Bitcoin Sentinel is an iPhone app developed by Victor de Carlo Milani that provides users with a quick visualization of the value of Bitcoin being traded in the market. The app also offers calculations based on the quantity of Bitcoins.

With Bitcoin Sentinel, users can monitor the value of various cryptocurrencies including Bitcoin (BTC), Ethereum (ETH), Stellar (XLM), Ripple (XRP), Bitcoin Cash (BCH), Litecoin (LTC), Tether (USDT), Dogecoin, Dash, Miota, Bitcoin Gold (BTG), Ethereum Classic (ETC), Cardano (ADA), Polygon (MATIC), Pancakeswap (CAKE), Solana (SOL), and Polkadot (DOT). The values can be viewed in dollars, real, euros, and British pounds.

In addition to providing real-time ticker information, Bitcoin Sentinel offers exchange charts for users to analyze the trends. The app also includes a dedicated news tab, sourcing news from various reliable sources, allowing users to stay updated with the latest happenings in the world of cryptocurrencies.

One of the key features of Bitcoin Sentinel is the ability to create rules to monitor the values of cryptocurrencies. Users can set notifications to be alerted when a certain value exceeds or falls below a specified amount in the market. However, it is important to note that due to the volatile nature of Bitcoin, users may receive multiple notifications in a short period of time.

Please note that to receive notifications, users need to be logged into the app. If you experience any issues or have feedback, you can contact the developer via email.

Developer's note:

The app is free to use but includes advertisements to support its development. Your support and understanding are appreciated.

Bitcoin Sentinel retrieves its data directly from the exchanges, ensuring accurate and up-to-date information for users.
