Freezes

Paid for the app and it freezes after using the calculator for less than a minute every time I open the app

Response from developer

Thanks for letting us know. You are unfortunately the first person reporting this problem. Can you please share the exact steps you take which freezes the calculator? We cannot observe any freeze 🥶 on our side.

Only a few equations

Not worth it

Response from developer

Thanks for your feedback. Our app actually has a wide range of statistics features. We'd be happy to answer any questions you have about the app.

Love the app.

Generally exceptional. One issue is that data entry is landscape but to clear the data you have to change to portrait and clear the buffers then click “done” twice, to return to data entry mode again, surely this could be more streamlined?

Response from developer

Thanks a lot for your feedback. Definitely the flow can be improved a bit. But we would like to make sure you are aware of the capability of entering data in the portrait mode as well. If you swipe up on the display area, a menu pops up where you can choose an option called "Show Add X/Add Y". If you need more help, please feel free to email us calc@dogahe.com. Thanks for your feedback, again.
