A LITTLE AWARENESS GOES A LONG WAY

Your space has a rhythm.
Get to know it.

01

Read the room

Start listening. After 20 seconds, get a Calm Score based on speech-like sound, sudden noise, and approximate sound level.

02

Keep the useful bits

Stop listening to save the reading to a named room. The audio is discarded; your scores and history stay in the app.

03

Find your moment

Compare rooms and return at different times. As readings build up, see which spaces and times tend to be calmer.

Calm Scores are estimates, not medical advice or certified noise measurements. Your own comfort matters.

TONE STUDIO · FREE

Find your frequency.
Make it your own.

Every Tone Studio control is free, with no microphone, account or subscription needed. Choose a preset or dial in your own, layer a soft background underneath, and set it to stop on its own.

  • Presets from 174 to 963 Hz, or any custom frequency from 20 to 2,000 Hz
  • Pure, binaural or pulsed tones, with beat presets from 2 to 20 Hz, Schumann 7.83 Hz among them
  • Brown, pink or white noise underneath, each at its own volume
  • Timers, saved mixes, and multi-step mixes that move through frequencies in sequence

Frequency describes pitch; no health benefit is claimed. Binaural beats need stereo headphones. Start at a low volume.

MAKE ROOM FOR A PAUSE

A simple ritual.
On your terms.

Time to settle

Unguided focus timers from 5 to 30 minutes. Focus time, and the multi-step mixes you sit through, count toward your daily goal, even without microphone access.

Sound to wind down

Brown noise, pink noise, low-frequency sound and ambient tones, with sleep timers and fades. Optional with Low Key Mode+.

Progress that stays yours

Build a streak with measured calm time or focus timers. Earn six distinct soundscapes at milestones, from steady rain to distant thunder, yours to use without a subscription.

A MICROPHONE. NOT A RECORDING.

Your room.
Your business.

Sound is processed on your device and discarded. Low Key Mode estimates speech-like activity; it does not transcribe conversations or identify speakers.

  • No account or sign-in
  • No audio saved or uploaded
  • No advertising or analytics SDK in the app
  • Optional Apple Health saving, off by default
