Review momentum

faster than 0% 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 LUMA: Chords in any key
LUMA is a chord synth for iPhone. Pick a key, tap one of seven pads, and play a whole chord that fits. No wrong notes, no theory needed: just progressions under your fingers.
PLAY
• Seven chord pads built from your key, so every chord belongs
• Slide between pads to move from chord to chord
• Chord modes: diatonic, open, jazz and simple voicings
• Synth voices including saw, pad, drone and organ
SHAPE
• Joypad: one hand on filter, pitch bend and rhythmic pulse
• Arpeggiator with rates, patterns and octave range
• Drum loops and a metronome to play along with
RECORD AND CONNECT
• REC captures takes, both the audio and the chords
• Export takes as audio or MIDI files to finish in your DAW
• MIDI OUT over USB and Wi-Fi to hardware synths and DAWs
• Play from a Bluetooth game controller
Made for producers, audio engineers and hobbyists who'd rather play chords than look them up.
