[Ultra-Precise Strobe Tuner & Acoustic Metronome for Classical Guitar]
Pulsar Tuner is a dedicated tuning and practice app engineered specifically for the acoustic and physical characteristics of the classical guitar.
- Tired of erratic needle tuners that never settle?
- Want to eliminate third-string beating and low-fret sharpness?
- Need a metronome that automatically calculates your playing tempo?
- Wish to review your phrasing hands-free without putting down your guitar?
Pulsar Tuner solves these challenges with professional audio DSP in a lightweight, instant-launch app.

KEY FEATURES
----------------------------------------
1. Ultra-Precise Strobe & Needle Display (+/-0.1 Cent)
- Real-time phase-accumulating strobe display emulating mechanical wheel behavior (clockwise: sharp, counter-clockwise: flat, stationary: in-tune).
- Automatic String Detection: Pluck strings 1 to 6 and tune without touching the screen.
- Auto Snap (SettleDetector): Skips transient plucking noise and automatically locks pitch the millisecond the tone stabilizes.
- Pitch Ribbon: Visualizes pitch trajectory over time with automatic zoom near target frequencies.
2. Dedicated Classical Guitar Tuning Modes
- 12-Tone Equal Temperament (12-ET): Standard universal tuning (0.0 cent offset on all strings).
- Key Optimization: Automatically calculates pitch offsets for major keys (E, A, D) to eliminate 3rd-string beating and purify chords.
- Chord Compensation: Offsets fretting tension sharpness (+2 to +4 cents) on lower frets across open strings.
- Dyad Beat Tuning: Real-time visualization of acoustic beat speed (Hz), period, and modulation depth when plucking two notes together.
3. High-Precision Acoustic Metronome
- Jitter-free audio playback powered by look-ahead buffer scheduling.
- Physical Pendulum Visualizer: Recreates smooth mechanical pendulum swing while minimizing battery drain.
- Acoustic Tempo Detection: Analyzes plucking onsets via microphone to estimate live BPM and apply it with a single tap.
- Flexible Settings: 1-12 beats, subdivisions (quarter, eighth, triplet, sixteenth), and authentic woodblock sounds.
4. String Quality Diagnostics (String QA)
- Detects core flaws and unrounded shapes (unwanted beating) in new strings.
- Objectively scores open-string decay envelopes and harmonic uniformity.
- Measures octave intonation (12th-fret harmonic vs. fretted note) to assess string health and saddle compensation.
5. Hands-Free Loop Practice Recorder
- "Armed" Mode: Monitors the microphone and automatically starts recording upon your first plucking onset.
- Auto Stop & Loop Playback: Detects 2.2 seconds of silence after your phrase, stops recording, and immediately loops playback.
- Evaluate tone, touch, and timing without ever taking your hands off the guitar.
- Export studio-quality audio in WAV, FLAC, or AAC formats.
6. Built for Optimal Performance
- Mic Gain Calibration: Automatically suggests optimal input gain for your device and microphone environment.
- Screen Keep-Awake: Prevents display sleep while tuning so you can focus entirely on playing.
