HIIT 20 Turns Your Workout Into a 20-Artist Playlist
A 20-minute interval timer that changes tracks every minute and can build a session from Spotify listening history or public mixes.
Field notes
The timer divides a session into 20 one-minute rounds and treats each track change as the cue for the next movement. Its public-mix mode avoids account setup, while the personalized mode asks for a Spotify developer Client ID and access to top artists and Liked Songs. The page documents a notable platform constraint: Spotify playback control is limited to Premium accounts, and the app’s allowlist is capped at five people. Exercise demonstrations are marked as coming soon.
