Nevelo

Nevelo is a focused toolkit for musicians: a precise metronome, an accurate tuner, and a chord library — in one beautifully restrained app. No account, no ads, no tracking. Everything runs on your device.

METRONOME
• Sample-accurate, drift-free timing driven by the audio clock
• 30–300 BPM with a tactile tempo dial — swipe up or down to set the tempo
• Tap tempo, time signatures, subdivisions, editable accent patterns, count-in
• A clean, designed click; keeps playing with the screen locked

TUNER
• Real pitch detection — accurate to the cent, no fake needle
• Chromatic mode plus guitar, bass, ukulele, and violin presets
• Manual mode: tap a string to hear an instrument reference tone and tune by ear
• Adjustable reference pitch (A4 415–466 Hz)

CHORDS
• Hundreds of voicings for guitar, ukulele, and piano
• Clean, print-quality diagrams with alternate positions
• Hear any chord played with a warm acoustic tone

PRIVATE BY DESIGN
• No account, no servers, no analytics, no third-party SDKs
• The microphone is used only for the tuner and is processed entirely on-device — never recorded or sent anywhere

Designed for iPhone, with full VoiceOver support, Dynamic Type, and Reduce Motion.
