Frequency Generator vs Tonscape

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.

Tonscape is a precise sine-wave tone generator and real-time spectrum analyzer in one clean app. Dial in any frequency your iPhone can actually produce — from 0.01 Hz up to the hardware Nyquist limit (around 24,000 Hz) — typed to two decimal places or swept with a logarithmic slider. Set the exact pitch you need, control the volume up to full output, and play a pure, continuous sine tone. Then prove it. The built-in microphone spectrum analyzer captures sound in real time and shows you the full frequency spectrum on a live, neon display. A single-frequency detector measures the exact level at any frequency you choose, and a noise-floor comparison tells you whether that frequency is genuinely present above the background — even faint signals buried in noise, thanks to spectral averaging. WHAT YOU CAN DO - Generate exact frequencies to 0.01 Hz, only the ones your device can truly produce - Adjust volume from silent to full power - See a live, averaging FFT spectrum analyzer with peak-hold - Tap the spectrum to probe any frequency independently of the tone you're playing - Get a clear "present / not detected" readout with dB-over-noise - Identify your iPhone model and its estimated speaker range RELAX & SLEEP (Pro) - Binaural beats and isochronic tones with brainwave-band presets (delta, theta, alpha, beta) - White, pink, and brown noise generators - Nature sounds: ocean, rain, wind, stream, campfire - Sleep timer with gentle fade-out, plus background playback so it keeps going with the screen off - One-tap presets: Schumann/earth resonance, Solfeggio, and tuning references SOUND DESIGN (Pro) - Sine, square, triangle, and sawtooth waveforms - Chords and a logarithmic frequency sweep GREAT FOR - Sleep, relaxation, focus, and meditation soundscapes - Testing speakers, headphones, and subwoofers - Checking whether a specific frequency is present in a room or signal - Audio education, tuning references, and equipment checks Note: binaural beats require headphones. Labels for resonance/Solfeggio presets are descriptive only — the app makes no medical or therapeutic claims. Tiny phone speakers roll off at very low and very high frequencies, so some tones may be inaudible through the built-in speaker even though the signal is generated correctly — use headphones or external speakers for the full range.
