Crypto Coins Watcher is a free Android app developed by Sylvain Saurel, designed to provide real-time information about the values of Bitcoin and Altcoins. With more than 1000 Altcoins available, the app provides real-time data for each cryptocurrency coin, including its symbol and complete name, price in US Dollars, Euros, Bitcoin (BTC), and more than 20 other currencies, 24-hour volume, market capitalization, available, total and max supply in USD, and change in the last hour, day, and seven days.

You can choose your favorite crypto coins and place them in your favorites list for quicker access or use the quick search function by entering the symbol of your preferred Altcoin. The app also features a converter to convert the value of your favorite crypto coin in your currency. You can follow your favorite coins directly on the home screen by using the available widget.

The app offers real-time notifications that alert you of big changes for Bitcoin. You can also discover the Pro version of the app that provides an ad-free experience. If you have any feedback or ideas to improve the app, you can contact the developer via email at
