The app

Set it once. Then forget it exists.

You tell OIO about your day, not about color temperature. It runs the whole arc from morning to night ember on its own, following your location's real sunrise and sunset. Drag the simulation to see any hour.

Good afternoon
OIO's got the light. You've got the day.

What it does for you

An autopilot for your light, not another gadget to manage.

Set it once

Tell OIO your wake and wind-down times. That's the whole setup, about five minutes.

The lights run themselves

The day-to-night arc plays out on its own. You never have to open the app for your light to work.

Your circadian coach

Connect your sleep and activity and OIO scores your rhythm and gives you a daily plan to shift it toward your target.

Measure your real dose

The Lab uses your phone's light sensor to calibrate your room and show the actual melanopic dose OIO is delivering where you sit.

Manual when you want it

Override any room, set a scene, or dim to taste. Automation never forces brightness on you.

Your schedule, even inverted

Work nights? Flip the whole arc. The day-to-ember curve moves to your hours.

Yours, not locked in

Works with Alexa, Google Home, and Matter, including local control. You are not tied to one company's cloud.

The circadian coach

It doesn't just run your light. It coaches your rhythm.

Great light is half the story; when you sleep and see it is the other half. Connect your sleep and activity, and OIO's coach turns them into a plan you can actually follow. It lives on the Today tab in the simulation above.

01
Reads your real data

Sleep and activity from Health Connect: Google Fit, Fitbit and more. Nothing leaves your phone.

02
Scores your rhythm

Regularity, timing, duration, amplitude and stability roll into one daily rhythm score and grade.

03
Finds your body clock

Estimates when your internal night falls, so the advice lands at the right hour, not the clock hour.

04
Builds a daily plan

An anchor wake time, a morning bright-light window, a wind-down and a lights-out target, refreshed each day.

05
Nudges, only if you ask

Optional reminders at the moments that matter, and an optional auto-shift that eases your evenings toward your target.

Calibrated delivery

Calibrated at the factory. Measurable in your room.

Every OIO is tuned so the setting you choose delivers the exact spectrum, the same in every bulb. We don't ask you to take that on faith. The app's Lab lets you check the light in your own space, with the phone already in your pocket.

Lab · measure
01
Put your phone where you sit
Its ambient-light sensor becomes the meter.
02
OIO sweeps the room
It steps through off and a few brightness levels, reading the light at each and subtracting everything else.
03
You see your real dose
It reports the actual melanopic light (mEDI) OIO is adding where you sit, calibrated to your room, not a lab bench.
