Moun Movies is a free, ad-free web app designed for film fans who want to organize their movie and TV series collections. It helps users replace spreadsheets with a searchable catalogue of Blu-ray, DVD, and UHD discs, with options to add titles by barcode or manually. Users can record purchase details, including price, shop, date, notes, and labels, then filter and sort their collections and view their total value.

The app connects to The Movie Database (TMDB) to provide localized movie, series, and actor information, including cast details, posters, ratings, trailers, and streaming availability where listed. Users can track watched movies and episodes, explore disc release details, and browse upcoming releases. Collection and viewing statistics offer insights by year, category, format, and other measures.

Moun Movies also supports custom public or private lists, shareable lists of discs for sale, and connections with friends. Users can compare ratings and view friends’ public lists.
