NemuTune

NemuTune is a sound app that lets you adjust natural sounds such as rain, streams, wind, and waves, as well as masking sounds designed with everyday noise, conversations, traffic noise, and snoring in mind, to suit your preferences. You can create a sound environment that matches your surroundings and mood, whether you are preparing for sleep, relaxing, or focusing on work. In the free version, you can select and play one masking sound or natural sound at a time. Rain fine-tuning, Solfeggio tones, binaural sounds, and Ambient BGM are also available individually. Free users can also preview Premium “Recommended Mixes” for 30 seconds. Premium lets you mix multiple sounds, directly adjust 8 frequency bands, and save and reuse up to 5 custom sound environments. For the limited-time “Supporter 2026” campaign, users who join Premium during the qualifying period and meet the eligibility conditions will receive Supporter-only perks in a future update. Please use NemuTune at a safe volume that still allows you to hear your surroundings. This app is not intended for medical diagnosis, treatment, or prevention.
