Frequently Asked Questions

Information about SuperTune's high-performance audio engine and cross-platform access.

What is Polyphonic tuning and how do I use it?

Traditional tuners require you to pluck each string individually. SuperTune's polyphonic pitch detection analyzes all strings at once when you strum. The visualizer instantly highlights which strings are flat, sharp, or in tune, letting you see which strings need to be adjusted.

Is SuperTune a web app?

Yes and no! SuperTune runs on a proprietary, native C++ digital signal processing (DSP) core compiled directly to WebAssembly. Instead of relying on standard web-audio utilities, SuperTune bypasses browser bottlenecks. This delivers desktop software speed and precision instantly in your browser tab.

How does the Lifetime "Web Pro" cross-license work?

Purchasing Web + Native for a one-time launch fee of $3.99 creates a secure SuperTune account. When the native iOS and Android apps launch, simply log in using the same credentials to automatically unlock all premium features on your mobile devices at no extra charge.

What is the difference between the PWA and native iOS and Android apps?

The PWA (Progressive Web App) runs instantly in your mobile browser and can be added to your home screen for quick offline access without installing from an app store. The upcoming native iOS and Android apps will be downloaded directly from the App Store and Google Play, offering deeper system integration, background audio handling, and optimized microphone input routing directly via iOS and Android audio frameworks.

How do I install SuperTune?

SuperTune is a Progressive Web App (PWA) that installs directly to your home screen or desktop without an app store download. Click the Install Free button in the top navigation bar for step-by-step instructions for your specific browser and platform.

What specific instruments can I tune?

SuperTune features built-in preset banks for acoustic/electric guitar, 4/5/6-string bass, ukulele, violin, cello, and double bass, alongside traditional alternate tunings (like Drop D and DADGAD). Chromatic pitch detection also handles orchestral, brass, and vocal pitch matching.

Can I embed SuperTune on my school or band website?

Absolutely! Embedding SuperTune is 100% free for music instructors, schools, and content creators. Use our interactive Customize Embed Widget builder above to copy the responsive <iframe> code snippet into your site.
