 7 Best Fitness Tracker for Teens in 2021

Fitbit Inspire 2: Our Best Pick

Fitbit Inspire 2

Fitbit is famously known for its reliable and accurate fitness trackers. Currently, the Fitbit Inspire 2 is one of the more recent devices to hit the market in 2020 (August, to be exact). It’s an entry-level tracker, meaning it’s is a perfect device for a teen as it’s geared toward those who are at the start of their fitness and health journey. 

Inspire versus Inspire 2

In terms of the differences to the first generation, it’s more evolution than a full remake. For example, it has an improved design and new features to encourage new-to-fitness users to make healthier choices. Unfortunately, there’s no GPS, which can be an additional useful feature for a parent with younger children. 

Design

The Inspire 2 isn’t much different from the Inspire HR, and they both come with either a white, black or rose band. Compared to the predecessor, it’s slimmer, but not significantly. Also, Fitbit removed the physical button on the side of the reasonably small 0.7inch PMOLED touchscreen display.

Activity tracking

Firstly, Inspire 2 was the first in the range to offer Active Minute Zones, a new feature that follows health guidelines for exercise. Meaning, it’ll help you to reach goals each week, get a certain number of steps in or hit given heart rate zones. Although this might be a little too in-depth for your younger children, it might get your older kids interested in how their bodies work. But you do get a year of free Fitbit Premium which opens up a range of activities including instructor-guided ones, which may be useful. What’s more, there are meditation and breathing sessions to help them relax as well as hitting their active targets.

Sensors and features

Additionally, there’s sleep tracking which will give you a sleep score to indicate the quality. As a parent, it’s handy to know if your teens have been staying up until the early hours, which might explain why they’re so lethargic! 

Also, the Inspire 2 lacks a SpO2 sensor, so you can’t track blood oxygen levels. But, the lack of sensors and GPS mean you get a great battery life of up to 10 days, which is great for any Fitbit.

However, if the lack of GPS is a deal-breaker for you, don’t worry and keep reading.

Pros

  • Well-known brand
  • Sleep tracking
  • Free year of Fitbit Premium to encourage teens to get active

Cons

  • No GPS
  • No SP02 sensor

Fitbit Luxe: Best Luxury Fitness Tracker

Fitbit Luxe Black

Fitbit’s new watch is an affordable exercise tracker with smart technology. Fitbit has launched the Fitbit Luxe, a new slimline exercise tracker featuring a stainless steel body, an AMOLED display, and a SpO2 sensor.

Recently photos of the Luxe, the new fitness tracker, leaked online, giving us our first look. In terms of style, it’s similar to last year’s Fitbit Inspire 2, with a similar narrow monitor and straight lines. Unlike the Inspire 2, the Luxe’s case is made of smart stainless steel rather than polymer, lending it a more upscale look, whereas the tracker’s frame is smaller for a more convenient fit.

Historically, fitness trackers and sports watches have become very utilitarian in nature, but we’re seeing an increasing range that are both trendy and functional.

Garmin introduced the slim Garmin Lily earlier this year, and Polar recently launched the Polar Ignite 2, which features both regular silicone bands and Swarovski crystal-encrusted bands.

Fitbit has now followed suit. The standard version of Luxe features a silicone necklace, but a limited edition features a soft gold-coloured connection bracelet from jeweller Gorjana, as well as other metals and woven bands.

Fitness features

The Fitbit Luxe, like the Versa 2, Versa 3, and Sense, will feature an AMOLED display, which can have more battery power than the PMOLED display on the Inspire 2. According to Fitbit, the Luxe would last approximately five days between charges.

In terms of exercise tracking, the Luxe will measure the pulse rate, respiratory rate, and sleep – and, unlike the Inspire 2, it will also have a SpO2 tracker and skin temperature monitoring in a potential app upgrade.

The tracker features over 20 fitness styles and Fitbit’s Smart Track feature, which automatically begins monitoring exercise if you fail to manually trigger it.

The Luxe receives call, text, and smartphone notifications, but lacks an on-board GPS receiver; instead, the Luxe utilises the GPS receiver on your phone to chart runs, hikes, and bike rides. It’s a decent system, but you can’t leave your phone at home during training sessions, in our experience.

