## What is TUO Life?

Begin your journey to better sleep, more energized days, sharper focus and improved mood with TUO Circadian Smart Lighting.

TUO is partnered with the University of Washington, one of the world's top research centers for vision and neuroscience. Scientists there have recently discovered amacrine cells in the eye. These highly light-sensitive cells are the cells that TUO's patented, industry-leading technology affects to influence your circadian rhythm. TUO is more effective than anything else on the market and is the only circadian light therapy product that works at normal brightness levels and reasonable distance.

Put TUO bulbs in your bedroom to get exposure when first waking. Put TUO bulbs in your bathroom to get exposure during your normal morning routine. Put TUO bulbs in your kitchen, and make your family breakfast while getting exposure. Put TUO bulbs on your desk, and check email while taking in light. With TUO, you need to stay within six feet of your light during the majority of your Wake mode. After that, you don't need to worry. Just continue your daily routine, and get the light that you need.

Artificial lighting isn't healthy. Our bodies receive signals from the lighting around us. These signals set our internal clocks and regulate when we naturally sleep and wake. When we're exposed to general home and work lighting, we don't get the signals that we need to keep our biological schedule synchronized with our daily schedule.

Circadian rhythm disorders are problems that occur when your body's internal clock is out of sync with your environment. Symptoms include excessive sleepiness, insomnia, reduced alertness, impaired decision making, poor school/work performance, elevated stress, inability to meet social obligations, changes in appetite and gastrointestinal function, reduced cardiovascular performance, reduced libido, substance abuse, weight gain, high blood pressure and depression.

Prolonged misalignment between your biological schedule and your daily schedule puts you at higher risk for heart disease, obesity, diabetes, gastrointestinal problems, neurodegenerative disorders including dementia, skin issues and more.

TUO Circadian Smart Products synchronize your biological schedule to your daily schedule by providing the light signals your mind and body need throughout the day. The TUO Life App sets a customized schedule based on your age, chronotype and general wake and sleep times so that you can set it and forget it. TUO Circadian Smart Bulbs change to the right mode  at the right time automatically and can be used in any room. Our morning WAKE mode will give you a boost of energy to kickstart your day. Our all-day ACTIVE mode will keep your focus sharp throughout the day. Our evening CALM mode will help you wind down and fall asleep naturally.

GETTING STARTED

Launch our app and click sign up to get started. Follow the instructions on the screen to walk through initial setup and add your bulbs. You'll be asked to allow the app permissions throughout the setup process. Make sure you allow all permissions as we won't be able to setup your bulbs without them.

Add your family members so that they can benefit from TUO as well. When you add family members, our app generates a customized circadian schedule for them. You can give them app login rights or control bulbs on their behalf. You can also assign them rooms so that those rooms always run on their schedule.

Add on/off schedules to fully automate your TUO experience. On/off schedules let your bulbs automatically come on and turn off throughout the day. These can be configured for individual rooms and can be different for different days of the week. This allows your lights to automatically come on when you want them to.

Use the app to turn rooms and individual devices on and off. Change your light brightness and color temperature to match your preferences. Override your circadian modes at any time. How you use TUO is solely up to you.

### 2/5 — Great product but poor app

*2026-07-29, version 4.0.8*

Love my TUO light, but the app is poorly maintained. It is buggy often and consistently logs you out upon closure of the app. If the app was more functional I would recommend a TUO light to more people, but it’s hard to recommend with such a buggy platform.

### 1/5 — Terrible User Interface

*2026-07-08, version 4.0.8*

Very poorly designed app with a lot of bugs.

### 5/5 — Use and Support

*2026-06-15, version 4.0.8*

With a newborn, getting the right lighting is absolutely crucial and with Tuo Life I get that and more. I had an issue and they were so quick with helpful insight, I couldn’t be happier.

### 2/5 — Glitch

*2026-04-23, version 4.0.8*

Glitches too often. It shows the bulb is connected, but you have control. Have to close the application and reopen to make it work.

### 1/5 — Very buggy

*2026-03-20, version 4.0.8*

Lamp doesn’t turn on automatically, app loses connection to bulb and it needs to be reset by entering the WiFi password, app crashes. I can’t manage my circadian rhythm if the light won’t turn on in the morning at the designated start time.

### 5/5 — Amazing change in sleep quality

*2026-01-24, version 4.0.8*

As a neurosurgeon I have to optimize the sleep I can get w my career. This really changed my quality of sleep and allowed me to set circadian rhythm even if waking up before sunrise every day. Game changer. Huge health benefits. Thank you for making this.

### 1/5 — Clunky

*2026-01-20, version 4.0.8*

App is clunky, functionally limited. Requires repeated logins which is annoying.  Bulbs are also buggy. Cool idea, but tech/qc seems to need improvement. Wouldn’t buy again until these issues are resolved.

### 1/5 — Terrible app that needs to redesign

*2026-01-16, version 4.0.8*

Terrible app. I hope the light of itself is a lot better than this stupid app.

### 4/5 — Works pretty well

*2025-12-18, version 4.0.8*

For the most part, the app and the bulb work as expected. I like being able to set up the bulb to turn off and on a schedule. It’s a GREAT way to wake up. My only issue is that the app for now functions a little slowly, it takes a bit to load your room and get to the menu, etc. like a couple seconds, but that’s noticeable when most other apps are almost instantaneous. There are also little glitches sometimes, where I toggle the light on or off but the bulb doesn’t turn off. I usually have to close the app and try again to get it to work.

### 1/5 — Aggravating

*2025-11-25, version 4.0.8*

Setting up is infuriating because it will only let you pick 0700 as a wake up and 11 pm for sleep.
