A custom sleep app, built around your own brainwaves

The product

myWaves is a sleep-support service. Members record a night of sleep with a small EEG recorder worn on the forehead, upload it, and a patented algorithm turns their brainwave data into a sound made just for them. They listen to it for 30 minutes before bed.

Sun Digital Health, a subsidiary of Sun Corporation, launched it in Japan as its first digital-health product, sold as a kit with the recorder, headphones, and a subscription.

What we built

An independent custom build, designed by us: the mobile app members use every day, the server behind it, an admin for Sun Digital Health's own team, and an enterprise portal for doctors and clinics. The brainwave processing that creates each sound is myWaves' own technology; we built the product around it.

The hardest part was getting the experience right for Japan. Members are consumers, not engineers, working with an EEG recorder at bedtime, so every step had to feel simple and natural in Japanese.

What the app does

The app is where members live with the service day to day:

• A sleep score with a weekly chart, so members can see the trend, not just last night
• Listen: play your personal sound before bed
• Measure and upload: record a night and send it in for your next sound
• A sleep diary, plus short guides on the science of sleep and getting started
• Japanese throughout, for the Japanese market

How we work together

myWaves is live in Japan. It is a custom build, not an app on our platform. It runs on AWS, where Sun Digital Health stores user information and brainwave data separately, encrypted and anonymized, under Japan's privacy law (APPI). The code belongs to the client. See who owns what.

It is a good example of the other half of what we do: software we build for a client who needs to own it.