The Fitbit Luxe will retail for different prices depending on which version you get. Don’t forget the exclusive edition of the Gorjana connection band in a soft cold colour. This price puts it exactly between the Fitbit Inspire 2 and Versa 3.

It costs marginally less than the Garmin Lily, which has a comparable specification, launched earlier this year.

Pros

  • Gorgeous design
  • Advanced health tracking

Cons

  • Looks similar to existing Fitbit modles

Garmin Lily: Best Smartwatch for Female

Garmin Liliy

The Lily is a smartwatch targeted at women. It has a slim appearance, an appealing face, and a thinner band than any previous Garmin. Sadly, despite promoting the company’s female-focused features, it lacks certain core tools that we’d like to see on a modern watch at this price point.

Features 

Menstrual monitoring is present. More you can send an emergency response to a friend easily by continuously tapping the touchscreen. It’s a shame, though, that the Lily lacks onboard GPS, which has been a feature of Garmin’s range since their conception. There is still no NFC, meaning you can’t use Garmin Pay, which is a big letdown for a watch made for daily use.

The Lily believes you’ll always be with your smartphone, you can use it to control music.

Raising your wrist unlocks the display, but it does not always function as intended. You can change the watch’s motion response, but keep in mind that this will reduce battery life.

Design

The Lily is a women’s smartwatch, but Garmin didn’t just ‘pink it and shrink it.’ It has also produced a whole new look.

The Lily Classic, which has an Italian leather wristband, and the Lily Sport, which has a silicone bracelet similar to those used on smartwatches and fitness trackers, are also available. Both come in three colours (neutrals, soft purples, and black), and the bands can be replaced.

The thickness of the band is one of the most noticeable variation between the Lily and a traditional exercise tracker. It’s much shorter (only 14mm) and narrower (designed for a wrist circumference of 110-175mm). Longer bands are available. And at night, it’s so cosy that you forget you’re wearing it.

The Lily’s exceptionally bright TFT LCD monitor is another standout feature.

The device has a good range of well-designed faces to choose from, but we’d like to see an analogue alternative, particularly because more can’t be downloaded from Garmin Connect IQ.

Sporting watches, such as the Garmin Instinct and Polar Grit pair, are chunky and “manly,” but not the Lily. It is, instead, a feature-light smartwatch. The Apple Watch and Amazfit GTS, for example, are gender-neutral – attractive and modern, with a slender enough profile to fit under a sleeve. So is a gendered smartwatch actually needed?

If Garmin could combine the Lily idea (neat, lightweight, and appealing) with the serious sports-tracking intelligence shown in the Forerunner, it would be even more unique – even if the price would be so much higher.

The Lily has a 5ATM water resistance rating, which means it can be submerged for 10 minutes at depths of up to 50 metres. Meaning this is ideal for pool swimming and showering.

Fitness and health tracking

The Garmin Lily will monitor your deep, light, and REM sleep during the night and provide you with a report about how well you slept. A pulse oximeter measures SpO2 levels when sleeping, is also available. Many similarly priced gadgets only record SpO2 during sleep, so the Lily could be a better option if you use it as a health measure.

There are heart rate warnings (both low and high), and if the watch senses that the heart rate is unusual. If so, it’ll take you through a five-minute breathing exercise to slow it down.

As previously said, one of the Garmin Lily’s main flaws is its lack of onboard GPS. It does, however, have Connected GPS, which uses your phone’s navigation to assist you when you walk, drive, or cycle.

There are only seven sport modes to choose from, which is less than most Garmins but includes all of the popular ones. Riding both indoors and outside, weights, swimming, and cycling are options. This isn’t a device for specialised activities like alpine skiing or hiking, but the limited variety makes sense.

The Lily will save up to 14 days of monitoring data.

Set up an emergency contact in the Garmin Connect app, and if you get into trouble, you can send a message to that person by tapping the watch’s screen repeatedly. Your contact will receive a text message containing your GPS coordinates, which they will then enter into Google Maps to locate you.

