I dont know much about smart phones. I am trying to get an app and having bad luck. The only device i have is a ipod touch 4th gen. I need a flash card app or some people call it index cards. it's the cards that help you memorize things. I searched the app store and all the ones that I saw require ios 7. The problem is, the ipod touch 4th gen only goes to ios 6. it is not possible to get ios 7 for this device. I also looked into using cydia, but when I searched cydia, I could not find any index card apps. assuming that i dont want to buy a new device, what else can be done? am I missing anything?
