About this app

■ Make the calculator you use every day your own.

You open your calculator countless times a day — so why not make it something that lifts your mood every time you see it?
Oshi Calc lets you set your favorite images on the background, the display, and every single button. Dress it up with a photo of your oshi, your pet, your family, or a favorite view, and make everyday math a little more fun.

Of course, it also works as a proper calculator with the four basic operations and a calculation history.

■ Main features

[1] Customize freely with images
Set any image on the background, the number display, and each button. Take a photo with the camera or pick one from your gallery, then crop it to frame it just right.

[2] Save and switch between themes
Save "a background + a full set of button images" as a theme, and keep several. Switch with one tap from the chips below the header, and add, rename, duplicate, or delete themes freely.

[3] Copy & paste images
Reuse an image from one button on other buttons, or "paste to all buttons" for a consistent look in seconds.

[4] Background colors
Not just images — you can set a solid background color too.

[5] A practical calculator
Four operations (+ − × ÷) with chained calculations, AC / ⌫ / ± / %. Digit grouping, rounded results, and divide-by-zero handling — everything you need for daily use.

[6] Dark / Light theme
Switch the display theme between dark and light.

[7] Keyboard input
On a PC browser, number keys and + − × ÷ / Enter / Backspace are supported.
