Cudis

CUDIS is a smart ring and health app made by a Los Angeles company. The ring tracks your sleep, heart rate, stress and activity, and it needs no monthly fee. What makes CUDIS different is that it pays you back. You earn Health Points for good habits, and the company has its own crypto token, CUDIS, which launched on Solana in June 2025. CUDIS calls the whole system a "longevity protocol". The idea is that you own your health data and decide who can use it. As of November 2026 the ring comes in four models: Classic, Sporty, Continental and Ceramic.

How the CUDIS ring and app work

The CUDIS ring collects your body data around the clock and sends it over Bluetooth to the CUDIS app on iPhone or Android. The app turns those readings into sleep, recovery and stress scores. An AI coach then suggests what to do next, and points reward you for doing it.

In practice the loop runs like this. You wear the ring overnight, and the next morning the app shows your sleep stages and recovery. The coach turns that into daily tasks, such as a step target or an earlier bedtime. Completing tasks, check-ins and challenges earns Health Points. A September 2026 "Move Week" challenge, for example, paid 5,000 Health Points to everyone who walked 7,000 steps a day for a week.

The app can also pull data from other health sources. CUDIS said in April 2025 that it had integrated more than 70 health data sources. Decrypt reported that the app syncs with Apple Health, Garmin and Oura, so you can use parts of it without the CUDIS ring.

CUDIS ring models and price: 002 Classic, Sporty, Continental and Ceramic

CUDIS sells its ring in four versions. They differ mainly in look and price, as listed on the CUDIS website in November 2026. The Classic is the cheapest, and none of them needs a subscription.

The Sporty went on pre-order through Kickstarter in February 2026. It adds bands you can swap in a range of colours.

According to The Gadgeteer, the Sporty weighs about 3 grams, is rated for pool use and tracks dozens of sports. The battery lasts up to 10 days.

The Ceramic is the newest model. CUDIS announced it on X in late October 2026, calling it "the first smart jewelry". Its price and full specifications were not yet on the CUDIS website.

TechCrunch reported in February 2026 that CUDIS had sold more than 30,000 rings across its first two models.

CUDIS Health Points, rewards and the CUDIS airdrop

Health Points are the rewards you earn in the CUDIS app. You get them for check-ins, sleep, steps, workouts and chats with the AI coach. You spend them in the CUDIS Store. CUDIS says you can swap points for supplements, online doctor visits, recovery sessions and premium features. Its Sporty launch release named store partners in the US, Korea, Japan, Singapore and Malaysia.

Points have also fed into the CUDIS token. When the token launched in June 2025, a first airdrop set aside 50 million CUDIS for early users, according to The Block. CUDIS has also sold limited-edition rings tied to partners, such as World ID and Sui versions.

If you want the ring mainly to earn crypto, read the token and risk sections first. Points and airdrops are set by the company and can change.

CUDIS Age and the AI coach

CUDIS Age is a score in the app that estimates how fast your body is ageing. It compares your body's age with your real age, which CUDIS calls your Pace of Aging. The AI coach uses the score, plus your sleep and activity, to set your daily tasks.

CUDIS added the score in April 2026, based on about 3,100 beta users. The company said most of them improved their score within two weeks, and that physical activity moved it more than any other factor. These are CUDIS's own numbers from its own users, not a clinical study. Treat the score as a wellness guide, not a diagnosis.

The coach does more than give tips. TechCrunch reported that it sets daily tasks, recovery steps and supplement ideas, and can refer you to licensed medical professionals when your trends get worse. In the US, those referrals run through a telehealth network called Klarity Health, per the Sporty launch release. The CUDIS website now calls its AI helper EDAMAME. Decrypt reported in June 2025 that the coach was built on OpenAI's GPT-4o.

CUDIS on Solana: who owns your health data

CUDIS uses Solana so that you, not the company, control your health records. Your ring data is locked with your own keys and shared only when you say yes. Partners who want the data must go through you, and you can be paid for it.

