"Cute Calculator" is a simple, colorful and comfortable calculator. All two input values and result are displayed, and the calculation contents can be understood at a glance, so the child's understanding of calculation will progress. Even in daily calculations, you can check the input values even after calculation, so you can reduce calculation mistakes. Designed to be simple with limited functionality. Thousand separator commas are omitted. The screen has a design and colors that even children can enjoy without hesitation. The function to enter random integers is adapted. A child in my family who still doesn't know how to add correctly was fiddling with a real calculator that wasn't an app. Since the display is only one line, the child cannot see what the child typed when the result is displayed. Therefore, I let the child use an existing calculator app (iCalcSmart) that displays two input values and the result after calculation. Then the child might have noticed something, he stared at 1+1=2 and repeated the calculation. This “Cute Calculator" is based on an existing calculator app, but is a calculator with fewer functions and a modified design so that users don't get bored. (Useful function) - There is an [RND] key to enter a random integer number. Please use it for fair random selection, lottery, etc. - Enabled to set the range of random numbers (from -10000 to 10000) from “ⓘ” button. - When you swipe the input value field, the last entered number disappears. - You can tap the result field instead of tapping the [=] key. Or you can tap the “=" mark on the left of the result field. The developer assumes no responsibility for any loss or claims by third parties which may arise from the use of this app.
