About EasyTuner

What EasyTuner Is

EasyTuner is a free online instrument tuning platform at easytuner.org. We build browser-based tuners that help musicians check and adjust open-string pitch using reference tones and, when you choose, your device microphone.

Our tools are designed to load quickly, work without installing an app, and stay usable on phones, tablets, and desktop browsers.

What We Offer

Today, EasyTuner includes tuners and guides for:

• Guitar — standard EADGBE and popular alternate tunings such as Drop D, Drop C, Open G, and DADGAD
• Bass — standard E-A-D-G four-string tuning
• Ukulele — standard re-entrant G-C-E-A tuning
• Educational guides on tuning technique, string frequencies, and common alternate setups

How Microphone Tuning Works

When you tap Tap to tune and allow microphone access, pitch detection runs locally in your browser via the Web Audio API. Audio is not uploaded to our servers for tuning analysis.

Reference tones may be streamed from our content delivery network as MP3 files. You can also tune by ear using those tones without enabling the microphone.

Our Approach

We focus on clear targets (note names and cents), instrument-specific fretboard layouts, and practical guides — not generic filler content. EasyTuner is independent and supported by advertising on some pages.

We do not sell accounts, subscriptions, or personal tuning data. For details on analytics and cookies, see our Privacy Policy.
