which ipad can i buy to get it to work

Hello zwifters I’m looking for an iPad 2nd gen to use. I have 2 iPad mini’s 1st gen and cant get the app to download onto them. My question is if i got a iPad 2nd gen will that allow me to get the app to download. So basically is anyone out there using a iPad 2nd gen to run there stuff.
