Bourdon vs PanStrobe

Bourdon is a precise, beautifully simple string tuner for a wide range of instruments. It tracks pitch with a professional algorithm (McLeod/MPM) plus phase refinement that reaches sub-cent accuracy on sustained notes, responding instantly even in noisy rooms — all in a clean, minimalist dark design. FIVE MODES IN ONE - Needle: an analog VU meter with a damped needle, for the classic tuning feel. - Trace: string-by-string tuner with a smooth visual trail and a real headstock that turns green as you go. - Strobe: the most precise mode. The stripes freeze when you nail the note, down to fractions of a cent. - Voice: a free chromatic vocal tuner — or set a target note and practice until you nail it. - Drone: a sustained reference tone (warm organ timbre) using your tuning's notes, perfect for singing or tuning by ear. 15 INSTRUMENTS, MANY TUNINGS - Guitar, classical, 7- and 12-string, baritone, 4- and 5-string bass, double bass, ukulele, violin, viola, cello, mandolin, banjo and bouzouki. - Tunings such as Standard E, Drop D, Drop C, half- and whole-step down, DADGAD, Open G/D/E and more. - Each instrument with its own headstock, so you always know which string you're tuning. TWEAKS FOR MUSICIANS - Temperaments: Equal, Pythagorean, Just Major, Kirnberger III and Quarter-comma Meantone. - Adjustable A4 reference (432–446 Hz). - Normal and Ultra precision. - In-tune confirmation with sound and haptics. PRIVATE AND OFFLINE - All processing happens on your device. Nothing is collected or uploaded. Tune your way. String by string.

PanStrobe is a harmonic strobe tuner built for handpan makers, tuners and players. A handpan note is not one frequency — it is a fundamental with an octave and a compound fifth tuned above it. PanStrobe shows all of them at once as true strobe motion: each ring is one partial, position is phase, and drift speed is exactly how far off you are. When a ring stands still, that partial is in tune. TUNE BY SIGHT • Half-circle strobe disc or horizontal strobe rows — one band per partial • True strobe physics: left = flat, right = sharp, stillness = in tune • Live cents readouts with glitch rejection — and no averaging: the wobble you see is real signal • Strobe divisors (÷2, ÷3, ÷5) slow the pattern for far-off notes HEAR THE WHOLE NOTE • Real-time spectrum with a piano-key axis and labelled peaks • Waterfall view: watch each strike's harmonics evolve over time • Automatic note detection, or lock to the note you are working on BUILT FOR THE WORKSHOP • Chromatic notes with octave control, adjustable A4 reference, global cents offset • Band editor with multi-partial templates (1:2:3 and more) • Pitch pipe on every band — double-tap a strobe for a reference tone • Dark, glare-free UI designed for metal shops • Works fully offline — audio never leaves your device, no account, no tracking FREE TRIAL, FAIR PRICING Every install starts with a full-featured 8-day trial. After that, the free tier stays a single-band chromatic strobe tuner. PanStrobe Pro adds what the app is really for — every partial of a note at once, the spectrum analyser, the band editor and the pitch pipe — monthly, or yearly at about 20% less. Made by Panlab — we build and tune handpans in Hong Kong. This is the tuner we use ourselves.
