Finally, a tuner that respects musicians.
Most tuning apps have become bloated subscription traps. Weekly charges. Full-screen ads before you can tune E2. Locked tunings behind paywalls. Constant interruptions.
Tunerly takes a fundamentally different approach. Inspired by the clarity of tools like Linear and Raycast, Tunerly is built around one singular promise:
- $4.99/week subscription popups
- Full-screen 30-second unskippable video ads
- Requires online connection & tracking
- Drop tunings & bass locked behind VIP tier
- Zero subscriptions. Ever.
- Instant startup under 300 milliseconds
- 100% offline signal processing
- All instruments & alternate tunings included
Everything you need.
Crafted with Apple human interface standards for practice, stage, and studio.
Guitar Tuning
Standard E, Drop D, DADGAD, Open G, Half-step down, and 7/8-string support with harmonic resonance filtering.
Bass Sub-Octaves
Deep low-frequency analysis optimized for 4, 5, and 6-string bass down to low C0 without pitch jitter.
Ukulele & Strings
Preset profiles for Soprano, Tenor, Concert Ukulele, Violin, Viola, and Cello with standard orchestral A440 calibration.
Chromatic Engine
Automatic note identification across 8 full octaves. Ideal for brass, woodwinds, synthesizers, and vocal warmups.
Sub-Cent Accuracy
Hybrid YIN-FFT algorithm written in C++ WebAssembly offers sub-10ms response time and precision within 0.1 cents.
Minimal Interface
Zero visual clutter. Ultra-large typography designed to be readable from 10 feet away while sitting on your pedalboard or music stand.
OLED Black Mode
True pure black theme turns off individual screen pixels, reducing battery consumption during long rehearsals and gigs.
A4 Calibration
Adjust concert pitch reference freely from 432Hz (Verdi pitch) to 446Hz for baroque or chamber ensemble performances.
Fast. Accurate. Reliable.
Engineered with a lightweight Digital Signal Processing (DSP) pipeline that isolates room noise and harmonic overtones, delivering immediate note locks even in noisy rehearsal rooms.
Sub-10ms Latency
Zero lag between pluck and visual pitch feedback.
Overtone Suppression
Ignores natural octave resonance on acoustic instruments.
Stage-Ready Visualizer
High contrast needle visible under direct sunlight.
