PureTune is a compact, no-friction instrument tuner that gets you from pickup to playing in seconds — ideal for guitarists, bassists, ukulele and banjo players who want a fast, ad-free experience. The app listens in real time and displays pitch clearly so you can tune quickly without navigating menus, and it works fully offline so you don’t need a connection. PureTune includes dozens of preset tunings, a simple visual gauge and haptic feedback when strings are in tune, plus a small non-intrusive banner to keep the app free.

Development Team

PureTune was created by a solo developer who built the app out of frustration with intrusive tuner apps; they maintain the app personally and welcome feedback to improve features and add requested tunings.
