Nervous System Calmer guides slow, research-based breathing exercises that help your body move from stress to calm. One tap on the circle starts a one-minute cyclic sigh. PLUS EDITION (one-time purchase, no subscription; try it in three free sessions) In a Stanford study (Balban et al., Cell Reports Medicine, 2023), five minutes of cyclic sighing a day improved mood and reduced physiological arousal more than mindfulness meditation.

Tone Generator is a precise frequency and sound generator for your phone. It plays test and reference signals: a single tone (sine wave, square, triangle or saw), a frequency sweep, white, pink or brown noise, beats, separate left and right channels, and up to four tones at once. Every sound is generated live on the device, from 20 to 20,000 Hz with an accuracy of 0.01 Hz. What it is for Free modes Plus edition The free modes work without limits.

Resonance Meditation begins with your own voice. Hum or sing a comfortable tone for twelve seconds and the app recognizes your note. It then tunes the whole session to it: the base tone, its harmonies, the binaural layer and the breathing rhythm. Everything happens on your phone. Your voice is analyzed on the device and never leaves it. There is no account, no ads and no tracking, and the app has no internet permission. What you can do About the sound All tones are tuned to A = 432 Hz.
