Hertzy
A precision tone studio for iOS — pure tones, binaural beats and isochronic pulses from 90 to 852 Hz, layered over ambient soundscapes for focus and sleep.
iOS SwiftUI Audio iCloud 2025
A tone generator and soundscape mixer, built around a frequency dial rather than a list of presets.
What it does
Three tone modes — pure tones, binaural beats and isochronic pulses — tunable across 90–852 Hz, layered with rain, ocean, wind and white/pink/brown noise. Curated presets cover focus, calm, sleep and meditation, and any combination you build can be saved and synced through iCloud. A sleep timer fades everything out.
Privacy
No accounts, no email, no contacts. Saved tones never leave the device; only anonymous diagnostics are collected.
