Like some Nokia Lumia handsets, the SmartRing features wireless charging. To juice it up, just place it on its charging station.
At first, it will only work with iOS and Android devices, and will support calls, text messages, emails, and calendar notifications. Mota is also working with Facebook and Twitter, and says it will extend to more apps if it gets the support.
The SmartRing is available in black or white, and can be yours for a pledge of $75 (£49, including shipping to the UK). The device will start shipping in March next year.
