CALC is really clever.
CALC does live math expressions: From simplifying even the simplest like "1+ -2", that you can type the same way you'd on a paper (without the need for "negating" a number afterwards) ... to more advanced expressions like "1/3 + -( 3 x 9(log(4;8) + sind(90)))" where you can even specify a base for the log() function, use natural input without the need to insert a multiplication symbol or worry if you did the trig. function "sinus" in RAD or DEG, or closed all parentheses.
By swiping left and right on CALC, you can easily access over 60 advanced math functions, constants and symbols + create limitless number of your own!
CALC remembers what you have calculated. Swipe up, and you can see all your previous calculations and perform aggregate functions.

Ratings and Reviews
I searched and searched for a decent calculator for my Apple Watch. After deliberating the cost, I finally went for this one. It has the features I need/want, and works pretty well. I like the haptics feedback when typing. For some reason, I couldn’t add the complication to my watch face from the phone app, so I had to do it on my watch. It took me a bit of time to figure out how this app works, but I think it’ll be easy and fast to use with time/practice.
The only Calculator I’ll use
Have been using this calc for years and the only one for many reasons.
Most calculators don’t give me the option to see what I’m actually pressing. I like to see my numbers and not just the total.
Plus, I love the interface. Stunning and easy to use!
Ugh I just want to do math
I have used this calculator for a number of years. However the most recent update throws up a dialogue that I’m supposed to swipe down to close but it doesn’t close and now I can’t do any kind of math to save my life!
I received a dev response email today. I can’t tell who is being lame here. iIs it Apple because I only received the email about the developer response today, Oct. 2018? Or is it the developer because they somehow backdated their response, which is dated the day after I posted this review. I suspect it’s both! And restarting the app I didn’t help! You had a bad update own it!
Developer Response ,
Unfortunately when/how the AppStore review responses get to the end users is outside of our control. We’d like to help but without additional information that is very difficult esp. since yours is the only issue instance we know of. Please contact us via UserVoice in the app itself or via the support link on AppStore CALC app listing and include your device info and ideally a screenshot. Thank you for taking the time to help us resolve the issue to your satisfaction.
Original response: Please close and restart the app and/or use one of the support channels to submit a screen shot and your device details so we can identify the issue. Thank you for using CALC! :-)
