Within the app, you can also determine which smartphone notifications you’d like to buzz on your wrist. (You can also opt in to the app’s Premium version, which usually costs $10 per month.) The Charge 5 has 21 activity modes, six of which you can add to your on-device favorites list via the app. (Orienting yourself with all of its features, however, might take a beat.) Fitbit’s concise, straightforward app lets you parse daily activity data with ease and allows for linking to a robust network of other Fitbit users-which might help keep you motivated. The color touchscreen display is vivid and clear, even in bright sunlight, with easily identifiable icons allowing for unfussy menu negotiation. It reliably detects, nearly always correctly identifies, and automatically begins to record workouts-running, walking, biking, swimming-after about 10 minutes of activity. The Fitbit Charge 5 is among the most accurate for measuring steps and heart rate (although accuracy isn’t everything).
