Stride is a new iOS tweak by Adam Bell that lets you unlock your device using a custom gesture.
Never again do you need to worry about entering some lengthy password, or are limited to 9 points on a grid. With Stride, you unlock with gestures, and custom made gestures at that! Simply draw your password. That's it.
*Even though Stride is pretty secure on it's own, for best effect you should set a PIN/Passcode as it makes things extra secure, and a lot nicer too!*
You can purchase Stride from the Cydia Store for $2.99.
