PureWaves

PureWaves generates real binaural beats — pure tones, nothing else. Most binaural beat apps mix the tones with rain, ocean waves, or ambient pads. PureWaves doesn't. Just the two tones your ears need, so the beat frequency reaches your brain exactly as intended. FIVE BANDS, FIVE STATES • Delta (0.5–4 Hz) — deep sleep and recovery • Theta (4–8 Hz) — deep meditation and creativity • Alpha (8–13 Hz) — relaxed calm, wide awake • Beta (13–30 Hz) — alertness and active focus • Gamma (30–100 Hz) — sharp focus, peak performance A REAL SYNTHESIZER, NOT A PLAYLIST Every tone is generated live by an audio oscillator — nothing is pre-recorded. Watch the actual waveform on a live oscilloscope display, and fine-tune the base frequency, beat frequency, and volume with synth-style knobs. Move a knob and it always springs back to the frequency chosen for that band, so you can explore without losing the intended effect. HOW TO USE IT Stereo headphones are required — binaural beats only work when each ear receives its own tone, and speakers mix the two together in the air. Wired headphones give the cleanest, uncompressed signal. Sessions of at least 15 minutes work best, and the effect builds with consistent daily use over about a week. PureWaves is free to try for 24 hours. Unlock it once for a small one-time payment — no subscriptions, and every future update is included for free.

Verdict
The clearest difference is ads: PureWaves at none against Sleepzy's shown. PureWaves also leads on update cadence (every 10 days vs monthly). Sleepzy's advantage is device support (4 vs 2) and iOS requirement (13.0 vs 16.0). On price and in-app purchases there is nothing between them.
