Best than HP. Trust me. It’s all you need.
Wow! Those videos are worth taking a look at. I really think your calculator is the most “usable” one. I say that from a professional perspective. It has the functionality that all other calculators miss including the HPs. I love the Focused Calculators. It’s a great way to have multiple calculators available with a flip of the finger. I wish there was a way for me to tell you how many calculators (free or paid) I have tried. And then I saw this beauty back in the App Store. Long live CALC 1!! I bought the Java one of course. And just to demonstrate that I’m not saying this because I’m a fan boy one of the things I appreciate the most about the calculator it’s its simplicity and how well it manages the RPN stack. It reminds me of the best calculator ever created HP32 s II. And if you have used that one you know what I’m saying.
