Description
Frequency Generator - Audio Tools & Ultrasound is an app designed for people who would rather fill their ears with a steady tone of a chosen pitch than with the distracting noise around them. It can help you settle into a productive work rhythm, focus on tasks faster, calm your nerves, step away from stressful surroundings, and even drift off to sleep more easily. The app lets you manually create and fine-tune every parameter, so take your time setting the values to avoid landing on a harsh or irritating tone.
