There are plenty of interesting smartwatches available on the market. Not everyone is ready to replace their existing watch with an Apple Watch though. Trivoly is a small disc that attaches to your existing watch and makes it smarter. It offers smart notifications, fitness tracking, and smartphone control.
Trivoly lets you interact with your favorite apps (music, camera, …). It is super thin and does not get in your way. The device is compatible with iOS and Android devices. Trivoly is water resistant and has a 4-day battery life. It offers vibrating alarms as well. The product is expected to ship in February 2016.[Source]
