## What is Prestant?

Prestant is a tuner built specifically for the pipe organ – precise, fast and reliable even with soft stops. Organists, organ builders and organ consultants tune reeds, flue pipes and mixtures right from their iPhone or iPad. Prestant also handles piano, harpsichord and other instruments with confidence.

PRECISE DETECTION
• Measures to a fraction of a cent – display resolution of 1, 0.1 or 0.01 cents
• From the 32′ pedal (16 Hz) to the very top of the treble
• Picks up soft flutes from a distance, even with the swell box closed
• Calm, easy-to-read display without jumping digits – readable from the console

FIVE DISPLAYS
• Phase and needle free – strobe, spectrum and voicing (harmonic analysis) with "Organist"
• Large note name and cent value at a glance

HISTORICAL AND CUSTOM TEMPERAMENTS
• Pythagorean, meantone (1/4, 1/5, 1/6 comma and more), Werckmeister, Kirnberger, Vallotti, Neidhardt, Schlick, Silbermann and others
• Chart and interval table for every temperament
• Create and edit your own temperaments, freely adjustable concert pitch

BUILT FOR WORK AT THE ORGAN
• Compound stops: measure every rank of a mixture, cymbal, sesquialtera or cornet at once
• Rank by rank, the way organ builders work: the key is detected automatically, all readings in one table
• Tuning pass that advances automatically
• Locking mode: tune relative to a reference pipe
• Celeste mode for voix céleste and unda maris
• Reference tone generator
• Organ projects with divisions, reference pitches and temperature compensation – synced via iCloud across your devices
• Pipe length calculator

FOR THE PIANO TOO
• Piano mode with standard stretch
• Stretch from your piano's measured inharmonicity – as on professional tuning devices (with "Organist")

FOR WIND PLAYERS AND SINGERS TOO
• Calm display: it reads the center of the vibrato, the note name doesn't jump
• Vibrato width at a glance
• Detects organ, piano, wind and voice automatically (with "Organist")

FAIR AND PRIVATE
• Free: the precise tuner with phase and needle display in equal temperament – try everything free for 14 days
• "Organist" (one-time purchase or subscription): strobe, spectrum and voicing, all temperaments, tuning pass, locking and celeste mode, tone generator, measured piano stretch, automatic instrument detection
• "Organ Builder Pro" (one-time purchase or subscription): adds organ projects with temperature compensation, compound stops and the pipe length calculator
• No ads, no tracking, no data collection: sound is analysed only on your device
