What Watcharr is built for

[2] Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. [2]

It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. [2] The page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer. [2]

Pricing and fees

[1] That page names extras for donors, such as creating lists by IMDb or TMDB ids, unlimited items in a list, and list updates every 3 hours instead of 24.
