i am a big fan too and exactly same issue of tracking wached episodes
btw i was wondering how the app would work @ copernicious ?
i mean it would be integrated to said services or else how it ll know what i watched ?
basicaly my requirements are havin a logbook kind of app which pulls data of anime lists and i can flag and rate them also support for custom entries and social and streaming aspects are more an afterthought as they work well mostly.
thanx
