The only demo that matters
Words can't carry this. Press both — the same knuckle on the same wood, with and without Tembra.
Best with headphones. This demo is synthesized in your browser — the app does this to live sound, with your actual room.
How it works
Bluetooth is too slow for live sound. The wire is the magic.
Your room answers back as a cathedral.
The space blooms the longer you sit.
The spaces
Slide between them mid-session. The room follows.
Stone, height, and a long amber tail.
Close walls, deep echo, mineral dark.
No walls at all. Sound drifts forever.
Soft ground, living air, birdsong distance.
Slow blue pressure all around you.
Bright facets, glassy shimmer.
The quietest place in the app.
Built for one held note.
Weight below everything.
Open, weightless, morning-lit.
Sound Voice
You hum one note. Tembra tunes itself to you.
Hold one long note. A second line rises to meet yours until the two move as one — and with Choir on, your voice returns a fifth and an octave above. There is no wrong note here.
Recordings
Record a session and share it like a voice message. People usually reply asking what app that was.
Recording is a deliberate act — nothing is captured until you press the ring.
Pulse — the other side of Tembra
Walk up to a speaker. Tembra reads the music and turns its pulse into something you feel in your hand and see in your palm — the phone flashes on every beat. Raise it over your head and it becomes part of the show. No headphones needed.
The full punch. Fast lock, hard flash.
Something softer, still locked on.
A touch. And if there's no beat to find, Tembra says so instead of pretending.
Optional: feel the bass in your headphones, locked to the beat.

Privacy
Sound is transformed on your iPhone and disappears. Nothing is recorded or uploaded unless you deliberately tap Record. No ads, no trackers, no data sold.
Bluetooth adds too much delay for live sound, and speakers cause feedback. The magic needs a wire. Pulse is the exception — it works with nothing in your ears at all.
No. Audio is transformed in real time and never leaves your device unless you explicitly tap Record and share.
Settings → Account → Delete Account. Server-side data is removed within seconds.
