Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
51/100
faster than 51% of Music apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Harmonaut: Chord Player
Harmonaut™ is a chord instrument you play by feel. Press a key and hear a rich chord, voice-led smoothly from the last one, no theory needed. Build a progression, shape its mood, and export it as MIDI for your track.
Two faders let you shape the mood as you play: more tension or less, brighter or darker, even major to minor. Chase a moody electronic progression, a warm lo-fi loop, a jazzy turn, a cinematic swell, or a simple pop hook. It all comes from your intent, not from naming chords.
HOW IT PLAYS
• Tension that actually resolves: chords that lean, pull home, and land, so your progression goes somewhere instead of just floating
• Every one of the twelve keys is in play: reach past the obvious chords for richer, more surprising color, and it still sounds right
• Build a whole progression, not just four chords: every chord you play lands in your trail, ready to reorder or duplicate to try new versions in seconds
• Pick up right where you left off: your ideas are saved for you
TAKE IT TO YOUR TRACK
• Export any progression as a MIDI file and drop it into BandLab, GarageBand, or any DAW that opens MIDI, then play it through any instrument you like
• Export to iReal Pro format to keep a chord chart or practice over the changes
• Harmonaut Pro unlocks MIDI export, iReal Pro export, and unlimited saved progressions
IT SOUNDS GOOD FOR A REASON
Every chord is voice-led from the one before it, live, as you play: the notes move the shortest way, so a progression flows instead of jumping around. That's the finished feeling you hear in the songs you love.
Push Intensity and the voicings open up: lush 9ths, bright 13ths, and altered dominants like G7#9b13, the colors session keyboard players reach for.
And Harmonaut names every chord the way musicians actually write it, like Ebmaj7, so you can hand your progression to a session player, a bandmate, or a producer and they'll play it back exactly, first time.
No box to buy, nothing to charge, no menus to dig through. It's already in your pocket.
Whether it's your first progression or a sound you can hear but can't name, Harmonaut meets you where you are.
