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
The app has been very helpful. Marc helped me a lot. I must recommend this app to all of you. I wish Marc will be present when I need him.
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!
Finally an app that works! We have a large site, onshorecellars.com, with thousands of products, collections etc. This App is the only one that has worked in 4 years of searching. I have paid thousands for developers to speed up our site with nominal increases in lighthouse scores. We averaged - 35-42. 5 mins altering setting this up we are between 91-93. THANK YOU THANK YOU THANK YOU!!!!
The Flash PageSpeed Optimization app is a game-changer for my Shopify store to optimizing external URLs! The app is user-friendly and easy to navigate.
I was also impressed by the excellent customer support provided by Marc. He was patient, knowledgeable, and went above and beyond to address all my concerns. Thanks to the app and the support, my website is now faster than ever before, providing a better user experience for my customers. I highly recommend this app to anyone looking to improve their website's performance.
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.
From what i can see, I think it's made a positive difference.
An improvement to the App would be to more visibly show the before and after in terms of speed text.
Thanks for your valuable feedback!
We are currently working on such a functionality and the app will get some improvements soon
BAIT & SWITCH - There is NO FREE TRIAL!! Do NOT download this app!! They offer a "FREE" trial but in fine print there's up to $40 in usage fees. Zero clue what that was. I immediately removed app. Unsure how this ever got approved.
UPDATE: Yes you didn't charge my account because I caught your little scam of $40 usage fees for a free trial and as clearly stated above - deleted the app. Thanks for the sexist mansplaining tho.
UPDATE 2: This guy stalked me on Instagram and started DMing me. I had to block him. THEN he removed his old reply and came here and starts again. This is BEYOND unprofessional and downright creepy. It's VERY alarming you've become so unhinged over a negative review about FACTS. And yes I did use the app. I downloaded it - saw the usage fee of up to $40 when there was ZERO visible explanation and so I deleted it. The ONLY thing your non stop replies and stalking me on another platform does is prove my point - DO NOT DOWNLOAD this app!
Dear Karen,
first of all, we didn't charge your store any single dollar. Thus, I don't understand why you didn't ask our support team through E-mail or Slack about the usage fees, before leaving a bad review.
There is a 7 day trial but you uninstalled our app after 5 minutes - thus your review doesn't seem to be based on experience. Please get back to us and I am happy to explain everything in detail
Update: sorry, I just tried to help. A 1 star review for not using our app after all, without contacting us to explain it just doesn't seem fair.
The 7 day trial is completely free up and there are no charges in that period except if you pass 10.000 requests. Then a $4 charge applies up to a maximum of $40 - which equals 100.000 requests
Saw this on Youtube and it helped me to increase my pagespeed score
It works as described in the video. Simply setup and easy to use.
Good app. can highly recommend it.
Flash speed is great. Their support helped me out quickly to solve some issues I had in the beginning.
Works as expected. Thank you
One of the best apps to optimise speed. Easy to use and you get results directly
Can’t say anything negative about it. Marc & Matiss helped me to fix a few bugs I had in the beginning, since then it works great
Good app that also includes image optimisations. 100 are free each month, but the price per image is cheap.
Works well and cost effective
At first I had problems using the app but the live chat was really helpful and helped me to improve my store.
The results are promising. I will keep the app installed for another few weeks and then review again.
I have tested several other speed apps and this one gave the best results on pagespeed. Thank you.
Does what it says, also the price is really fair. I can’t complain.
My speed score went from 45 to 90+. Especially the image optimization is helpful.
It works. Improved speed from 32 to 75+!
Amazing speed app. Finally an app that work
One app that covers speed and image optimization for a reasonable price. No additional fees.
The image optimization helped me to finally pass the core web vitals. Thanks a lot for the support....
Thanks for the support. At first I struggled getting a good pagedspeed score, but Marc helped me to set everything up
Marc was a great help and definitely goes above and beyond to make sure everything is working properly. Very happy with his support.

Thank you for your review. Please contact our support or contact Marc in our Slack channel and we will figure out problems
WOW! I have been struggling for so long with my site speed and Flash just fixed it in a matter of minutes with almost no effort on my part. I honestly cannot believe how great this works. I was paying for another service and constantly had my speeds dropping into the 30's. Since installing Flash my site speed has been between 90-100 for both mobile and desktop. I cannot suggest this app enough.
Had a bit of a bump were was causing site to actually load slower, however was a temp technical issue their side. other than it works great 99% of time.
Dear Customers,
We're not aware of such issues and our Helpdesk is always available through E-Mail and Slack. Please contact us in order to solve this for you
Page speed is 99, amazing! Great app, give it a shot!
OMG!... A FREAKING APP THAT WORKS as it is supposed to! .. So if you are a small business owner with the technical knowledge of a rock but you know a mess load about SEO, Ranking and Spending a Crap ton of money on Ads that are not coverting then you know if your site speed is slow as rock, then your just burning cash.. You need a site that converts.. (or at least thats what they say) So, Iv hired shopify specialists several times over the years and paid out the nose for Website Optimizations. Well, NOT ANYMORE.. Thanks to this APP. Literally, within 2 hours of installing this app my GOOGLE scores are in the 90% Range for all 4 Scoring Matrix's. This APP is wonderful. I highly Recommended -- here are my speed site score link if youd like to see performances https://pagespeed.web.dev/analysis/https-mattressxperts-biz/kmk6rwjulq?form_factor=desktop .. Get it! it works
The huge problem with my store speed and third party app code was quite disturbing knowledge for me
Which this app and specially Marc the owner of this app did for me۔
Thank you so much Marc . very satisfied thanks again
Recommended to all good work
Excellent app for managing js, removing from specific pages etc. Pagespeed has improved significantly.
In 24 hours, Marc has helped me improve the performance of my store getting from 70% to 92% on Google Lighthouse because of image issues a lot of shopify stores are facing. He also answered the questions that I had about the app and the customer service was fluid through Slack. For this efficient customer service, I recommend using the app. Thank you Marc.
We had some 3rd party apps that loaded unused javascript, Flash allowed us to remove it from the pages where it wasn't required. Thanks
WARNING! This app adds some scripts to the template and looks real but, in reality nothing changes. It charged me while doing nothing and the support never replied to my question for help. I suspect those 2 initial reviews which tricked me to trust the app are from the developer.
Please note, that the app only helps if you have 3rd party apps installed and they load javascript. It does not help to block Javascript's of the theme itself.
