5By Salty.anglerI have used HP calculators for many years. For me this works great and I carry it with me in my phone.#### Your search is over!

5By TaotaitoTrust me. I have downloaded most free and payed calculators out there. This is it! This is the only calculator that I can say does everything others don't. If there is a function or key you don't see you can create it yourself!! Heck, even better: I have asked the developer for help and he sent the code to copy and paste into a new key!!! Rearrange keys the way you want. And it does include the always elusive statistics mode. Go ahead, look for other calculators that offer custom keys, copy/paste keys wherever you need them, create your own layout, RPN, statistics!!! You will find none. This is the only calculator you need.#### Investor

5By Moosh2017This is a powerful and time saving app that I use daily. It has been very helpful in my job by allowing quick access to so many tools/formulas in one place. It has many unique features and capabilities that you can't find together in a single calculator.
