Catch fake discounts before you buy
We unmask fake “X% off” sales by tracking a product’s real price history across Amazon, Myntra and Nykaa — so you know whether a discount is genuine, or just the everyday price wearing a costume.
No waitlist signup needed for the Android beta. Prefer a launch email?
Early access. No spam — one email when we launch.
Now in closed testing
The app is live as a closed test on Google Play. Two steps, and they only work in this order.
This closed test uses a third-party tester group, so this has to happen first. Join with the same Google account you use on your phone.
Join the tester groupOnce you’re in the group, open the opt-in link, accept the test, and install CartUnmask from Google Play like any other app.
Opt in and installUse the same Google account for both steps. If Play says “App not available”, check the Google account on both pages, your group membership and whether the test is available in your country. Then reload the opt-in page. If it still fails, contact support; the message alone does not identify the cause. Testers get the full app; we read your feedback at support@cartunmask.com.
How it works
Paste an Amazon India, Myntra or Nykaa product link. Some pages cannot be read or matched yet.
We check the price history and verified comparisons available for that product. New products may need more evidence first.
A plain-English call: real saving, fake sale, or buy cheaper elsewhere — with the number to trust.
