Fluctuate

Fluctuate is a price tracker that allows you to track the price of products from online shopping websites, and unlike most of the other price trackers on the Play Store, Fluctuate is a universal price tracker, which means that you can use it to track any product from any site.

This includes many of the most popular sites like Amazon, eBay, ASOS, Flipkart, Myntra and lots more. You could use Fluctuate as a flight price tracker that alerts you when some plane tickets become cheaper, or as an Amazon price tracker that notifies you when something you're interested in suddenly goes on sale. The possibilities are endless!
