Free focus music app with curated playlists for deep work
A hand-picked selection of genres chosen for concentration, including chill lo-fi hip-hop, jazz, classical, indie and ambient sound.
A timer in the player interface lets you run a defined block of work while the music plays continuously in the background.
Runs directly in the browser and also ships as an iPhone app, so the same focus playlists work at a desk or on the move.
The player deliberately avoids browsing, discovery feeds and social features that would pull attention away from the task.

Find the Spotify songs you thought were lost
Pick the Spotify playlists you care about and Harken keeps watching them, recording every song that appears or disappears.
A per-day log of the songs added to and removed from each tracked playlist, so you can see exactly when something changed.
If a song you heard in an auto-shuffled playlist gets removed before you save it, the history lets you identify it and add it back to your library.
An analytics view that highlights which songs appear most often across your playlists; the site currently lists it as a forthcoming feature.
