What you can do
Tacet Tinnitus Relief: sound therapy and sleep timer
Tinnitus is loudest when the room goes quiet. Tacet helps you estimate the pitch you hear by ear, builds a sound around it to cover it by day, and plays you to sleep with a timer that fades out instead of cutting off.
Two kinds of sound: masking or notch
Masking concentrates the sound around your frequency so that it covers the tinnitus. The notch removes a band around it instead, so the sound surrounds it. Try both and keep the one that feels more comfortable: what helps differs from one person to another.
A night mode that fades out
A black screen, a clock, and a timer that lowers the sound slowly instead of cutting it off. The sound keeps playing with the screen locked, and stops by itself when you unplug your headphones.
Tacet plays sound and keeps a journal. It does not diagnose, treat or cure anything, and it is not a hearing test. If ringing starts suddenly, especially in one ear, seek medical advice promptly. If it comes with sudden hearing loss, seek urgent medical assessment immediately. Access for new installations requires Tacet Pro through a subscription or lifetime purchase. Prices and any trial eligibility are shown before purchase.

Questions
How does Tacet frequency matching work?
Tacet helps you match the exact frequency of your tinnitus in Hertz, then generates an acoustic notch or a targeted masking sound built around it, so you can cover or work around the ringing without playing loud audio.
Can I use Tacet with headphones while falling asleep?
Yes. Tacet features a progressive sleep timer that gradually fades the masking audio down to complete silence, helping you drift off naturally without a sudden interruption.
Does Tacet work offline?
Yes. All sound synthesis, frequency generation, and audio timers run entirely on your iPhone hardware. You can use Tacet in airplane mode, during flights, or with no connection.
Is Tacet a medical treatment for tinnitus?
No. Tacet is an acoustic comfort tool. It does not diagnose, treat or cure medical conditions. If tinnitus comes with sudden hearing loss, seek emergency medical care immediately. Do not wait for a routine appointment or use an app to delay assessment. For ongoing tinnitus without urgent signs, arrange a medical appointment.
What does it cost?
