Pros and cons of CALC Smart app for iPhone and iPad

CALC Smart app good for

This is my favourite calculator app. It does everything including conversions.

I was looking for a calculator that can instantly display the sum, found this one and tried. Found it is useful and the support team is dedicated to keep amending this app. It is one of the best calculator now.

very nice calculator. good for daily use and scientific usage as well.

Best App of this kind of apps and best widgets, intuitive, easy e MUST HAVE !

Way better than the stock Apple calculator... By leaps and bounds!

iPhone 6 Plus user: Update: Latest version 3.5.4 works again! Version released 3.5.2 on June 9 crashes, Waiting for next update.

Some bad moments

This app did not fit on the watch face properly. Too many options and could not perform basic functions with ease

Its a calculator so it should get number right. EE should mean "x10^" or "times ten to the power of". Press it and you get the e number of 2.71... Very different. Very wrong.

Serviceable calculator on iPhone, but even when I could get it to work on the watch, it was wonky. Now it wont even load on the watch. Dont bother; there are better calcs out there.

Still this app cannot do trigonometry in DEG mode correctly. What a shame. Try asin(0.5) You do not get 30 degree. But some nonsense due to faulty programming. I already reported the bug but no reaction. Who is programming this? Please correct. Its not seriously usable this way.

Nobody cares that the App is 3in1 btw. it is enough when you see it in the description... Banners are for stupid chinese brainbombing apps... change the icon back!

It looks great but 1 circle is 360 degrees, not 400. If the converter cant get this right then every answer is suspect.
