SignalKind Frequency

Discovery Harmony Relaxation

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Ninety tracks. Ambient music plus pure binaural, Solfeggio, noise and nature frequencies. Free for 14 days, then monthly, annual or one off. Milestones stay free. Signalkind Frequency. Discovery. Harmony. Relaxation. Sound has a measurable effect on the brain and body. Signalkind Frequency turns that time-honoured tradition into a calm, beautiful listening library for focus, relaxation and sleep. No feeds, no noise, no accounts. Press play, that's all there is to it. NINETY TRACKS, TWO PATHWAYS Five ambient music collections: • Focus — Gamma (40 Hz) and SMR (14 Hz) inspired ambience for deep work and study • Calm — Alpha-band (10 Hz) daylight pads and sanctuary rain. Free, forever • Reset — Theta-band (7 Hz) soundscapes and releasing 396 Hz tones for meditation • Sleep — Delta-band (4 Hz) drift for deep, restorative nights • Uplift — traditional Solfeggio tunings (432–741 Hz) woven into warm piano light Seven pure-frequency sections, produced to studio spec (48 kHz WAV): • Brainwave Entrainment — precision binaural beds at 40, 14, 10, 7 and 4 Hz • Traditional Frequencies — exact drones across the full 174–963 Hz scale • Noise Colours — calibrated white, pink, brown, grey and blue noise • Nature — ocean, rain, forest, fireplace and thunderstorm soundscapes • Mindfulness & Traditional — singing bowls, tuning forks, drones and sacred space • ADHD Presets — Hyperfocus, Flow State, Deep Work, Anxiety Reset, Executive Function • Isochronic Layers — speaker-friendly pulse layers at the five key rhythms Binaural tracks are labelled "stereo headphones required" right on the track — the beat needs one channel per ear. Isochronic, noise and nature work anywhere. Every track wears its frequency openly — the band, the hertz and the purpose — and science-based content is always labelled apart from mindfulness tradition. Honest about the evidence, kind about the heritage. Two paths. One purpose. A PLAYER THAT GETS OUT OF THE WAY • Full-screen player with cover artwork and live waveform • Background playback, lock-screen controls and AirPlay • Sleep timer — 15 minutes to an hour, ending in a gentle fade rather than a cut • Playback speed from 0.75× to 1.5×, with 15-second skips either way • Shuffle, repeat, favourites and a searchable library • All ninety tracks bundled inside the app — no streaming, works completely offline SIGNAL POINTS, KEPT QUIET Earn SP for the time you give yourself — minutes listened, tracks discovered, favourites kept and days you showed up. Levels, milestone badges and shareable award cards mark the journey. Not a streak to defend — a rhythm to notice. THE GUIDE: THE SOUND, THE PURPOSE A fully written, explorable guide: how the sounds are made (binaural beats, isochronic tones, noise colours, nature masking), every band and tone in the master frequency library, and how to listen well. PRIVATE BY DESIGN Your listening history, favourites and Signal Points stay on your device. No account, no analytics, no tracking. Nothing leaves your iPhone unless you share it yourself. KEPT LOW, ON PURPOSE We priced Signalkind Frequency to be reached, not gatekept. • Monthly — £2.99/month with a 14-day free trial • Annual — £19.99/year with a 14-day free trial (under £1.70 a month) • Lifetime — £29.99 once. Pay once, keep it for good Everything is open for your first 14 days. After that, one simple choice: monthly, annual, or pay once and keep it for good. And whatever happens, the Milestones and Signal Points you have earned stay free forever. Signalkind Frequency is a companion for focus, relaxation and sleep. It is not a medical device and does not replace professional care. From the makers of Signalkind, the calm self-reflection app. Clarity. Kindness. Intelligence.
