Plus, making your own one in excel (I did it some time ago) helps you understand the code better, and allows you to customise the tool to your needs. I included an external pressure calculation in it per the rules of ASME VIII-1 UG-28.
I have been using a handy one called PipeSelect. This covers a lot of materials, pipe sizes and design temperatures. You may check youtube for that. This saves me a lot of time as it is quick and easy to check.
