FretFlo vs Vaporloop

Find a better way to play it. FretFlo helps guitarists turn chord progressions into playable voicings that work together across the fretboard. Enter your progression, choose where you want to play on the neck, and FretFlo generates two carefully selected paths through the chords. Instead of looking at each chord in isolation, FretFlo considers the progression as a whole—helping you find parts with natural voice leading, comfortable movement, and voicings that fit together musically. Whether you're working out a second guitar part at rehearsal, exploring new ways to play a familiar progression, or trying to move beyond the same open chord shapes, FretFlo gets you from chords to playing quickly. GENERATE BETTER VOICINGS Enter a progression and get playable chord shapes selected to work together—not just a list of every possible fingering. EXPLORE TWO MUSICAL PATHS Compare two different approaches to the same progression and choose the one that fits your part. CHOOSE YOUR POSITION Point FretFlo toward the area of the neck where you want to play. It's a musical starting point, not a rigid boundary, so the progression can move when a better voicing calls for it. BUILT-IN GUITAR TUNER A clean, responsive chromatic tuner is always close by when you need it. KEEP YOUR IDEAS TOGETHER Recent progressions make it easy to return to what you've been working on. GO FURTHER WITH FRETFLO PRO Unlock the full chord vocabulary, including 7ths, suspended, diminished and augmented chords.

FretFlo Pro is a one-time purchase. No subscription. Made for the moment between hearing the progression and finding your part.

VAPORLOOP turns your audio into a generative instrument. Drop in a song, a voice memo, a field recording, or anything you screen-record — then set a loop and start mangling it. Built around a granular time-stretch engine, VAPORLOOP lets you slow a loop to a crawl without dropping the pitch, or shift the pitch two octaves without touching the tempo. The two are completely independent. When it finally sounds like something, hit record. VAPORLOOP captures the live performance — every knob move included — and saves it as WAV, MP3, or AIFF. THE ENGINE - Granular time-stretch — speed from 10% to 300%, pitch ±24 semitones, fully independent - Grain controls — size, density, interval rate, spray, and stereo spread - A/B loop points set by tap or dragged by hand, with pinch-to-zoom for fine editing - Reverse playback THE CHARACTER - Tape wear — jitter, mechanical noise, dirt, and dropouts - Warble — independent wow and flutter, each with rate and depth - Pitch LFO — sine, triangle, saw, square, and sample & hold - Speed LFO — sweep playback rate without touching pitch THE MIX - Four-band parametric EQ with a drag-to-shape response curve - Reverb with decay and size, up to cathedral-scale tails - Delay with tap tempo, note divisions, self-oscillating feedback, and its own time LFO WORKING - Import MP3, WAV, AIFF, M4A, FLAC, MOV, and MP4 - Share audio straight in
