Frequency Generator vs RetroTone

Frequency Generator turns your iPhone into a precise, studio-clean tone source — for sleep, focus, relaxation, and sound exploration. Dial in any frequency from a deep 1 Hz rumble to a 22,000 Hz shimmer, shape its character, and press play. WIND DOWN AND SLEEP Mask traffic, chatter, and a restless mind with smooth white, pink, or brown noise. Start it playing, lock your phone, and let it run all night in the background. FIND YOUR FOCUS Drop into deep work with binaural beats and isochronic tones, or let steady noise blur out distractions around you. Made for studying, writing, and long concentration sessions. RELAX, MEDITATE, RESTORE Play the tones people reach for to unwind — including 432 Hz, 528 Hz, and the full set of Solfeggio frequencies — as a calm backdrop for meditation, breathwork, or simply slowing down. PLAY ANY NOTE Sound any pitch across nine octaves (C0–B8) as a clean reference tone, and set your concert pitch anywhere from 432 to 446 Hz. Ideal for tuning by ear, training your ear to intervals, or checking a note on the fly. EXPLORE THE FULL SPECTRUM Sweep all the way up to 22 kHz to hear the high and ultrasonic frequencies your ears, headphones, and speakers can reproduce. Shape the timbre with sine, square, sawtooth, or triangle waveforms. PRECISE, EFFORTLESS CONTROL Set an exact frequency down to the hertz, fine-tune it on a smooth slider, and switch sounds instantly. No clutter, no setup — just the tone you want, the moment you want it. PICK UP WHERE YOU LEFT OFF Every tone you play is saved to Recents. Pin your favorites, give them names, and replay any setup with a single tap. KEEPS PLAYING Full background audio with lock-screen and Control Center controls, so your sound stays with you while you get on with everything else. Frequency Generator is free to use, with an optional Pro upgrade that unlocks every waveform and noise color, binaural beats and isochronic tones, and the Solfeggio and musical-note presets.
