About

Music Diary

Features
Read full description

Every song you love deserves more than a heart button. PlaylistNote is a music diary where you write your listening life down by hand โ€” the playlists you dream up, the track a friend played you in the car, the album that carried you through March โ€” and keep it forever, in your own words. Streaming apps track what you played. PlaylistNote keeps what it meant. There is no login, no linked account, no internet connection at all โ€” just a beautiful notebook built for music, in four tabs: your library, your listen-later queue, your journal, and your stats. WHAT YOU GET โ€ข Playlists built by hand โ€” name one "Rainy Sunday cooking", give it a vibe and a cover, and fill it song by song โ€ข Every song carries your words: artist, album, genre, a 1โ€“5 star rating, an energy level, and the note only you understand โ€ข A Listen Later queue that remembers where each tip came from โ€” friend rec, radio, a live show, a viral clip โ€” so "what was that song?" never happens again โ€ข A listening journal with moods and star ratings: open it in a year and reread exactly how that track felt the first time โ€ข Stats that map your taste: top genres, most-added artists, playlists by vibe, and how generous your ratings really are โ€ข One-tap export of any playlist, your whole library, or your journal as clean text or CSV โ€” your data walks out with you anytime PERFECT FOR โ€ข Concert-goers who want tonight's setlist and the feeling of the encore written down before it fades โ€ข Vinyl and CD listeners logging real listening sessions, not streaming plays โ€ข Anyone whose notes app is a graveyard of half-remembered song titles โ€ข Music lovers who journal โ€” and want their diary to have a tracklist WHY NOT JUST A STREAMING APP OR A NOTES APP? A year-end stats reel tells you a number. A notes app loses songs in the scroll. PlaylistNote is built for the shape of music memory: songs belong to playlists, moods attach to dates, sources attach to discoveries โ€” and it all adds up to charts of who you are as a listener. No streaming account required, ever. PRIVATE BY DEFAULT Everything you write stays on your iPhone. No account, no cloud, no tracking, no network access of any kind. Your music diary is yours alone โ€” and the export button proves it. FULL ACCESS PlaylistNote Pro unlocks the whole studio: unlimited playlists, an unlimited Listen Later queue, an unlimited listening journal, every stats chart, and text + CSV export. Choose the weekly plan, the yearly plan, or pay once with lifetime โ€” subscriptions auto-renew until cancelled. Start tonight: log the last song that gave you chills.
