iPhone

Play a sustained drone note to practice intonation against. This app plays sustained, hand-tuned drone notes that fill the room with deep ambient resonance. Pick any pitch across the full chromatic range and hold it as long as you need — no loops, no seams, just a perfectly steady note with warm overtones. Blend waveforms, soften the attack, and dial in detuned layers to shape the texture. Set a gentle fade timer and let a single tone carry you into stillness. Background audio, AirPlay, and headphones — your drone keeps glowing wherever you go. Perfect for meditation, breathwork, deep focus, sleep, and musical practice or tuning. — SUBSCRIPTION — Premium unlocks all features. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Manage or cancel anytime in App Store settings.
