Is there an app that works like a checkbook register?

I've been looking for a way to manage my finances more efficiently, especially with all the transactions I make using cryptocurrency. So, I'm wondering, is there an app out there that functions similarly to a traditional checkbook register, but adapted for the digital age? I'm looking for something that can help me track my income, expenses, and balances in real-time, while also providing insights into my spending habits. Ideally, it would be user-friendly and secure, ensuring that my financial data is protected at all times. Do you have any recommendations for such an app?
