Stacker is three apps in one: a library organizer that untangles and deduplicates your whole collection, a hi-fi player with real EQ and a live visualizer, and an export hub that sends your music straight to your phone. All local. All yours. One price.

Most people come to Stacker to clean up their library. They stay for the player and the freedom to take it anywhere. Here is everything it does, split into the three jobs it does best.
Years of downloads, rips and transfers leave most libraries a mess: misspelled artists, five copies of the same song, albums missing track 7, folders named "New folder (3)." The Sorter scans every connected drive, reads the real metadata inside each file, and rebuilds it into a catalog you can actually browse, showing you the full plan before a single file moves.
The premium players charge a yearly fee just to listen. Stacker bakes a serious player right in: browse a wall of album art, jump between albums, artists, playlists and songs, and filter your whole collection by audio quality from Lo-Fi to Ultra-Hi-Fi. Cover art, synced lyrics, an equalizer and a visualizer are all included. No bouncing out to another app to hear what you just organized.
The Exporter turns a clean library into a portable one. Drag in albums, artists or whole playlists, build a queue, and send it all at once - to an external drive, a folder, or straight to your phone over your local network. No cables. No cloud. The companion mobile app receives the music over Wi-Fi and plays it right on your device.
