Stog vs Sortwave

Your music, on an endless mix that fits the moment. Stog is a DJ for the music you already own. Pick a mood — Focus, Energy, Sleep, Driving and more — and Stog builds a continuous set from your own library, refilling as you listen so the music never stops and never drifts off-theme. Every track is analyzed on your device — tempo, energy, brightness, rhythm and instrumentation — so Stog understands how your songs actually sound, not just their genre tag. Your music and its analysis stay on your device. No account. No ads. MOOD THEMES Chill · Focus · Happy · Melancholy · Romantic · Energy · Sleep · Driving · Acoustic · Children · Holiday · Classical — plus your own custom blend. IT LEARNS YOUR TASTE Like a song for a mood and Stog leans into it. Remove one and it stops showing up. Your picks shape what plays next, per theme. BUILD YOUR OWN MOOD Mix existing themes into a custom blend — a little Focus, a little Chill, exactly how you like it. SETS WITH A SHAPE An Energy set warms up, peaks, then eases off. A Sleep set winds down toward quiet. Stog shapes the arc of the set, not just the tracklist. MORE • Exclude artists you never want to hear • Apple Watch app — control your set from your wrist • Background playback PRIVATE BY DESIGN Your music, library, and listening never leave your device. All analysis runs on-device, with no account, no ads, and no cross-app tracking. To help fix bugs, Stog sends anonymous crash diagnostics — never your music or personal information. Note: Stog plays the music already in your library. It is not a streaming service and does not include a song catalog.
