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.

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

Hello Adimir,
This is Maria from Swift App reaching out regarding your feedback for us that the app lower your grade on GTMetrix tool.
Firstly, I would like to thank you for your feedback and apology for any inconvenience may have caused to you. This problem has never happened before since we have tested on hundreds of stores and no one met that situation.
Therefore, if possible, can you please consider to re-install the app so that we can have one more chance to investigate this problem further for you?
I will have our speed expertise support your case with the highest priority.
Therefore, I sincerely hope you can give us one more opportunity to support you better.

the app was unable to optimize my theme - got the error message "theme title was too long" and then after using their other feature to try to improve speed my store went from 61 to 50 on the speed test, and a couple of hours later my theme broke. This happened on the 25 of Dec. a crazy day to optimize right. had to contact Shopify support for help because the app doesn't have 24/7 support and so they were unavailable. I subscribed to their paid plan.
Hi there,
I am Maria from Swift ‑ Page Speed Optimizer Support Team. Firstly, I sincerely apologize for any inconvenience caused to you. Due to the difference in time zone, we may not be able to support you timely at the moment. We are truly sorry for that and we are trying our best to improve our support quality in order to assist our customers as soon as possible.
Regarding the problem with "theme name too long", that is due to Shopify's requirement, the theme name should not be longer than 50 characters. When running the optimization, the app needs to duplicate your current theme and it will add more characters to your theme name, for example: "Copy of [Theme]". In case your theme name is too long, we are not able to duplicate and optimize on it and we would have to shorten the name to make it work.
Relating to the score, we have met some cases before telling us that the score decreases after installing our app. However, it may not because of our code since when you run the speed test like on Google PageSpeed Insights, there's no code from our app detected slowing down your page. In that case, we will have our senior developer investigate on each case and provide the suitable advise.
Therefore, I have contacted you via Email and Whatsapp to assist you further on this issue. Please kindly help to check our message and we hope you could give us one more chance to assist you better.
Looking forward to hearing from you soon.
Best Regards,
