About this app

Notefy is a professional-grade instrument tuner designed for musicians who need accuracy without the distraction of advertisements or paywalls. Built with a custom native C++ audio engine, Notefy delivers real-time, low-latency pitch detection for guitars, pianos, and other stringed instruments.
Key Features:
Ad-Free Experience: No banner ads, no pop-ups, and no tracking. Notefy is built for utility, not monetization.
High Precision: Utilizes the YIN algorithm with parabolic interpolation to detect pitch within cents, offering superior accuracy compared to standard FFT-based tuners.
Dynamic Headstock: Unlike static tuners, Notefy allows you to customize your instrument layout. Supports 6, 7, 8, or even 12-string guitars with custom presets.
Piano Mode: Optimized detection for the full 88-key range (A0 to C8), capable of accurately tracking low bass frequencies down to 27.5Hz.
Seismograph Visualization: A scrolling history of your pitch stability helps you visualize intonation and tuning stability over time.
Privacy Focused: The app operates entirely offline and collects no user data.
Technical Details:
Notefy uses a hybrid architecture, combining a modern user interface with a high-performance native C++ layer for digital signal processing (DSP). This bypasses standard system latency, providing a responsive and mathematically precise tuning experience.
Open source and non-commercial. Built by a musician, for musicians.
