ACRN-Tinitus Relef is a science-backed app that uses Acoustic Coordinated Reset Neuromodulation (ACRN) to help relieve chronic tinnitus. What is ACRN? Tinnitus is fundamentally a condition of the brain and nervous system — not just the ears. ACRN is a cutting-edge physical therapy that "resets" the auditory cortex by reshaping abnormal neural connections. By delivering precisely timed tones around your tinnitus frequency, the therapy gradually desynchronizes the overactive neural firing patterns responsible for the ringing in your ears. How to Use Visit a professional audiology clinic to determine your exact tinnitus frequency (in Hz). Set the matching frequency in the app (1,000–10,000 Hz). Listen for 4 hours daily over several weeks for long-term relief. Key Features Single Mode — Play a continuous ACRN tone sequence for one-sided tinnitus. Adjust frequency from 1,000 to 10,000 Hz. Split Mode — Set independent frequencies and volumes for your left and right ears, ideal when each ear has a different tinnitus pitch or loudness. Evidence-Based — Built on peer-reviewed ACRN research (PMC4362296). Light / Dark / Auto Theme — Comfortable to use any time of day. Built-in Tutorial — Step-by-step guidance on ACRN therapy, how to find your tinnitus frequency, and how to get the most out of the app. Important Notice This application is not a substitute for professional medical advice, diagnosis, or treatment.
