What crypto app is available in USA?

Can you recommend a reputable cryptocurrency app that's accessible in the United States? With the growing popularity of digital currencies, I'm looking for a user-friendly platform to buy, sell, and manage my crypto holdings securely. Ideally, it should support a wide range of coins, offer robust security features, and provide insightful market analysis tools. Additionally, I'm interested in an app that's accessible on both mobile and desktop devices, allowing me to stay connected to the crypto market whenever and wherever I am. Could you suggest a few options that fit these criteria?
