Fitbit Inspire 3 Activity Tracker with 6-months Premium Membership Included, up to 10 days battery life and Daily Readiness Score

Product Information

The design of the Fitbit Inspire 3 isn’t much different from the Inspire 2, with a slightly wider and longer main unit and a similarly shaped, although slightly redesigned, silicone band. It retains the sleek and light look and feel of its predecessor, and like that device it’s very comfortable on the wrist, and easy to use for most activities. The silicone grips your skin to just the right degree to avoid uncomfortable movements while exercising, although it might pull a few hairs if you fasten it quite tight – which is recommended for the most accurate heart rate readings. The Inspire 3’s heart rate monitoring 24/7 proved reasonably accurate in our testing, and this data feeds into lots of other features of the device, such as calorie count and exercise zones (cardio and fat-burning, for example). In April 2022 Fitbit added irregular heart rhythm notifications to the Inspire 2, and the Inspire 3 also has this potentially life-saving feature. The Premium subscription gets you some extra features, including a Daily Readiness Score, a Sleep Profile, and lots of workouts to access through the Fitbit app. There’s no appreciable difference in the battery life of the Inspire 3 compared to its predecessor, despite the addition of the always-on display mode, which in theory should consume more battery life.

In auto-wake mode the Fitbit doesn’t have any problem going even longer than 10 days. The auto-wake mode isn’t very accurate though – it’s technically supposed to activate the screen when you bring your wrist up to your eye line, but we found that we often had to manually wake the device. Health Metrics only available in select countries. Not intended for medical purposes or to diagnose or treat any medical condition. This feature is only intended to provide information to assist you with managing your well-being. The Fitbit Versa 4 offers all the same features as the Versa 3, but it has a refreshed design, whilst also offering Google Maps and Google Wallet support.

During a one-mile walk, the Inspire HR logged 2,479 steps, while a 3DTriMax pedometer logged 2,537, for a difference of only 58 steps. Results for a one-mile run were just as close. The Inspire logged 1,729 steps to the pedometer's 1,768, for a difference of just 39. We've yet to test out this feature, but we hope to update our review with a full verdict on its swim capabilities at a later date.

Thankfully, Fitbit has phased out the tap screen (as seen on the Alta and the Charge 2). The display on the Inspire HR is completely sensitive to touch, so you can swipe up to see your metrics and down for access to different apps. Swiping across the display feels responsive and swift, even when sweaty at the gym. Fitbit might not have revolutionized this device from a smart features point of view, but the new design and color display bring real improvements to the user experience. The main unit is slightly wider than the Inspire 2, but that makes no difference to its lightweight nature - the Inspire 2 weighs 8g while Inspire 3 is 17g, which is still ridiculously light. Some will probably still find that it’s a little small for scrolling through the various options or reading post-exercise data, although you can of course also see your data in the Fitbit app on your phone, where everything is laid out clearly and intuitively. We tested the battery life of the Fitbit Inspire 3 in both the always-on display and auto-wake mode. We’re impressed that Fitbit has managed to keep the battery life the same as previous models, at around 10 day, even when in always-on mode. It’s possible that Fitbit has implemented battery optimizations elsewhere to compensate for the effect of the always-on display. As on the Inspire 2, two haptic buttons on each side of the main unit can be used to wake the device and bring up the home screen with the time. This is very handy, because unless you have the ‘auto wake’ option turned on the Fitbit’s display won’t wake automatically when you raise your wrist (to avoid interrupting your sleep during the night with its high brightness).

Fitbit Inspire 3

The Fitbit Sense has the same design as the Versa 3 and the same features, but it offers extra sensors, including with an EDA sensor for monitoring stress, the ability to take an ECG and a skin temperature sensor. The Fitbit Versa 3 is an upgrade to the Versa 2, adding Google Assistant as an option on top of Alexa, a built-in speaker for taking calls, Pure Pulse 2.0 heart rate technology and most importantly, built-in GPS. I think this is a clever way to look at sleep, as it helps you focus more on how you can maximize your sleep quality in the hours of sleep you’re getting, rather than simply trying to go to bed earlier when you’re not tired in a bid to hit that magic eight-hour number, and then becoming stressed when you can’t sleep.

During your workouts, the Inspire HR also identifies heart rate zones depending on your beats per minute. On its display, you can see whether you're in fat burn, cardio, or peak zone, which then allows you to adjust your workout accordingly. Conclusions The Fitbit Charge 4 nylon strap is extremely comfortable to wear. The woven nylon is very soft and light, and is feels comfortable on the wrist. Because of this you can wear this wristband in every occasion, it is very suitable for daily use. Thanks to its fine Velcro fastener, you can easily adjust the bracelet to fit your wrist comfortably. Stainless steel wristbandsAs someone who struggles with sleep anxiety, I found the data especially useful, and a reassuring counter to the orthodoxy that anything less than eight hours sleep isn’t enough. For example, my sleep times during my testing period were always around six hours a night, which conventional wisdom would suggest is not enough. However, my average Sleep Score in the Fitbit app was always around 70/100, and tagged as ‘Fair’.

While Fitbit has built on the impressive Inspire 2 with the addition of a color display, and a minor redesign, it hasn’t added much in the way of features, which is a bit of a shame. However, given that the Inspire 2 was already a very capable device, it’s perhaps a case of evolution rather than revolution.
