- Rogbid has begun selling a hybrid “smart ring watch” called Fusion.
- The device is pitched as a low-cost blend of ring-worn tracking and wrist-worn display.
- Early coverage has focused on its price and its claim to add health sensors to a ring-watch format.
Rogbid has started selling a $49.99 Fusion device that can be worn on a finger or strapped to a wrist, bringing heart-rate and sleep tracking to a ring-watch format. The pricing undercuts ring watches from Casio and Timex that have largely stayed closer to novelty timepieces, The Verge reported.
The launch matters now because the wearables market is looking for new shapes that people will actually keep on, day and night. Rings are part of that push: small enough to forget about, but still able to collect sleep and activity data.
Fusion sits in the middle of two camps. Ring watches give you a screen, but often not much else; smart rings track health, but usually skip displays and lean on the phone app.
Notebookcheck said Fusion uses a 0.49-inch OLED display — a small, bright, low-power screen — and an adjustable Milanese-style metal mesh band, with a strap that can be swapped to wear it like a mini smartwatch. The site said Rogbid is pitching heart-rate and blood oxygen saturation (SpO2) sensors, sleep and cycle tracking (often used for menstrual cycle tracking), and more than 100 sports modes, along with a 5 ATM water-resistance rating — roughly 50 metres — plus a claimed five-day battery life and a one-hour charge. It noted the $49.99 price against health-focused smart rings such as Oura’s Ring 4, which it said starts at $349 on Amazon.
Trend Hunter highlighted the same swap-and-wear setup and said the screen shows step count, time, heart rate, sleep data and blood-oxygen readings. It also said the device is compatible with Android and iOS phones and will be sold in gold, silver and black finishes.
Digital Trends said Rogbid lists Fusion at about 14 grams and 20.6 x 21 x 8.2 mm, and claims it can operate from about -20°C to 60°C. The outlet said the device does not support Bluetooth calling, a feature common on larger smartwatches.
For established watch brands, ring watches have leaned into retro looks and simple functions. For smart ring makers, the pitch has been comfort and passive tracking, with the phone doing the heavy lifting.
But the ultralow price comes with unknowns. Most of the early details rest on Rogbid’s own specifications, and buyers will have to wait for independent testing to show whether the sensor readings and battery claims hold up in daily wear.
Rogbid’s bet is straightforward: make it cheap enough that curious buyers try the form factor. Whether people keep a screen on their finger is a different question.
