From here, you'll be able to see a summary of your exercise over the weeks and tapping on each will present more information, including time active within heart-rate zones, a heart-rate graph and calories burned, as well as the impact that activity had on your day in terms of steps taken, calories burned and active minutes. Once an activity is recognised, it will appear within the Track Exercise tile in the Dashboard tab of the Fitbit app. Generally speaking, the Alta HR is good at knowing what exercise is what, but if it gets it wrong, you can choose between numerous options, including those that aren't auto-recognised (such as rowing) from within the app. However, it is possible to individually adjust the length of time you need to be doing each of the recognised exercises before tracking begins, and it's also possible to categorise the exercise in the Fitbit app once you have completed it. The 'Reminders to Move' feature is also present (which does as it says: alerts you to get off your ass), as well as call, text and calendar alerts. The Alta HR also offers Fitbit's SmartTrack feature, which means it will automatically recognise certain activities, such as running, walking and elliptical workouts, recording them in the exercise section of the app. Fitbit has made improvements in its sleep tracking functionality, adding heart-rate tracking to sleep, REM information and breaking sleep down into more useful data. The Fitbit Alta HR tracks steps, distance travelled, calories burned, active minutes, heart rate and sleep data.

We achieved between six and seven days most weeks, which isn't quite as good as the Withings Activité Steel HR and it's 20-something days, but it's still impressive for a device this size. The original device offered a five day battery life, but Fitbit has increased this to seven days for the HR model, which we have generally found to be accurate. The charging port is positioned on the underside of the Alta HR too, offering the same mechanism as the original Alta with a bull-dog-style clip that locks into the pins. All the bands for the Alta are also compatible with the Alta HR. Extra bands include leather options for a smarter look there's even a bangle for when you want to wear the Alta HR out for the night - you'd be surprised how many steps dancing involves. The HR comes in four standard colours, all of which have a textured elastomer band, but there are special edition models available, too. On the underside of the Alta HR are clips that enable you to remove and change the straps easily. There are occasions where you have to tap a little harder, but overall it's a good display - just not an exceptional one in bright conditions. The display is sharp enough in appearance and responsive to touch-based controls most of the time, allowing for easy progress checking without opening the accompanying Fitbit app. Like the original, the Alta HR has a lovely chamfered metal frame with a 1.4-inch OLED display on top.

The HR therefore measures just 15mm wide, making it very unobtrusive compared to its larger siblings. Fitbit has managed to make the PurePulse monitor smaller compared to the Charge 2, Surge and Blaze trackers, which in turn means the Alta HR is the same size as the original Alta.
