PWA checker
Find out if your site installs like an app, sends push notifications (on iPhone too), works offline and is ready for Google Play and the App Store. Each problem comes with a plain-language fix.
Checking …
Reading the page, manifest, icons and service worker. This takes up to 20 seconds.
Five areas, about 20 checks
The same checks we run before every Setup and Launch project.
Install as an app
HTTPS, a valid web app manifest, a name, full-screen display, icons that load at the right size, and a start page.
iPhone Home Screen
An apple-touch-icon, a Home Screen name short enough not to be cut off, and launch screens.
Push notifications
A service worker, push code or a push provider, and the setup iPhone needs before it delivers web push.
Works offline
Whether the service worker handles requests, so visitors see your app instead of a browser error.
App store readiness
A 512×512 icon and a maskable icon for Android, screenshots, and what Apple's review will want to see.
Lighthouse no longer checks PWAs
Lighthouse removed its PWA category in version 12, in 2024. Chrome DevTools still shows a few installability errors in the Application panel, but there's no longer one report that tells you whether your site works as an app.
This checker fills that gap, and covers what Lighthouse never did: how your app looks on an iPhone Home Screen, whether push reaches iPhone users, and what Google Play and Apple's App Review need.
Questions
Is this an alternative to the Lighthouse PWA audit?
Yes. Lighthouse dropped its PWA category in version 12, in 2024, so it no longer gives a single installability report. This checker covers installability and adds what Lighthouse never checked: iPhone Home Screen details, push on iPhone and app store readiness.
Why does my site fail on iPhone when it works on Android?
iPhone reads different signals. It uses an apple-touch-icon for the Home Screen, and it only delivers web push to sites added to the Home Screen whose manifest sets display to standalone or fullscreen.
Can I put my PWA on the App Store and Google Play?
Yes. Google Play accepts web apps packaged as a Trusted Web Activity. Apple needs more than a website in a frame (App Store Guideline 4.2), so the iOS app should add native features such as push notifications and an offline screen. Our Launch service does both.
Do you store the address I check?
No. We don't save the addresses you check. Results are cached for 10 minutes so a shared link loads quickly, then they're gone.
Why does the result say it couldn't check my site?
Some sites use bot protection that blocks automated checks, and very large pages can time out. Ask us for a manual check on real devices; it's free.
