About BeeTune: Guitar & Poly Tuner
Why tune string by string when you can strum all 6 at once? BeeTune is the AI-powered polyphonic and monophonic guitar tuner built to check your entire guitar tuning in a single strum.
Inspired by pro stage polyphonic tuner pedals (polytune style), BeeTune listens to all 6 open strings simultaneously through your phone's microphone and instantly shows which strings are in tune (OK) and which ones are flat or sharp in exact cents.
🎸 POLYPHONIC + MONOPHONIC MODES WITH AUTO-SWITCHING • 6-String Polyphonic Mode: Strum all 6 open strings together and inspect every string on a 6-channel studio console. Perfect for a 1-second tuning check before practice or between songs. • Studio Monophonic Needle (<1 cent): Pluck a single string for surgical precision (0.1 cent readout), target frequency (Hz), 6-string session memory strip, and subtle haptic vibration lock. • Smart Auto Mode: Hands-free switching! Strum a chord to open the 6-string polyphonic console, or pluck a single note to switch automatically to the precision needle meter.
🔥 UNIVERSAL AUTO DETECTION + 10 GUITAR TUNINGS Switch effortlessly between standard, drop, and open tunings for rock, metal, acoustic, blues, and fingerstyle: • Universal Auto Mode: Automatic per-string chromatic tracking. • Standard Tuning: E - A - D - G - B - E • Drop D: D - A - D - G - B - E • Eb Standard (Half-Step Down): D# - G# - C# - F# - A# - D# • D Standard (Full-Step Down): D - G - C - F - A - D • Drop C: C - G - C - F - A - D • DADGAD: D - A - D - G - A - D • Open D: D - A - D - F# - A - D • Open G: D - G - D - G - B - D • Low C: C - G - D - G - A - D
🧠BEENET-8 NEURAL ENGINE — FOR ACOUSTIC, ELECTRIC & CLASSICAL GUITARS • Works with Unplugged Electric Guitars: Closed-loop Auto-Sensitivity (AGC) and manual Input Gain boost quiet string vibrations up to 80x while rejecting human voice and room noise. • Built for Every 6-String Guitar: Acoustic steel-string, classical nylon-string, and electric guitars. • 100% Offline & On-Device AI: Zero internet required in rehearsal rooms or on stage. Audio is processed locally in real time and never recorded. • Adaptive Studio UI: Dark (Studio Obsidian) & Light themes tailored for phones, foldables, tablets, and Chromebooks.
