fitcheck
INSTALL

Pick your browser

The same fitting room, in whichever browser you shop.

The extension installs once and wakes up on every clothing page you open. Your photo stays on your device until you confirm a fit check.

Invite-only, for now

Installing is open to everyone, but signing in currently takes an invite. Request one and we'll write to you when your spot opens.

Beta builds load through Developer mode and do not auto-update — check back here for new versions. The Chrome Web Store listing replaces this the moment it is live.

Safari

TESTFLIGHT

The Safari extension ships inside a small companion app. Install it, open the app once, then enable fitcheck under Safari's Extensions settings.

TestFlight beta rolling out now

iPhone, iPad and Mac, from the same build.

Firefox

ANDROID

The only way to run a try-on extension on Android. Chrome for Android has no extension support at all, so if you shop on your phone, Firefox is the way in — install it, add fitcheck, and your usual stores work as they do on desktop.

Coming to Firefox for Android

Works on Firefox for Android and desktop Firefox. Requires Firefox 142 or later.

AFTER INSTALLING

  1. Step 1

    Open any product page

    Go to the store you actually shop at and open a clothing product page.

  2. Step 2

    Click the fitcheck button

    The panel opens on the page. Link your fitcheck account — approval opens in a separate fitcheck tab so you can verify it.

  3. Step 3

    Add one photo

    One clear, full-body photo. It stays on your device until you confirm a fit check.

  4. Step 4

    Fit-check the page

    The store's own product photography comes back re-shot on you — same page, same prices, real checkout.

Your photo stays on your device until you confirm a fit check. Generated results live in your fitcheck account.
