Would you believe someone if they told you that a ring could help you solve your sleeping problem? Probably not. But that’s the pitch that Finnish tech startup ŌURA is claiming.

ŌURA recently invented the ŌURA Ring, a “ring-sized wellness computer.” The device is designed to help the wearer recover their sleep, Chief Technological Officer Kari Kivela told The Toggle. The ŌURA Ring continuously measures the wearer’s pulse waveform, the exact time between heartbeats and body temperature, translating that information into the corresponding ŌURA smartphone app and using it to create a sleep profile for the user.


The ŌURA also has the ability to track a number of fitness related metrics, but Kivela says that the device was never supposed to be the next big fitness tracker. According to him, ŌURA is “more interested in helping people understand their sleep and energy than in creating a fitness product.” That’s why the Finnish startup recently announced that they were teaming up with organizations like crowdsourced healthcare advice company Curious to answer key questions about sleep patterns and habits. They’re also doing their best to design the ring so that it fully fits the goals and desires of sleep scientists.

This mixture of sleep and fitness data allows the ŌURA app to create what they call a “readiness score.” This score is described by ŌURA as “a simple measure designed to help you identify days that are ideal for challenging yourself, and those that are better for taking it easy.” The ŌURA app gathers all of the sensor data, physiological signals, sleep and activity patterns, then turns them into a percentage that reveals the user’s “readiness.”


But why did ŌURA choose a ring? ŌURA founder Petterri Lahtela says that it wasn’t intentional. He told The Blueprint that they “tested everything available in the market. We found that even though most of those products have some great features, none of them could conveniently provide the kind of data we needed, especially in long term use.” This led Lahtela and his team to begin experimenting with a variety of body sensor prototypes, including ear and finger sensors. They found that the ring was the most effective, most comfortable and (unsurprisingly) most attractive of their prototypes, and moved forward with it.


ŌURA has taken a rather unique approach to getting their product in front of the eyes of funders. They presented it at numerous tech conferences before creating their Kickstarter campaign. The product received mostly positive feedback from tech sites, like Wareable and Gadfit, who praised the device for mixing comfort with a high level of functionality.

ŌURA recently finished their Kickstarter campaign, which raised more than $650,000 in pre-orders, a record amount for a wearable device on Kickstarter. Potential users aren’t able to order the device as of the end of the campaign, though Kivela told The Toggle that they were currently working on building a pre-order system that would let users purchase an ŌURA for the estimated price of $200-300 a ring. Ridding yourself of a sleep disorder might be as simple as just putting a ring on it.
