Lack of support and features
Seth Calkins
We've been waiting for almost 2 years for simple date calculation to be implemented... I had high hopes
Avoid this app.

UPDATE 11-03-2016: All my formulas are gone, and I didn't reinstall anything. Puff, just gone on opening. Great work Calca, farewell forever... :( OLD REVIEW: It seems a promising app but so far I've got zero support from developers, after years I wrote them. I'm stuck with a data type conversion (how to convert 10 eur to a pure number) and i can't find anything in the very limited documentation. :\
My go-to app for calculations now.

Calca is my favorite Math program. The developer's responsiveness on Twitter is amazing. It has quickly replaced Pacific Tech's Graphing Calculator as my go-to back-of-envelope estimation tool. Soulver never lived long on my Mac or iPhone as the "running total" quickly got on my nerves as being often highly out of context, even for their example support files. I love how straight-forward Calca is in it's definition of functions and output. I love how well it handles and resolves physical units (so long as unit definitions are declared early). In a few cases when I got a spinning-beach-ball after mistakenly entering a very large calculation, I just force-quit, and when relaunched, I was only a minute change from recreating my working file again, even though I'd never manually saved the new "untitled" file. I really appreciate it using built-in OS X document features like auto-saving and iCloud. In hindsight Calca feels more valuable than the price in the Mac and iOS App Stores. If the developer ever releases a paid-upgrade, I will happily be one of his first repeat customers.
One of my favorite apps

I've been using Calca for a very long time and I just love it. It's one of those very simple to use apps that fill a very real need. To be honest, my usage on the iPhone tends to be a little less involved than on the Mac but I still use it very frequently. On the Mac, I use it so much that people at work sometimes joke about it.
Surprising

I went looking for a good RPN graphing calculator in the App Store. After trying several that I didn't really like I found a review in the web for Calca. It sounded interesting even though it wasn't what I was initially looking for. After using it for a few weeks I continue to be impressed with the visual format and features. It's my new favorite app.
Doesn't work at all
jpjerkins
On a iPhone 7 running iOS 10.2.1, I can't create a new calculation, or even a new folder. The only thing that appears to work is switching between light and dark themes. A shame, because I really liked this calc many moons ago. My hope is that this review will get the author to update the App for iOS 10, which is what I expect is needed.
Wonderful Application

This is a powerful tool. It helps me replace most of the reasons why I use spreadsheets. The recent updates are awesome. I love how it allows you to set variables. You never realize how valuable it is to use variables when doing calculations until using Calca. I really wish that the developer adds a charting feature or a way to use a value from a variable in one calculation to another. Also a charting feature and financial functions. Regardless the app is totally worth it!

I have used this app for over a year. Calca performs as represented. It is capable of very sophisticated math applications. The seamless interaction with text makes it excellent for documenting the logic of you calculations. The learning curve for this application is very short. You will find it useful quickly.
