Sekonda has joined a growing list of companies selling wearable rings, introducing a first smart ring at £79.99 that promises multi-day battery life and health tracking without a paid subscription. Its arrival matters because it puts inexpensive hardware into direct competition with established products from Oura and Samsung, and raises fresh questions about accuracy and data practices.
Sekonda’s entry: features and price
The British watchmaker’s ring monitors heart rate, sleep, skin temperature, stress, steps and menstrual cycles. The device is rated water-resistant to 50 meters (164 feet), advertises up to seven days between charges, and is sold without a monthly fee.
At roughly US$110 equivalent, Sekonda’s offering sits far below premium options, and well inside the price range of many impulse buys available online. That positioning makes it a useful test of how much value today’s low-cost hardware can deliver.
Why the finger is a good place for sensors
Rings typically rely on photoplethysmography, or PPG, which measures changes in light caused by blood flow beneath the skin. Fingertips supply a strong optical signal because blood vessels lie close to the surface — the same reason clinicians clip pulse oximeters to fingers.
Miniaturized optical sensors, accelerometers and temperature chips can now fit inside a piece of jewelry small enough to be worn continuously. That unobtrusiveness makes rings particularly well suited to overnight monitoring, when watches are sometimes taken off.
What rings can and cannot do
Nightly tracking lets rings spot trends across many sleep cycles rather than capturing occasional snapshots. That collective data is where their practical value tends to appear.
But limitations remain. A 2026 systematic review of 28 studies reported about 87% accuracy when distinguishing sleep from wakefulness. Accuracy for specific sleep stages was lower: roughly 65% for light sleep, 81% for deep sleep, and 74% for REM. In short, rings are useful for pattern detection, but they don’t replace a clinical sleep lab.
Price tiers and the importance of software
High-end products still command premium prices and ecosystem services. Oura’s Ring 4 starts at US$349 and pairs with a subscription that costs US$5.99 per month or US$69.99 annually in the U.S. Samsung’s Galaxy Ring entered mainstream retail at about US$399.99 and launched in Australia at AU$699; Samsung does not require a subscription for its health data.
Cheap sensors can deliver a heart-rate number, but translating streams of raw readings into reliable insights — about recovery, stress, or sleep quality — depends on mature algorithms and thorough validation. A separate review of smart-ring research found encouraging clinical results but also flagged moderate-to-high risks of bias in many studies and warned that proprietary algorithms limit independent evaluation.
Data flows and privacy considerations
Sekonda markets its product as having “no subscription ever,” but its privacy policy indicates the ring’s recorded data is uploaded to the company’s servers when synced. Types of data listed include heart rate, activity, sleep and location, and Sekonda says such data may be processed by affiliates or service providers and transmitted to countries including Germany and Hong Kong.
Users can reportedly withdraw consent and request deletion through the app, but that process still starts after data has left the device. Importantly, cloud processing is a design choice rather than a hardware necessity.
Open-source projects demonstrate alternatives: tools such as OpenRing and OpenCircuit can read data from inexpensive rings over Bluetooth and handle it locally, avoiding mandatory accounts or remote servers. Those projects are less polished than commercial apps, but they show the cloud isn’t technically required for basic ring functionality.
Where the category is headed
On one side of the market, companies continue to sell premium rings bundled with subscriptions and broader health ecosystems. On the other, cheaper hardware is proliferating and established brands are expanding downward. Meanwhile, researchers are exploring more advanced sensing: teams at UC San Diego have prototyped rings that analyze sweat for biomarkers like glucose and ketones rather than relying solely on optical signals.
Sekonda’s £80 model lands amid these opposing trends. If inexpensive rings reliably provide the core information most users seek, they could change the balance between smartwatches and finger-worn wearables — but algorithm quality, independent validation and data-handling choices will determine how many buyers feel comfortable making that switch.
