Harmonizer Focus plays calm tones to help you settle into your work, unwind or drift off to sleep. No account, no ads, no fuss: pick a mode and start.
Two tones, one rhythm
With headphones, each ear hears its own tone. Together they form a gentle rhythm: a binaural beat. On a speaker or bone conduction headphones the app uses isochronic tones, which work without headphones.
Three modes
• Focus: for deep work, with a short lead-in.
• Rest: to unwind or meditate.
• Sleep: slowly glides to a calmer rhythm and fades out by itself.
Tuned to your headphones
The app recognises the headphones you connect and suggests the right profile: over-ear, in-ear, bone conduction or speaker. Your choice is remembered per device. If mono audio or spatial audio is on, the app warns you, because those settings change what you hear.
Sound in the background
Add pink or brown noise, rain, wind, rain on a window, waves or birds underneath, each at its own level.
Made to keep playing
Sessions keep playing with your screen locked and pause by themselves for a phone call or when your Bluetooth headphones disconnect.
Privacy
Everything stays on your device. The app collects no personal data and does not connect to our servers.
Good to know
