Although, as a male, I don't frequently encounter the issue of missing an important call because my phone is lost inside my handbag or purse, I do know that this is an issue affecting a large portion of the female population. To combat this, start-up Ringly has developed a nifty smart ring that offers customizable Bluetooth notifications, flashing different color LED lights and vibration patterns dependent on the nature of the alert. Not only is it highly functional, but it's a very stylish, inconspicuous gadget, and with a flexible, color-coded notification system, it looks a very well thought-out product.
