I really like how I can choose to control ads. Some of the calculating functions are not smoothly completed is why I held back on providing a 5. I like the look and menu options like sound, appearance, and history.

Suppose i have done 20 calculations & i press auto replay button then it will show me all 20 calculations but if i press C button in between to stop auto replay it doesn't stop. It auto stops only in the end. So request you to please resolve this issue. Thank you.

Thank you for your feedback. The idea is to replicate the functionality of citizen calculator models like ct 500, ct 512, ct 555. Adding gst rates will cause the app to deviate from it.
