Good for beginners
Edited : This is a good app but I think there is a slight bug. I did the right answer but it still came out wrong. Emailed the developer and they explained to me clearly already. Fast reply too. Thank you! Also it would be good if the handling of the “enter” or “submit” or “check” button to be above from the keypads rather than down below that we have to click on the screen again just to click the submit button. Or maybe make it that we can just press enter to submit would be great too.
