Two clear data sources
Spotify Account Data supplies Liked Songs; Extended Streaming History supplies lifetime listening statistics.
OFFLINE MUSIC ANALYSIS FOR IPHONE & IPAD
For Spotify, your currently Liked Songs define the selection while Extended Streaming History adds plays and skips. Both are joined locally, with no account, ads, or cloud upload.
App Store download after approval

APPLE MUSIC · IOS BETA
The iOS TestFlight beta shows only favorited songs that are also in your Apple Music library. Swiping left revokes a favorite only after individual confirmation; undo restores that exact song.
YOUR HISTORY, YOUR DEVICE
YourLibrary.json determines which Spotify songs are currently saved. Full listening history is only the statistics source. Without the library, analysis of all played tracks is labeled explicitly.
Spotify Account Data supplies Liked Songs; Extended Streaming History supplies lifetime listening statistics.
Only matching plays, longer plays, listening time, skips, and last played dates are assigned locally to Liked Songs.
Swipe right to keep, left to select, or down for later – with undo included.
Rarely played, often skipped, or dormant: choose the perspective that helps you.
Share your local selection as a UTF-8 CSV with correctly escaped fields.
Try the full flow instantly with fictional tracks, original artwork, and clearly marked demo values.
REAL APP SCREENS




PRIVATE BY DESIGN
Offline import and the web app remain fully local without a provider login. The separate Apple Music area in the iOS beta communicates directly through MusicKit only after system permission and stores swipe progress locally. SkipLess contains no ads or tracking.
SERVICE REQUESTS
The app already works fully offline. You can optionally join the list for exactly one service.
