The plethora of fitness wearables arriving in India continues with American firm Fitbit being the latest to arrive. After an initial launch on Amazon in June, the full Fitbit product line will be available progressively through September at Reliance Digital, Croma and Helios retail stores across India. Fitbit has brought its entire range of fitness wearables to India. Two of these, the Fitbit Surge and Fitbit Charge HR, are meant for fitness enthusiasts who need to keep track of their heart rate as well as distances covered and calories burned with each workout.Fitbit Charge HR and Surge pair with smartphones via Bluetooth and display notifications. The Fitbit family of trackers also includes Fitbit Flex, Fitbit One, Fitbit Zip and the Aria Wi-Fi Smart Scale which are priced at Rs 6,990, Rs 6,990, Rs 3990 and Rs 9,900 respectively. The company also announced the launch of FitStar Personal Trainer. Acquired by Fitbit earlier this year, FitStar is one of the largest platforms for delivering personalised video-based workouts. The Surge is the most premium model in Fitbit's lineup, and it can be categorised as a fitness watch. It features notifications for phone calls and text messages and lets you control music playback as well. It also combines features like built-in GPS, PurePulse continuous wrist-based heart rate tracking, all day fitness tracking with smartwatch functionality. It includes up to 7 days of battery life. Fitbit Charge Wireless Activity Tracker and Sleep Wristband is a simpler fitness band with a heart rate monitor. It has a tiny OLED screen and just one button on the side. The heart rate sensor and charging port are on the inside of the band, which is comfortable to wear. The watch pairs with your phone via Bluetooth to provide notifications for incoming calls. Unfortunately it doesn't support text notifications or music controls. Fitbit Flex Wireless Activity Tracker and Sleep Wristband offers a slim, minimalistic design for people who are goal-oriented and want more flexibility in accessorizing; tracks steps taken, distance traveled, calories burned, active minutes and sleep.It has 5 days of battery life. Fitbit Zip Activity Tracker is a simple clip-based activity tracker that tracks steps taken, distance traveled and calories burned. It has up to 6 months of battery life. Fitbit One is an advanced clip-based activity and sleep tracker that tracks steps taken, distance traveled, calories burned, floors climbed and sleep.It has 10-14 days battery life. Fitbit Aria Wi-Fi Smart Scale tracks weight, BMI and body fat percentage over time; wirelessly syncs stats with online graphs and mobile tools that provide a long-term overview of progress. If you're a serious fitness enthusiast, we'd recommend buying the Surge even at this steep price. The Charge HR is less useful and offers less value even at its price.
