High-Low Scanner is a free Android application developed by Sankaranarayanan Yelai Govindan under the Business & Productivity category. It offers a profitable, simple, and successful strategy for intraday equity stock screening. The program aims to identify areas of support and resistance, but it works best when combined with other types of technical analysis. It provides trade calculators for identifying support and resistance, including Gann Square of 9 and Pivot Points, which are widely used and popular.

The app features Nifty 50, Bank Nifty, Nifty IT, Nifty Pharma, Nifty Auto, and Nifty FO. It also includes an O=H=L screener feature. However, it is important to note that the app is for educational and learning purposes only. It does not provide any buy/sell recommendations on the stock and option. It is recommended to seek assistance from a financial advisor before making any buy/sell decision.

The app requires a good internet connection to function properly. The developer kindly requests feedback and ratings from its users. However, the app does not ask for any personal information or contact details.
