The most important news for Samsung fans: the new accessory for the finger will be launched this year. The Korean manufacturer confirmed this at the MWC in Barcelona. "Later this year" is the official wording.

And while the smart ring was only shown to a few members of the media when it was announced at the CES tech fair in Las Vegas in January, it can now be seen by everyone at the Mobile World Congress. So I can see it for myself. However, the ring is locked in glass boxes - touching it is prohibited.

The ring in three colours is an eye-catcher at the trade fair

Three colours are on display at the MWC: black, gold and silver. Each in just under a dozen different sizes from 5 to 13, which is of course crucial for a good fit with rings.

I can't see any of the technology from the outside, but the sensors and charging contacts are visible on the inside. The design of the ring is simple and unobtrusive. I was impressed by the fact that the ring is barely bigger than a normal finger ring. It should therefore be very comfortable to wear.

A health tracker for the finger

What else is known about the ring? It is primarily intended as a fitness tracker that uses sensors to measure your pulse and record health data. This as a supplement to the smartwatch or even as a replacement for all those who prefer to wear a conventional watch or none at all.

The data is collected and analysed in the Samsung Health app. The app gives users feedback by means of a health score. It also provides specific tips and advice to help you move more or sleep better.

The exact sensors are still unknown: A pulse sensor is recognisable in the prototypes on display, and a temperature sensor and an acceleration sensor are also likely to be installed. Unfortunately, NFC for digital payments is rather unlikely; the focus should be strictly on health tracking.

Samsung has also revealed to South Korean media that the battery life should be up to nine days. Other sources speak of five to nine days before the ring needs to be recharged.

There are still many unanswered questions about the technology. The price is also likely to play a major role in whether the Samsung ring really heralds a new era of wearables. Rumours suggest a price of around 300 euros or francs. That would also be an affordable investment for the masses. I also hope that at least some of the health and tracking information can be used without a plan.
