With an array of different app switcher alternatives on cydia, it’s tough to find the one which is suitable for you. However, I would be prepared to bet an awful lot that you’ll find something you like within ‘Aero’. It’s pretty much the definitive app switcher, and it looks just stunning. There are an assortment of options, and around 10 different app switch animations, all of which are smooth, effective & ergonomic.
Aero will set you back $1.99 on the ModMyi Repo, for the amount of work which has clearly gone into this tweak, this is a fantastic price.