There’s also Livetrack, which helps a friend or family member to track your whereabouts. It works well and generates a precise map for your contact to follow on their own phone through Garmin Connect. Simply remember to turn it off when you’re done to prevent exhausting the battery.

All in all, a very female-focused watch!

Pros

  • Great battery life
  • Handy safety features

Cons

  • No NFC
  • Do we need a gender-specific watch?

Fitbit Charge 4: Best Advanced Activity Tracker for Tweens

Fitbit Charge 4

Now, the Fitbit Charge 4 is an older Fitbit but it’s still one of the best fitness trackers for teens. Even better for slightly older teenagers, it has Fitbit Pay, smart notifications and alarms. Plus, it has decent 7-day battery life.

Design

It has a rectangular 1-inch OLD greyscale touchscreen and interchangeable band. If your teen is fashion-conscious, it comes in 4 different colors.

Activity tracking

As for variation, charge 4 will track a multitude of different sports, so you can keep your teen interested through doing different activities. On the whole, it’ll monitor steps, calories and distance. Also, it has a constant heart rate monitor. 

Sensors and features

What’s exciting about the Fitbit Charge 4 is that it has built-in GPS, which helps you to navigate outdoor activities. As we said, GPS is also a nifty bonus for concerned parents who want to keep an eye on their kids and teens to ensure their safety. More, it’s perfect for those outdoor adventure-type families who enjoy hikes, running and cycling.

Now, it won’t provide a wealth of in-depth data like a Polar, Suunto or Garmin, but if you’re buying this for a teen, you won’t need it. What’s also cool is that this model has an altimeter, so your teen will know how many levels of stairs they’ve climbed.

Especially handy is the fact this tracker is water-resistant to 50m. Meaning it’s OK in the shower, rain and will not be affected by sweat. Particularly durable watches are naturally going to be great for teens.

Finally, it comes with Fitbit Pay and music control for Spotify, making it a great smartwatch as well as one of the best fitness trackers for teens.

Pros

  • GPS onboard
  • Music control
  • Water-resistant

Cons

  • Activity data isn’t very in-depth

Mi Band 6: Latest Mi Smart Band

Xiaomi Mi Band 6

The Xiaomi Mi Smart Band 6 looks unremarkable at first sight but comes loaded with apps for health and fitness.

Its architecture is similar to last year’s Xiaomi Mi Smart Band 5, with the notable exception of the display, which is brighter and sharper, making it easier to view your everyday stats at a glance.

  • Track all-day activity: your steps, distance,...

On the features front, you have the option of all-day stress monitoring as well as getting a pulse ox tracker and breathing data.

The app tracks your heart rate very accurately, giving you the ability to fine-tune your fitness settings.

However, there are several drawbacks. The tracking turned out to be somewhat unreliable, but this isn’t a shock for a budget tracker. You should also keep the band sufficiently tight to avoid friction when long-distance running.

We see these as minor details, and if you want anything with more than basic step-tracking, we suggest the Mi Smart Band 6.

Design and features

  • Quite similar to Mi Smart Band 5
  • Brilliant display
  • Waterproof up to 50m

It’s a mid-range exercise tracker with a small, long, plastic wristband, almost identical to its predecessor.

The display is very readable at a resolution of 152 x 86 pixels. There are various options so you can choose your favourite face and access your complications with one tap.

It’s water-resistant to 50m but it’s best not to take this watch diving or snorkelling. Light showers at best.

The Xiaomi Smart Band 6 has several more features that are associated with a pricier wearable. This includes stress tracking breathing exercises and female cycle tracking.

There is no onboard storage for music on the Mi Smart Band 6. You will be getting text and phone notifications on your wrist but sadly you can’t make calls. Also, there is no Alexa or Google Assistant because there’s no microphone.

The Mi Smart Band 6 records REM sleep cycles, measuring deep and light sleep accurately.

Xiaomi claims a 14-day battery life, but using any of the above a lot can reduce this down significantly. 

Fitness tracking

There is GPS present, but some users have experienced some inaccuracies. Again, not too much of a shock with a budget tracker.

