Your finger turns the dial
Put your finger on the dial and turn it, from any angle. It keeps spinning after a flick, clicks on every number, and on iPhone you feel each click.
A combination padlock for iPhone
Turn the dial.
See inside.
Mechalock brings a school combination padlock to life in 3D. Your finger turns the dial itself: feel every click and watch three hidden discs line up to release the shackle.

A real mechanism, not an animation
Look inside with X-Ray
The housing disappears and the mechanism shows through: the cam and two wheels pick each other up, and their gates line up under the lever.
Learn the sequence
Instructions show the next move and count your turns. Slip up, and they tell you to start over. Tap Open to watch the whole sequence.
Your own combination
Choose your own code on native number wheels or roll a random one. It stays on your iPhone.
It opens only when it really should
The lock opens only when the lever's fence can drop into all three gates, just as in a real padlock. Stop one number short and the fence rests on a rim. Switch on X-Ray and you can see it.
