Launch sale — strum real chords with one finger. Four vintage synth voices, five rhythms with auto-bass, and two gorgeous looks. No ads, no subscriptions.
The beloved electronic autoharp of the early '80s — the strum-anything
wonder heard on records by Gorillaz, David Bowie and Brian Eno — reborn
as a pocket instrument anyone can play in seconds.
Press a chord button with your left thumb. Sweep your right thumb across
the SonicStrings-style strumplate. That's it — you're making music. Every
string is always in tune, because the plate re-tunes itself to whatever
chord you're holding.
MADE FOR INSTANT MUSIC
• 12-string touch strumplate with true multitouch and velocity — strum
slow and soft or fast and bright, with a haptic tick on every string
• 108 chords from a 3 × 12 panel: hold Maj+7 for maj7, Min+7 for m7,
Maj+Min for dim, all three for aug, plus Sus4 and Add9 keys
• Four voices — Omni, Harp, Celeste, Organ — from a real-time polyphonic
synth engine with shimmering delay, hall reverb and vibrato
• A sustained chord-organ layer with its own volume fader, for that
warm held-pad-plus-sparkle sound the originals were famous for
• Seven built-in demo songs that play the instrument for you — and a
LEARN MODE that turns every one into an interactive lesson: the song
pauses at each chord change, the keys to press light up, and it rolls
on the moment you play them
• Tape mode: gentle wow & flutter, like a loved cassette
• Left-handed strumplate option
• Record your performance and share it anywhere with one tap
• MIDI out: a "Pocket Strum" virtual source plays GarageBand, Logic,
AUM or hardware synths straight from the strumplate
• Six voices: Omni, Harp, Celeste, Organ, Bell and Pad
A BAND IN YOUR POCKET
• Five rhythms with drums and an auto-bass that follows your chords:
Rock, Slow rock, Waltz, Bossa nova and Hip hop
• Tempo fader from 60 to 180 BPM with a running-beat LED
• Keeps playing in the background and mixes with Apple Music or Spotify,
so you can jam along with anything
TWO LOOKS, ONE INSTRUMENT
• Classic: a cream-and-red hardware skin with bevelled plastic keys,
red LEDs and ruler-ticked faders, straight out of 1981
• Modern: a flat, dark, stage-friendly UI
• Switch anytime — your choice is remembered
HONEST BY DESIGN
• Pay once, own it forever
• No ads, no subscriptions, no accounts, no tracking — the app collects
no data at all
• Works in portrait and landscape on any iPhone running iOS 17 or later
Whether you're sketching songs, adding dreamy texture to a track, or
handing your phone to someone who's "not musical" and watching them light
up — Pocket Strum makes playing feel like magic.
