For a couple of years I used seriesguide for Android on my tablet but I received a iPad as a present and now I am missing the app. So please can’t you make a iOS version?
Sorry, no plans. The continuous costs are just too high (hardware, yearly developer fee).
The trakt.tv website lists some alternatives: https://trakt.tv/apps
Can you at least make a web version for the ios users instead of an app?
