The Fitbit that fixed my broken sleep schedule is down to £59.99 in Prime Day sale — why I'd buy it over the screen-free Air

(Image credit: Future) Tracking my sleep has been a game-changer for helping me stick to a regular sleep routine, and the sleep tracker I swear by has plunged in price in a new Amazon Prime Day deal. The Fitbit Inspire 3, now £59.99 (was £84.99) at Amazon, comes with 6 months free Premium membership which includes additional features, including a daily readiness score.While it's the Fitbit Air that ranks highly among the best sleep trackers we've tested, the Inspire 3 is an excellent alternative that I, personally, prefer (I'll dig into why below). Plus, it's the Inspire 3 that has been slashed in price today's Amazon Prime Day sleep deals. The Inspire 3 boasts an ultra bright screen display, long battery life (10 days per full charge) and reliable sleep and activity tracking. £59.99 doesn't quite match the lowest price we've recorded on this model (that was £49.99 earlier this year), but it's a standout saving in today's sale. Let's take a closer look...Why the Inspire 3 is the Fitbit I'd buy this Prime DayI've been wearing Fitbit activity trackers for years and the Inspire 3 is the wearable I swear by for reliable sleep tracking. While my bed and sleep times used to be erratic, I know that a consistent bed and wake time, like the 7:1 sleep rule, can help improve your longevity.Wearing the Fitbit, with its comfortable, low-profile design and detailed tracking, has helped hold a mirror up to my chaotic routine. The result? I'm going to bed and waking up at roughly the same time every day.While it's easy to see the appeal of the newer, screen-free Fitbit Air, I personally prefer having a watch face I can glance at throughout the day for a quick look at my sleep and health stats. (Image credit: Future)The Inspire 3 has a slightly higher profile than the Air, but it's still incredibly comfortable to wear to bed. And, taking into account today's 29% off deal, it's a more affordable option. (The Fitbit Air isn't on sale and also has an RRP of £84.99.)The Inspire 3 is laced with sensors that track heart rate, blood oxygen saturation, movement and temperature, which gives you a well-rounded view of your health. The watch face gives you an overview of your stats, but the Google Health app provides a more detailed look at your metrics. (Image credit: Future)In terms of its sleep tracking, I like to spend a bit of time each morning checking out how long I spent in each sleep stage, how long it took me to fall asleep and how often I woke up at night. All of this builds towards your overall nightly sleep score. I then crosscheck these metrics against the healthy ranges provided in the Google Health app. This deal includes six months free access to Fitbit Premium, which offers subscribers guided programs to improve your sleep and stick to a regular sleep schedule, as well as a daily readiness score. After the trial period this will cost a monthly fee of £7.99.Want the latest model and don't mind paying full price?
