Many of us use our smartphone to listen to music while working out. The TomTom Spark GPS Fitness Watch could also help you track your workouts. It tracks your steps, active minutes, distance, calories burned, and sleep. The built-in heart rate monitor measures your heart rate without a chest strap. The watch can track running, cycling, swimming, and other indoor and outdoor sports.
TomTom Spark is compatible with popular platforms such as MySports, RunKeeper, or Nike+. The device has 3 GB of storage space for music. It is water resistant up to 40m. Smartphone notifications will be supported with an update later this year. TomTom Spark Cardio +Music will be available for 249 euros in September.[Source]
