simple and clean
This is great! Finally someone has created an RPN calculator with as good and simple UI as the Apple calculator. 99% of the time I don’t need the functions of a scientific or business calculator, but I still want RPN to be able to do simple transactions speedily. Now I have it — thank you!
Response from developer
Thank you so much! Hope you are still using it. Let me know if you have any other app ideas as I want to do a new project soon
