My Currency Converter is a free, easy-to-use, and efficient currency converter for iPhone users. It supports over 150 different currencies, including BitCoin, LiteCoin, and Dogecoin, making it one of the first converters to do so. The interface of the app is incredibly simple and user-friendly, making it easy for anyone to use without any prior knowledge of currency exchange rates.

One of the best features of the app is that it updates exchange rates automatically, so you always have the most up-to-date information. Additionally, the app uses 3 decimal places for greater accuracy. You can convert currencies as you type, and there is no need for a "convert" button. Finally, the app is optimized for the latest iPhone and iPad models.

Overall, My Currency Converter is a great app for travelers or anyone who needs to convert currencies quickly and accurately. Although similar to XE currency converter and Currency Converter Plus, My Currency Converter sets itself apart with its support for BitCoin, LiteCoin, and Dogecoin. The only downside is that this version is ad-supported.
