Includes an Apple Watch app, so you can calculate on your wrist!
Fixed a problem installing the watchOS app on Series 4 watches paired with an iPhone 6 Plus.

Ratings and Reviews
Comprehensive scientific calculator with a nice UI
Nice design, lots of features, and a tape make it worth the price of admission. Conversions and constants likely make it more useful for scientists and math-types... The only thing I wish it had was financial calculator functions, such as TVM, mortgage tables, and percent change. The developer seems to be very open to recommendations and suggestions. I’ll likely give it 5 stars if these features get added in the future.
Great app! Love all the conversion features. My only issue is that on my iPhone 7s running iOS 12.1 the digits are scrambled when the phone is held in portrait mode. They are properly ordered when in landscape mode and they are always correct on my iPad. I can’t use the numbers “8” or “9” in portrait mode on the iPhone because they are out of place and covered by other numbers.
Tightly programmed highly configurable calculator
This calculator is one of the best calculators on the app store due to its extremely high customizability and large selection of themes to choose from. The only things the calculator can't do are financial calculations.
But there are still some features to improve the user experience. Namely, there should be a button that you can add that allows you to switch layouts with a press. Siri shortcuts is way to slow for layout switching. Also, on the display each line should have a distinct line size and the tape should have a configurable line size instead of larger tape.
