Since there were so many upgrades to CALC 1 in version 4, we had to make it a separate app.
The new version is available as a part of an App Bundle in the App Store.
Select the Bundle, then 'Complete the Bundle' for a free copy for owners of version 3.5.
Use the search to find documentation on any subject! The search field is at the top of every page of the documentation.
opens the CALC 1 help page for that calculator. An internet connection is required.
I'll be using the CALC 1 Facebook page to answer questions and discuss new features. Please Like the page!
