what the chrome extension does

the whole moo,
in your browser.

⏱️
toolbar countdown

The extension icon shows a live countdown to your next movement break. "45m" ticking down, then a ! when it's time.

🔔
browser notifications

Movement reminders come through the browser, once an hour from 9am to 6pm on free, with i moved! and snooze 15m right on the notification. They arrive whether Chrome is in the foreground or background, as long as Chrome is running.

📋
the chalkboard

Every reminder you leave alone puts a line on Dracu-Moo's chalkboard. Miss a few and the storm builds, then Dracu-Moo takes the popup and the notifications turn professionally sinister.

🏆
your day, counted

Tap moo once you've moved. The popup counts today, your total and a day streak, and moo levels climb from calf to legend, with a crown at 100. No phone needed.

🎶
the dance song

Hit a milestone and Moo celebrates with the dance-moo song, and at 500 you get the full anthem. You don't need to know the words. Moo does.

💰
one payment. once. forever.

Premium unlocks custom intervals (30, 45, 60, 90, or 120 minutes), your own work hours, and your pick of moo sounds (deep, gentle or dance). One payment. No subscription. Dracu-Moo is devastated.

questions about the chrome extension

stuff people ask.

No, and you can check rather than take our word for it. The extension asks for three permissions, alarms, notifications and storage, plus one outside address, RevenueCat's API, to verify a purchase. There is no tabs permission, no activeTab, and no content scripts, so it cannot read the pages you have open, their addresses, or anything you type. Since version 1.2 the fonts ship with the extension instead of loading from Google, so once installed it contacts nothing except RevenueCat. It does send RevenueCat one random identifier that it generates and stores on your own machine, so a purchase you already made keeps unlocking premium. If you buy premium, RevenueCat's checkout page asks for your email address for the receipt. Its Chrome Web Store listing declares zero data collected in all nine categories.
Yes. The Chrome extension works on any device that runs Chrome: Windows, Mac, Chromebook, and Linux. It's independent of the iOS and Android apps. If you're primarily a desk computer user without an iPhone, the Chrome extension is the best way to get SuperMoo.
Same characters, same science, same design philosophy. The Chrome extension is a separate product built for browser-based work. It has a toolbar icon with countdown, browser notifications, a day streak and moo levels, the villain escalation system, and the dance song on milestones. Premium is a single one-time payment for the extension, separate from the iOS/Android premium. The price is shown at checkout, before you pay anything.
Each reminder you leave alone for twenty minutes during your work hours puts a line on Dracu-Moo's chalkboard. Two misses in a day and the storm starts building in the popup. Three and Dracu-Moo emerges and the notifications start turning sinister, with lines like "the plan thickens. tap moo to thin it." Five and Dracu-Moo takes the whole popup, cape and all. Tap moo once you've moved and the chalkboard clears and the scene goes back to Moo.
Yes. Free is one reminder an hour from 9am to 6pm, the toolbar countdown, the chalkboard and the whole Dracu-Moo escalation, a day streak, moo levels, and the classic moo sound on tap. No account required. Premium (a single one-time payment) adds custom intervals (30, 45, 60, 90, or 120 minutes), your own work hours, and your pick of moo sounds. The extension is made by Reweave, a 501(c)(3) nonprofit. No ads on either tier.
Yes, and many people do. The Chrome extension covers you while you're at a desk in a browser. The iPhone app covers you everywhere else, including Apple Watch with premium on iPhone. They're separate purchases but the characters and science are the same across both.
