, and why none of my page templates would transfer to my fresh Dawn 9.0 theme download from the modified 4.0 themes. After all that time, it was finally suggested that I just rebuild my page themes and redesign my website. We had to delete all my old backups that were corrupted by the Swift Page Speed Optimizer tool and start over. Devastating.
After removing all of the theme backups that were corrupted and starting on a fresh theme download....My google page speed went from a 21 to a 64. Removing whatever the Swift app did, fixed everything. My website now runs flawlessly with a vastly improved speed score. In hindsight, I should have just upgraded to 9.0 before trying this app.
I asked the Shopify support rep how a Shopify app from the Shopify App Store could so severely damage my website files...and they told me that Shopify has no control over what apps are on the app store and to use caution. They told me the best thing I can do is to leave a detailed review of what happened so other users may not have this problem. So here I am .
I give one star for the support team responding to me, thanks for the response, as unhelpful as it was. Otherwise, I would avoid this app, or any app, that automatically alters theme files. Zero stars.

Deleted the app, and not only does their code stay, but it also took down our website, on every single theme. Sent them an email but we never got anything back. As long as this wont get fixed, I'm leaving this 1 star review.

There is even more, we have a button "Remove code" in the app, if you have any issue after publishing changes, you could click the button, all our code will be removed.
We're looking to hear from you to solve the issue as soon as possible.

I'm just telling the truth.
The free plan of this app does not give you any improvement in the loading speed of your web pages. This is what the customer service of this app told me. The moment I downloaded the app, the customer service came to me and asked if I needed to buy extra services, and I didn't even start doing anything.
Hi there,
I am Julie from Swift - Page Speed Optimizer Support Team.
Firstly, I sincerely apologize for any inconvenience caused to you when experiencing our app.
Regarding your concern, the Free plan is now providing websites with Pre-loading function. By consuming data from google analytics, we analyze this mathematical data to predict the user's behavior and dynamically create a predictive model that can be used to smartly prefetch only what the user is likely to need. That technique will help to make the page load faster to visitor.
However, for heavy websites, just that technique is not enough to enhance the speed performance considerably and boost the speed score significantly. To address speed issue on Google PageSpeed Insights, it needs a deep investigation and human efforts. Because the situation is not always the same on all websites, we have recommended you to consider our Swift Expert service where our senior Developer will help to address the problem for you in a more effective way. Also, in our pricing, we only guarantee the improvement of speed score with the Expert optimize option.
If you still have any further concern, please don't hesitate to contact us via email support@perfectapps.io. We are always willing to help.
Kind regards,
Julie
