app slider is a new modification available in Cydia with which you can add two shortcuts to the two applications you prefer on your lock screen.
These accesses will appear on the sides of the unlock slider, making this one smaller (and truth be told: unaesthetic). It supports unlock codes, It asks for it when you press the application, I know this is important because some Cydia applications skip it.
If you like it in concept, I recommend you see Locksliderz, for me much better achieved, with smaller icons that you will not press by mistake and the possibility of putting 2 or 4 icons on your lock screen.
You can download it free on Cydia, you will find it in the BigBoss repo. You need to have done the jailbreak on your device.