The CUDIS whitepaper lists the parts. A private ID, called LDID, controls who sees what. Your health records become on-chain records that you own. The DataHub is a market where approved partners can buy pooled data with names removed. In October 2024, CEO Edison Chen told The Block that each ring owner gets their own key pair. The locked data is stored on IPFS, a shared file network.

You do not have to use the blockchain side. Chen told Decrypt that you can turn off on-chain storage and still use the app.

Solana is not the only chain. The token launched on both Solana and BNB Chain. In September 2025 CUDIS also expanded to Sui, using Sui's Walrus storage and Seal privacy tools.

CUDIS token (CUDIS crypto): supply, unlocks and exchange listings

The CUDIS token is used for rewards and voting. It went live on 4 June 2025, and its supply is capped at 1 billion. Holders can vote, stake for extra rewards and pay for premium features. Partners use it to pay for data in the DataHub. Live price and market data are on our CUDIS token page.

About a quarter of the supply was free to trade at launch, per the CUDIS tokenomics page. The rest unlocks over time:

The one-year waits ended in June 2026. Since then, tokens for investors, the team, advisors and the treasury have been unlocking bit by bit.

The token launched on Binance, Bybit and Bitget. Some exchanges have since dropped it. CoinEx ended CUDIS trading in July 2026 after a routine check that looks at how much a token trades. Bithumb, a Korean exchange, put CUDIS on a watch list that same month because its value and trading were too low. Korean news site Dealsite reported that Bithumb would end CUDIS trading in mid-November.

CUDIS ring review: who it suits

CUDIS suits you if you want a light, subscription-free sleep and recovery ring and like being rewarded for habits. It suits you less if you need polished software or medical-grade accuracy.

The strongest case is cost over time. The Classic costs $239 up front and nothing after. Oura charges $5.99 a month in the US for full features. If you already track sleep and steps every day, Health Points add a small, concrete return in the form of supplements or services.

Hands-on reviews are mixed. Techloy's April 2026 review of the $399 ring found the battery lasted about two weeks between charges. It also reported Bluetooth drop-outs that needed manual re-pairing, lagging step counts, and an AI coach that gave generic advice. The reviewer concluded that Oura has "more mature apps and more reliable syncing".

The crypto layer is optional. You can ignore the token and use CUDIS as a fitness ring, but then you should judge it as a fitness ring alone.

Is CUDIS legit? Risks and limitations

CUDIS is a real company. It has shipped rings, has named investors and has been covered by TechCrunch and The Block. The risks are in the app, the token and the data, not in whether the product exists.

The app is the most common complaint. Techloy's review found sync drop-outs and an AI coach that could not read the ring's own data when asked. CUDIS Age and the other scores are wellness estimates, so they are no substitute for a doctor.

The token carries real risk. About three quarters of the supply was locked at launch, and it has been unlocking since mid-2026. CoinEx and Bithumb both dropped or moved to drop the token in 2026 over low trading. Fewer venues can mean thin trading and wide price swings, so check the live market data first.

The data side runs on trust. CUDIS says your data is encrypted with your own keys, and you can turn off on-chain storage. We found no public outside security audit of the CUDIS data network. Health data is sensitive, so read the privacy settings before you share it.

The rewards can change. The company sets Health Points, airdrops and what points are worth. Past airdrops do not promise future ones.

CUDIS vs Oura and RingConn

The main difference between CUDIS and Oura or RingConn is the reward layer. Reviewers rate Oura's app as more mature. On price, CUDIS competes with the other subscription-free rings.

Oura is the best-known smart ring, and Techloy's reviewer used it as the benchmark. It needs a paid membership for full features. CUDIS needs none.

RingConn is the closest like-for-like. It also charges no subscription, so the CUDIS price advantage disappears there. The choice then comes down to design, app quality and whether you want points and a crypto token on top.

If you want the most polished sleep tracker, the reviews point to Oura. If you want no fees plus a reward system, CUDIS is the ring built around paying you back for habits.
