I’m stuck converting numbers

You can try out the “Explain” function inside Binary Challenge App. It will show you a step by step explanation for every conversion step. To go there, just start a game, try to guess the numbers and if you got it wrong, click the “Explain” notification.

I’d like to enable more options and support the developer!

You can immediately enable features like “hexadecimal” and all bit-sizes via in-app purchases. To access the in-app purchase screen:

  1. Go to the main setup screen in Binary Challenge (where you can select the numeral system, bit-size and mode)
  2. Tap the little “star” on the right of the screen (next to the bit-sizes)
  3. Select the in-app purchase of your choice
