Suunto knows that useful doesn’t have to look utilitarian. The new 3 series uses the GPS you’re already carrying (your phone) to tell you more about how you train. GPS data gives you access to your distance covered, speed metrics and more. The free Suunto app lets your smartphone communicate with your watch, and it provides access to more than just a GPS signal – it sends notifications, reminders and messages right to your watch. As it learns your current activity level, the 3 Fitness provides you with a personalized training plan and live updates to let you know when to go harder or slow down. It adapts if you miss a workout, or you crush it harder than you have before. If a training plan isn’t your style, the 3 series is preloaded with 70 different activity profiles. When not training, the activity tracker keeps track of your steps and calories, and monitors the quality of your sleep. It then takes all of your data into consideration when calculating recovery times and progress.
