StroboPro is a multi-harmonic strobe tuner with harmonic rings that track every overtone on a bright, easy-to-read display. Grab it as a quick guitar tuner at home, a chromatic tuner for violin or bass on stage, or a precision tool for piano tuning and intonation work. Move beyond "simulations" and embrace the authenticity of harmonic tracking with StroboPro. No other mobile tuner app visualizes the harmonics of your instrument like StroboPro; our unique algorithm tracks each harmonic in real time, providing a complete picture of your tone. Start your tuning journey with our straightforward cents display to get close to the perfect pitch, then use the harmonic rings to dial it in. Works great for guitar, bass, piano, violin, viola, cello, banjo, ukulele, mandolin, and more. Features that Set Us Apart: - Independent harmonics: captures and displays each individual harmonic of your instrument, with each harmonic ring tracking an individual harmonic. Display up to 10 visible harmonics at once. - Dynamic, high-contrast, high-fps display. - Automatic Pitch Detection: StroboPro detects pitch automatically, so your instrument ends up perfectly in tune. - Intelligent Background Noise Filter: Unwanted background noise is filtered out for a clean tuning signal. - Built-in Pitch Pipe: Generate reference tones for ear training or quick tuning checks, with a Sine waveform (includes a harmonics mode). - Precision: less than 0.1 cent display resolution, with accuracy that holds on low-frequency notes for low-register instruments. - Supports numerous guitar tunings including dropped tunings, 4-string, 5-string, 6-string, and more. - Piano Tuning Assistant (Beta): Measure how string stiffness shifts each partial (your piano's inharmonicity) and generate custom tunings for a perfect stretch across the entire keyboard. - Reference Stretches: Choose from well-known piano stretch curves from recognized standards. - Share Custom Tunings: Send your custom tunings to other musicians via a simple link. - Echo Mode: Audio-first tuning guidance designed for visually impaired users. The app listens for your pitch and plays a guiding tone to the target. - Accessibility built in: a large, high-contrast display, full screen-reader/VoiceOver labels on every control, and Echo Mode for hands-free, audio-first tuning. - Automatic noise suppression ignores continuous background noise. - Advanced users will appreciate the Note Lock. - Note Lock lets you target specific notes and individual harmonics, even in loud environments. Supports presets like True Temperament and Adler SubContra Bass. Create your own tunings with AI and back them up in your cloud account (Premium). What Musicians Say: "I play steel guitar with 3 necks. This is my absolute favorite tuner available. Easy to use. Nothing silly, it just works and is super accurate. I retired my old tuner after I got this app. I've tried many other tuner apps and this is the best." - B Sheeley, steel guitar player "Finally a tuner that doesn't suck! A modern interface. Precise. It just opens the tuner directly without any ads." - Leonardo M "This tuner is certainly the best one you can get on the market. I've tried quite a few, this is my go-to, I couldn't get along without it." - Bruce C. "I am pro piano tuner and had many tuner softwares. This is so far the most clean and neat interface I have ever seen. Some software cost almost one thousand dollars but ugly old interface." - Tony Z, Pro Piano Tuner "I've been playing guitar since I was eight. I am now 69. I love this tuner." - Gazorbo We Value Your Opinion Your feedback and reviews are crucial to making StroboPro one of the best tuning apps for musicians on iOS. Privacy: We don't collect your data.
