I've heard of an app called Spotilife and some endeavour to port xmanager to iOS but Apple's anti-sideloading stance makes it so you have to re-sign the app weekly (a process I have very little concept of since I'm on Android) and is a faff on a nin-jailbroken device.
I hate to be that guy but Mikufan is kinda right, the easiest solution is to swap to Android. Apple's design philosophy is a walled garden and making customers pay extra. "You want x? No problem, that'll only cost you $y"
