Some apps are consuming hundreds of megabytes, if not gigabytes, of storage space on your iPhone or iPad, and the only way to get that back seems to be to delete the app. I’m a bit of a cheapskate, and I go for the lowest storage option when I buy an iPhone. It’s far from ideal, but Apple charges far too much for what is a few dollars worth of storage.
