You’re in. Welcome to the OneApp beta.
First, what this is: OneApp is the companion app for OneDevice — a small wellness device that gives off gentle, low tones designed to support things like focus, relaxation and recovery. The app is how you tell OneDevice what to do. Start with a quick voice check-in to see how you’re feeling, or jump straight into a mode if you already know what you want — either way, the device tunes itself to match.
You’re one of a small group testing it on iPhone and Android before it goes live to everyone. Use it like it’s yours, then tell us the truth — that’s how we get this right.
There’s the check-in way, and the straight-to-it way.
Both take under a minute. Which one you use depends on whether you want to know where you’re starting from, or you already do.
Check in, then tune in.
Open the app and answer one question out loud — “How are you feeling?” — for about ten seconds. That gives you a read on where you’re starting from. Then move into a mode that matches, and let OneDevice help shift how you feel.
Best when you’re not quite sure what you need, or you want to notice the before-and-after.
Just pick a mode.
Skip the check-in entirely. If you already know you want an hour of focus, tap Focus Mode and go. Same for Circadian, Meditation, Solfeggio and Bio-Tuning®.
Best when you’re heading into work, into bed, or into anything you’ve done before.
A preset. Tap Focus and OneDevice tunes itself to support concentration. Tap Meditation and it shifts to support winding down. There’s nothing to set up yourself.
The specific low tone the device gives off in that mode, measured in Hz. Every mode is simply a different tone chosen to support a different state. The numbers are there if you’re curious — you never need to touch them.
Circadian
Follows your day on its own, morning through night.
Focus
60 minutes, for sustained attention and mental clarity.
Meditation
60 minutes, for relaxation and a slower, meditative state.
Solfeggio
Cycles the full sequence, or sit with one tone you choose.
Bio-Tuning®
Your own frequency, if you’ve had it measured with a practitioner.
Every mode is designed to support states like focus, relaxation and recovery. Nothing here treats, cures or diagnoses anything.
Your phone tunes the device by touch.
No pairing, no Bluetooth, no accounts to connect. You choose a mode, your phone taps out a gentle pattern, and OneDevice picks it up and starts giving off that tone.
Hold it flat against the back of your phone, port facing up.
That’s the whole gesture. Keep them together until your phone finishes its short pattern of vibrations — a few seconds — then set OneDevice down wherever you like.
Face it up
Set OneDevice down with the port facing up. The light turns blue when it's ready to listen.
Hold them together
Open OneApp, tap the mode you want — like Circadian — and hold your phone against OneDevice while it transmits.
It turns green
When the light turns green, calibration's done. Set it down and go about your day.
This is what you’ll be testing.
Real screens from the beta build. Try to visit all of these while you’re testing.
Circadian Mode
Shifts with the time of day — morning through night.
Quick & Extended Modes
Start Focus or Meditation in one tap, or open the longer modes.
Solfeggio Mode
Run the whole cycle, or pick a single tone to sit with.
Bio-Tuning® Mode
Enter the personal frequency measured with your practitioner.
Two minutes on your phone.
Pick your phone below — you only need one. Open this page on the phone you’ll be testing with.
iPhone
iOS- Tap the button above on your iPhone and let it install to your home screen.
- Before opening it, go to Settings › General › VPN & Device Management.
- Tap the OneApp developer listing and choose Trust.
- Now open OneApp from your home screen.
That trust step is normal for beta apps — it’s how iPhone handles software that isn’t in the App Store yet.
Android
Google Play- Tap the button above on your Android phone.
- Install from Google Play as you would any other app.
- Open OneApp — you’re ready.
No extra steps here. If Play says the app is unavailable, reply to your invite and we’ll add your email.
Use it for real, then tell us everything.
Treat OneApp as your everyday way to use OneDevice.
Use it regularly — a few sessions a week, in the moments you’d normally reach for the device.
Try more than one mode. At minimum, a Quick Mode and one Extended Mode.
Complete at least one 10-second voice check-in on the home screen.
Notice anything broken, confusing or slow — and send it to us while it’s fresh.
Two minutes, any time you notice something.
Keep the link handy and use it as often as you like — after a great session, after a confusing one, or the moment something goes wrong. You don’t need to wait until the end.
Open the feedback formSomething urgent? Just reply to the invite you received.
