Both Android and iphones require an account to download apps I believe. Am I mistaken here? Other than that they can be used in the same way without accounts. In fact, with Android an email account suffices and giving your phone number is "opt-in". Apple forces you to give your phone number to create an account last time I checked. Also no F-droid on iphones? But the iphone is the better "phone" experience because there is less bloat and UI nagging.
