Does not work on iWatch 3
Just paid $1.99 for this calculator. It will not open in my iWatch 3. That’s $1.99 I’ll never see again!
Developer Response ,
This app will run on all models on Apple Watch running watchOS 2 and later. It won’t work on anything called “iWatch” unfortunately!
Best looking watch calculator
Of course I like it!
