Do you have an iPhone/iPad/iOS version?
Yes! You can download it from the App Store.
Can I buy or host a copy of the calculator?
Sorry, the calculator is no longer for sale. Please do not
email me asking if you can buy it. You are always free to link
to it!
Can you recommend another calculator that I can
buy?
Sorry, I don't keep track of other calculators - Google is your
friend!
I have an important software project - can you work on
it?
Sorry, I don't have time to take on new work.
I have another question - how can I contact you?
Just send an
email.
