Binary Key app for iPhone and iPad

The goal of Binary Key is to pick the lock with your binary key.

You can change the digits on the key by tapping them. When you tap "pick", you will see random digits above the key. The number to the left indicates the number of these digits which are correct.

To determine whether you can open the lock, tap "unlock". If you can open the lock, you will see the key rotate in the lock.

Every time you tap "pick" or "unlock", it is possible that you will get caught.

Binary Key was designed to be starkly simple, mysterious - much like picking an actual lock. If that minimalist experience appeals to you, youve come to the right place.

If youre looking for a richer experience, try the fun Diamond and Ruby app.
