About the business

Taurus product owner is the Co-founder & CEO of IoTeX, a leading blockchain & IoT platform. IoTeX was founded as an open-source platform in 2017 with a vision for the Internet of Trusted Things. Humans and machines can interact with guaranteed security and trust in this decentralized ecosystem. They are on a mission to ensure everyday people and businesses can own and control their devices and the data/value they generate.

IoTeX will democratize access to machine-backed DApps, assets, and services to deliver user value and fuel the new machine economy by connecting the physical and digital worlds.

Considering the background, it was a natural move to start building Taurus, an app that utilizes "sleep-to-earn" mechanics. The app allows users to earn tokens depending on their sleep score. It's simple: sleep better – earn more.

We started with the Proof of Concept to help our client embody a draft idea into a product with sophisticated mechanics.

Taurus. Oura Ring.

While working on the PoC, we indicated that short-term motivation for users would be to receive financial incentives while long-term – to cultivate a healthy lifestyle.

We aimed to connect the application to the primary wearable health devices. The first device to start from was Oura Ring. This tech jewelry accurately represents nightly sleep quality by screening breath patterns and measuring blood oxygen levels. It perfectly aligns with a mechanics we thought over -- the number of received tokens is calculated depending on sleep quality. Criteria for quality involve sleep duration and phases of deep sleep.

Platform features

For the Proof of Concept, we suggested a short list of features that would make the most sense for users and help us test the hypothesis.


Wallet integration
ioPay multi-chain crypto wallet can be connected


Apple services integration
The app is synchronized with an Apple Health account


IoT devices integration
The app can be connected to wearable health devices like smart rings etc


Enrolment of tokens to the wallet is provided. Visualization of tokens’ enrolment is done with the calendar displaying tokens earned by the day


Wearable health devices
Connection to Wearable health devices such as Oura Ring or Apple Watch

Taurus. Screens.

Platform scaling

During the work, we had a significant backlog of ideas. As we selected priority tasks for the PoC, we also formed the vision of further development direction. Though the features could change during the process, we wanted to focus on functionality that would enhance the audience's engagement with the product.


Build a Marketplace with exclusive NFT objects


Referral program which allows earning tokens for inviting friends


Gamification and achievement system

Visual communication

One of the main goals assigned to Proof of Concept was to embody the product idea in design. We wanted it to look and feel like a valid product. We started design in a few directions, but after Taurus, the naming, was approved, there was no doubt it would get a reference to astronomy. However, we still didn’t want the connection to be too obvious.

The general dark tone of screens refers to the night sky and builds an association with sleep time. At the same time, primary colors contain several bright accents which look native when it comes to Web 3 products. In some way, it also matched Oura's visual identity, the primary device connected to the app.

Proof of Concept helped to present how a business idea works in design & code. As it's said – seeing is believing. Our client aimed to get feedback from two groups: investors and test users. After gaining initial interest and support from both of them, it got clear we built PoC in the right direction. The upcoming big step is to raise the next round of investments and plan the new release and scale the platform.
