Not very good for me.
I tried to go to conversion > Bytes, select a field then enter a number, the CALC put the number to a different field. I click Future Cashflow then suddenly the app stop working. The iWatch is also not very good. I need a refund on this.
Great calculator
Great calculator, great features; I just love it.
Why all the pop ups?
I want to use a calculator. I don't need a tutorial on how to use a calculator every time I open the app, without any way to close it. The functionality is fine, if you can get past the tutorial every single time.
Sometimes basic is best.
i really like this calcuator; does x-actly what i need it to, without all the bovine exhaust one usually has to put up with free apps. nice!
