### 4/5 — Great idea!

*2023-12-13*

I am an engineer, so I grew up with the HP-15C and the Casio Fx-602p.  For many years I have used an app which was a reproduction of the Casio Fx-602p.  But, when I upgraded to an iPhone 14, the app no longer worked and I had to replace it with something quickly.  So, I went searching and found this Calc1.  It does work, the instructions are correct, but not very easy to understand.  Maybe some more, or better, explanation would help.  Eventually I got it working (Ah now I get it! 🤓), and now I like it.  I also like that you can use javascript to program functions into your calculator - for nerds like me who like to do that sort of thing.

**Developer response:** Thank you for your review! Since your review we've added a dozen tutorial videos to make CALC 1's benifits clearer and more accessible. We plan to add more tutorial videos. 
We welcome your feedback on these additions and any suggestions for future topics.

### 5/5 — Best than HP. Trust me. It’s all you need.

*2023-11-01*

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.
