Sometimes, you simply need some white noise to drown out distracting sounds so that you can relax. Whether you are traveling or simply need background white noise at home, the White Noise Lite app from TMSOFT will provide those sounds. Use the speakers on your mobile device to share the white noise with others, or put on headphones for some privacy and make time to relax. This app may also help you if you find yourself having trouble falling asleep or waking up frequently due to sound distractions. The paid version, White Noise, offers additional sounds.
