Maker here. This is a Google Chrome extension which can be used to track details like Net Asset Value (NAV), % change etc of all the Indian mutual funds traded on NSE. So, you don't have to bookmark the mutual funds in your financial portfolio anymore. You can simply search for the funds and start tracking them through few clicks.
The funds that you add will be stored in your Google account and can be accessed from different machines where you're logged in in your Chrome browser.
Now I'm working on Android and IOS apps for this same use case using React Native which is an awesome framework!
