Six strings.
One accord.
Akkoord is Dutch for chord, and for agreement. A tuner that tells the truth, a chord atlas where six strings agree, and a song builder that gives its reasons. Plain, warm, and quiet by design.
Tuning as composition
“Sing to him a new song; play skillfully on the strings, with loud shouts.”
The Tuner
Truth, for a guitarist, is pitch kept honestly. Craftsmen still use the old word: a wheel is trued, a string is brought true. The tuner is Akkoord’s plumb line, strict to earn the lock, honest about holding it, calibrated to the cent. Skill begins in tune.
The Chords
A chord is six strings consenting to one another: akkoord, agreement, “with one accord.” The atlas teaches voicings as agreements: every root in red, thirds in yellow, fifths in blue, alternate shapes up the whole neck. Set the capo once; the tuner, the chords, and your songs all follow it.
The Songs
Dutch keeps one word, schoon, for clean and for beautiful. That is the aim here. The builder composes verse, chorus, and bridge in any key, explains every suggestion in one honest line, and knows which capo unlocks the open strings. Beauty is order, resolved.
The language, kept
Harmony through order
The look is borrowed, gratefully, from the Dutch designers we admire from a distance: beauty through function, nothing decorative, everything meaningful. Seven colors in the whole app. A grid the fretboard already believed in. And primaries that only ever mean something:
Nothing leaves your phone. No accounts, no ads, no analytics. The microphone is analyzed on-device and never recorded. The privacy label reads Data Not Collected. We like it that way.
Be first in tune
Akkoord is in beta for iPhone now. Invites go to the list first, then the public TestFlight link lands here.
