About this app
Made for iPhone Duo. Half open, the home splits across two screens; open wide, the cube fills the view. Start the Friday Weekly Cube on your Duo from day one.
Every Friday, the same cube goes out to everyone in the world. Solve that one scramble and compare your time on the leaderboard.
Scan your real 3x3 cube with the camera, and Cube reads its state and guides you move by move until it is solved.
For first-timers who just want to solve all six faces, and for cubers chasing a faster time.
■ Weekly Cube
One scramble per week, identical for everyone.
Your solve time is recorded on the leaderboard so you can measure yourself against other players.
Register a public nickname to join the leaderboard — it carries over to new devices and reinstalls via iCloud Keychain.
■ iPhone Duo
Works with iPhone Duo. Open it all the way for a big cube. Fold it halfway like a laptop, and Real Timer shows the clock on the top screen and the pad for your hands on the bottom.
