Apps Bleeding Speed
Every Shopify app you install slows you down.
Most Shopify stores run 7 to 13 apps. Each one adds scripts. Together they push load times past 3 seconds, the point where 53% of mobile shoppers leave (Google).
New: Founder Series Watch
Even fast Shopify stores quietly lose six figures a year.
Whoosh is the Shopify speed app that wins it back with faster pages, loading key apps first and preloading the next page.

The Cost of Slow Where Revenue Leaks
Four ways your fast store is still leaking revenue.
Apps Bleeding Speed
Every Shopify app you install slows you down.
Most stores run 7 to 13 apps. Each one adds scripts, pushing load times past 3 seconds, the point where 53% of mobile shoppers leave (Google).
Lost Search Rankings
Slow stores rank lower on Google.
Google ranks faster sites higher. If your Core Web Vitals (LCP, INP, CLS) are poor, you slip down the results, and your competitors take the click.
First-Tap Bounces
Shoppers judge your store in milliseconds.
If your store doesn't feel instant on the first tap, they leave. A 100ms delay alone cuts conversions by 7% (Akamai).
Theme Bloat
Old themes quietly drag performance down.
Years of code, agency quick fixes, and unused features stack up. Even beautiful stores can be silently slow.
Smart App Loading
Apps that load smart, not slow.

Shopify bounce rate page speed: why shoppers leave after one page
A shopper taps your ad, the chestnut boots page opens, and they leave before a second page. That is a bounce. Here is how Shopify counts it, when a slow page is the reason, and the check on your phone that tells you which.

Why is Shopify mobile page speed slower than your laptop?
Your camel suede loafers load fine on the laptop in the back office, and a shopper in a waiting room waits for them on their phone. The phone gets the same page with less to work with. Here is how to tell whether it has a problem of its own, and what to check first.
Apps & scripts 7 min read
Does page speed affect SEO on Shopify?
A shopper types leather slippers into Google on their phone. Google shows the page that matches those words best, even when it is slow, and speed only counts between pages that match equally well. Here is the phone check that tells you which one to fix first.
FAQs Supportive
We’ve got you covered.
Will Whoosh conflict with my theme or existing apps?
Whoosh is built for compatibility with Shopify stores and runs alongside your theme rather than editing it. If a highly customized theme or a specific app does conflict, our support team works with you to resolve it quickly.
Does Whoosh touch checkout?
No. Whoosh can preload your cart so it opens instantly, but it never preloads checkout or account pages.
How quickly can I see results after installing Whoosh?
It depends on the Whoosh plan you’ve chosen. Smart App Loading can impact key performance metrics such as LCP and INP immediately (note: PageSpeed Insights reflects the last 28 days of data, so don’t expect immediate changes there). AI Page Preloading relies on real user data to build an understanding of common navigation patterns, so timing for results significantly depends on the traffic your website gets. Typically, we see the effects within the first two weeks.
What happens if I uninstall Whoosh?
Uninstall from the Whoosh dashboard and we remove our script, so your store goes back to exactly how it was. If you uninstall from Shopify’s app settings instead, we switch the script off remotely so it does nothing. Removing it from the Whoosh dashboard is the cleaner option because it leaves nothing behind.
How much does Whoosh cost?
Smart App Loading and AI Page Preloading are US$99 a month each, and Whoosh Max, which includes both, is US$149 a month. Every plan starts with a 7-day free trial and is billed through Shopify.
How am I billed?
Through your Shopify bill. Every plan starts with a 7-day free trial, then Smart App Loading and AI Page Preloading are US$99 a month each and Whoosh Max is US$149 a month. Cancel anytime in Shopify.
Do I need a developer to install or maintain Whoosh?
No. You install Whoosh from the Shopify App Store and manage everything inside your Shopify admin. There's no code, no theme editing, and no developer required.
How does Whoosh actually speed up my Shopify store?
Whoosh optimizes your Shopify store's page load times through Smart App Loading and AI Page Preloading. Smart App Loading manages how third-party apps load to prevent slowdowns. AI Page Preloading predicts the next page a shopper is likely to visit and loads it in the background, so browsing feels instant.
How is Whoosh different from Hyperspeed or Booster?
Hyperspeed and Thunder change how your theme loads its design, which Whoosh does not do. Booster loads a page when the mouse rests on a link. Whoosh puts your other apps behind the product photo, preloads the page a shopper is likely to open next, and measures the result in sales on your own store.
Who makes Whoosh?
Whoosh is made by a team in Sydney, Australia. It was founded in 2023, is operated by Fastlane Technology Pty Ltd, and has been on the Shopify App Store since 11 August 2025.