It has auto-pause which pauses the tracker after just a few seconds of inactivity. You 

won’t lose track of your workout, say while you’re waiting at a crosswalk or while running.

Your total cardiovascular (heart and lung) health score, known as PAI, is given. Regardless of the numeric value, you can see an increase in your physical health as you progress in your fitness journey.

If you’re just starting and only want some basic or rough data, the Mi Smart Band 6 might be an effective training tool for you.

Pros

  • A lot of features for the price
  • Affordable
  • Cardio score is useful

Cons

  • Data isn’t entirely accurate

Mi Smart Band 5: Cheap Activity Tracker for Teens

Mi Smart Band 5

Another one of the best fitness trackers for teens is the Mi Smart Band 5 from Xiaomi. In fact, they’ve really excelled themselves in this upgrade from the Band 4. 

Design

Firstly, it has a clear and bright display which is easily seen in various lighting conditions. The design is undeniably sporty.

You don’t get any physical buttons and you navigate the display (a 1.1-inch AMOLED display offering 126 x 294 resolution) by scrolling.

Notably, it can be worn safely in the rain or a shower, which is handy for the forgetful teens out there. 

Activity Tracking

Secondly, there’s a decent HRM on board with a step counter and the ability to track different sports. Similarly, to the Inspire 2, there’s no built-in GPS, but you can sync it to your phone, which, as a parent, you may want to do anyway.

More, this then offers simple data and the ability to easily record activity; perfect for teens and even tweens.

Smart features

It’s compatible with both Android and iOS. If your teen has their own phone, they can connect it up for smart notifications, which they’ll love. Additionally, they can also control their music which is a huge encouragement for exercise!

Second to last is the battery life. Your teen can get up to 14 days between charges, which is one of the best on the market for a budget fitness tracker.

Pros

  • Water-resistant
  • Excellent battery life – 14 days

Cons

  • No built-in GPS

Letscom Fitness Tracker: Cheap Fitness Tracker under $25

Image of Letscom Fitness Tracker Blue color

The Letscom Fitness tracker is another budget device, coming in at under $50. Making it a superb choice for any teen who is yet to appreciate how much things cost and are slightly haphazard. 

Design

This device has a 0.96-inch HD display with brightness control. Also, it comes in plenty of colors like green, pink, blue, purple and black. Whilst it looks similar to the Lintelek, the colors are more pastel-based.

Activity and fitness tracking

During exercise, your teen can see their heart rate at a glance. When they’re done, they can see what their heart did during the workout in the app that details maximum/average and resting heart rate.

This can be assessed using any of the 14 exercise modes built-in, such as running, hiking or biking. And, what’s really exceptional about this sub-$50 device is that it has built-in GPS to see the distance travelled during these sessions on a post-workout map.

All in all, it’ll keep an eye on calories, steps and distance during the day with a handy vibration reminder if your teen hasn’t moved around in a while.

For peace of mind that your teen is getting enough good quality sleep, this device will tell you about their time spent awake and in light and deep sleep stages.

Smart features

If your teen has a smartphone, they can connect it and get their call, text, email and social media notifications on their wrist.

You get all this with a fantastic 7-day battery life that only takes 2 hours to reach a full charge.

Pros

  • Built-in GPS
  • Fitness tracking and smart features in one device
  • Fast charging

Cons

  • Battery life isn’t as long as others on this list

Conclusion

The best fitness trackers for teens depends on what features you’re looking for. If you want something that will last them a long while, get something made of silicone with a waterproof rating like the Garmin Vivosmart 4. 

However, if you want to actively encourage your teen to get up and move about then we recommend you opt for a Fitbit tracker that comes with a free one-year subscription to Fitbit Premium, where you can utilize all the features and guided workouts so your teen doesn’t have to go it alone or without any knowledge of where to start.

Perhaps GPS is an important feature, in which case, again, the Charge 4 is your best option.

Finally, if you’re after something that is a compromise between a fitness tracker and a smartphone because they struggle to put theirs down, we recommend the Lintelek or Letscom, which does a decent job of both functions at a minimal cost.
