Get freedom from your phone’s obvious limitations. Use Hex,Dec,Oct,Bin(Dev Calc), made by 12KK, a Productivity app on your PC or Mac with BlueStacks, and level up your experience.

Hex, Dec, Oct, Bin (Dev Calc) is this neat calculator app a lot of devs or tech folks might find useful, but honestly anyone dealing with numbers outside regular decimals could get something out of it. It basically lets you mess with hex, decimal, octal, and binary numbers all on one screen, so there’s no switching between tabs or anything — it’s all right there. Makes those conversions way less annoying. You can plug in a value and instantly see what it looks like in each base, no manual copying or retyping. The big 19-digit decimal display is easy enough to read, so even chunky numbers won’t get lost.

What’s handy: it lets you go as high or as low as those big hexadecimal limits, so there’s a lot of range. There’s also a conversion reset you can turn on or off if you need a clean slate while working. When trying it out on PC with BlueStacks, it feels smooth and doesn’t look weird stretched on a bigger screen — the numbers and buttons are still easy to tap. For anyone who’s ever lost track flipping between bases on a regular calculator or keeps forgetting how to write a hex number, this one’s just straightforward. Nothing flashy, but everything you want is on one page without fuss.

Big screen. Bigger performance. Use BlueStacks on your PC or Mac to run your favorite apps.
