iPhone
Paste a link. Get instant chords. Play along with real-time diagrams synced to the music. Works with YouTube, TikTok, Instagram, and audio files.
Riff listens to any song and gives you the real chords, in real time, so you can just play.
No tabs. No guessing. No ads. Just you and your guitar.
HOW IT WORKS
Share a song from YouTube, TikTok, Instagram, or import an audio file.
Riff analyzes the chords and BPM in seconds using AI.
Play along with chord diagrams and synced lyrics that follow the music.
REAL-TIME CHORD DIAGRAMS
Chords scroll in a carousel perfectly synced to the audio. Each diagram shows finger positions on the fretboard so you always know what to play next. Swap between voicings to find fingerings that feel comfortable.
SYNCED LYRICS
Word-by-word lyrics scroll and highlight as the song plays. Chord names appear above the words where changes happen. Tap any word to jump to that moment.
PRACTICE TOOLS
Capo support — set your capo fret and Riff transposes every chord automatically.
Transpose — shift the key up or down with live key detection.
A-B loop — isolate a section and repeat it until you nail it.
Speed control — slow the song down while you learn.
Simplify chords — reduce complex jazz voicings to basic shapes.
No-barre mode — swap barre chords for open alternatives when possible.
BUILT-IN TUNER
A full chromatic tuner that detects your guitar's pitch through the microphone. A visual gauge shows how sharp or flat you are, with string indicators so you know which peg to turn.
BUILT-IN METRONOME
Adjustable from 40 to 240 BPM with tap tempo. Supports 2/4, 3/4, 4/4, and 6/8 time signatures.
YOUR LIBRARY
Every song you import is saved to your personal library with album art, BPM, and chord data. Search, sort, and favorite songs. Pick up where you left off with quick resume.
COMMUNITY CATALOG
Browse chords that other Riff users have shared. Contribute your own analyzed songs back to the community. Vote on accuracy so the best chords rise to the top.
PRACTICE SONGS INCLUDED
Riff comes with classic songs to get you started — Wonderwall, Hotel California, Wish You Were Here, Stairway to Heaven, and more.
WORKS OFFLINE
Chord analysis has an on-device fallback. Your library, tuner, and metronome work without an internet connection.
