Mira is a device designed to monitor a woman’s activity. A smart-looking cuff, it blends well with any wardrobe choice while its smartphone app keeps the wearer updated on physical activity or even offers feedback. The tracker itself can be detached from the stainless steel band and be clipped to clothes or left inside a pocket. The battery lasts for up to 5 days and can be recharged by using an adapter or plugging it into your computer. Mira retails for $169 and is available in two separate colors (brushed gold and midnight purple).
