Get in tune. Stay in tune.
Guitar Tuner: Chromatic Pitch listens through your microphone, detects each string's frequency in real time, and shows you exactly how sharp, flat, or perfectly in tune you are — on a clean animated tuner dial with color-coded feedback.
Whether you're tuning an acoustic guitar, an electric guitar, or a bass guitar, the chromatic tuner catches every note across the full frequency range. Select any string from standard tuning or switch to alternate tunings — drop D, drop C, open G, and more from the built-in database.
🎵 Ear Training Mode
Beyond tuning, the app includes a dedicated ear training panel. Play a reference pitch at any exact frequency, then match it on your guitar to develop pitch recognition. This ear training tool works alongside every practice session — no extra app needed.
🎸 What the guitar tuner does
• Real-time pitch detection via FFT frequency analysis
• Animated needle dial: sharp / in-tune / flat with instant visual feedback
• Note name and detected frequency on screen
• String selector for standard and custom tunings
• Color-coded accuracy — green means you're there
📻 Chromatic coverage
The chromatic engine covers the full scale for every guitar string and tuning configuration. No manual note selection — just play and it identifies the note automatically.
🎧 Build your ear
Generate reference tones at exact frequencies. Practice matching pitch by ear, recognize intervals, and develop the pitch training habit that separates consistent players from inconsistent ones.
Tune accurately. Train your ear. Play better.
