Get started

Make healthy a habit with Fitbit Inspire 2, the easy-to-use fitness tracker with 24/7 heart rate, Active Zone Minutes, activity and sleep tracking, up to 10 days of battery, and more.
Take a moment to review our complete safety information at http://fitbit.com/safety.
Inspire 2 is not intended to provide medical or scientific data.

What’s in the box

Your Inspire 2 box includes:

Tracker with small band (color and material vary)

Charging cable

Additional large band (color and material vary)

The detachable bands on Inspire 2 come in a variety of colors and materials, sold separately.

Set up Inspire 2

For the best experience, use the Fitbit app for iPhones and iPads or Android phones.

To create a Fitbit account, you’re prompted to enter your birthdate, height, weight, and sex to calculate your stride length and to estimate distance, basal metabolic rate, and calorie burn. After you set up your account, your first name, last initial, and profile picture are visible to all other Fitbit users. You have the option to share other information, but most of the information you provide to create an account is private by default.

Charge your tracker

A fully-charged Inspire 2 has a battery life of 10 days. Battery life and charge cycles vary with use and other factors; actual results will vary.

To charge Inspire 2: 

  1. Plug the charging cable into the USB port on your computer, a UL-certified USB wall charger, or another low-energy charging device.
  2. Align the pins on the other end of the charging cable with the gold contacts on the back of Inspire 2. Gently press Inspire 2 into the charger until it snaps into place.

To remove Inspire 2 from the charging cable:

  1. Hold Inspire 2 and slide your thumb nail between the charger and the back of the tracker on one of the corners.
  2. Gently press down on the charger until it separates from the tracker.

Charging fully takes about 1-2 hours. While the tracker charges, you can press the buttons to check the battery level. A fully-charged tracker shows a solid battery icon with a smile.

Set up with your phone or tablet

Set up Inspire 2 with the Fitbit app. The Fitbit app is compatible with most popular phones and tablets. See fitbit.com/devices to check if your phone or tablet is compatible.

To get started: 

  1. Download the Fitbit app:

Wear Inspire 2

Choose to wear Inspire 2 around your wrist or in the clip accessory (sold separately). If you need to remove the band or attach a different band, see the instructions in “Change the band” .

When you wear Inspire 2 in the band, make sure your tracker is set to On Wrist .
When you wear Inspire 2 in the accessory clip, make sure it’s set to On Clip . For more information, see “Navigate Inspire 2”.

Placement for all-day wear vs. exercise

When you’re not exercising, wear Inspire 2 a finger’s width above your wrist bone.
In general, it’s always important to give your wrist a break on a regular basis by removing your tracker for around an hour after extended wear. We recommend removing your tracker while you shower. Although you can shower while wearing your tracker, not doing so reduces the potential for exposure to soaps, shampoos, and conditioners, which can cause long-term damage to your tracker and may cause skin irritation.
For optimized heart-rate tracking while exercising:

  • During a workout, experiment with wearing your tracker a bit higher on your wrist for an improved fit. Many exercises, such as bike riding or weight lifting, cause you to bend your wrist frequently, which could interfere with the heartrate signal if the tracker is lower on your wrist.
  • Wear your tracker on top of your wrist, and make sure the back of the device is in contact with your skin.
  • Consider tightening your band before a workout and loosening it when you’re done. The band should be snug but not constricting (a tight band restricts blood flow, potentially affecting the heart-rate signal).


For greater accuracy, you must specify whether you wear Inspire 2 on your dominant or non-dominant hand. Your dominant hand is the one you use for writing and eating. To start, the Wrist setting is set to non-dominant. If you wear Inspire 2 on your dominant hand, change the Wrist setting in the Fitbit app:

From the Today tab in the Fitbit app, tap your profile picture > Inspire 2 tile > Wrist > Dominant.

Wear Inspire 2 in a clip

Wear Inspire 2 clipped to your clothing. Remove the bands, and place your tracker in the clip. For more information, see “Change the band”.

To put Inspire 2 in the clip:

  1. If you previously wore Inspire 2 on your wrist, change your device setting to On Clip . For more information, see “Navigate Inspire 2” .
    Note: Make sure Inspire 2 is set to On Wrist  when you wear your tracker in the band.
  2. Hold the tracker with the screen facing you. Make sure the time isn’t upside down.
  3. Hold the clip accessory with the opening facing you and the clip on the back facing down.
  4. Place the top of the tracker into the clip opening and move the bottom of the tracker into place. Inspire 2 is secure when all edges of the clip lie flat against the tracker.

Note that when Inspire 2 is set to On Clip , certain features are turned off, including heart-rate tracking, automatic exercise tracking, Active Zone Minutes, and
Water Lock .

Clip Placement

Wear Inspire 2 on or close to your body with the screen facing outward. Secure the clip tightly to a shirt pocket, bra, pants pocket, belt, or waistband. Try out a few different locations to see what’s most comfortable and secure for you.
If you experience skin irritation when wearing Inspire 2 on your bra or waistband, clip it to an external piece of clothing instead, such as your belt or pocket.

Wear and care tips

  • Clean your band and wrist regularly with a soap-free cleanser.
  • If your tracker gets wet, remove and dry it completely after your activity.
  • Take your tracker off from time to time.
  • If you notice skin irritation, remove your tracker and contact customer support. For more information, see fitbit.com/productcare.

Change the band

Inspire 2 comes with a small band attached and an additional large, bottom band in the box. Both the top and bottom bands can be swapped with accessory bands, sold separately on fitbit.com. For band measurements, see “Band size”.
Most bands for Inspire and Inspire HR don’t fit Inspire 2. Check fitbit.com for certain bands that are compatible with the Inspire series. The Inspire clip accessory isn’t compatible with Inspire 2.

Remove a band

  1. Turn over Inspire 2 and find the quick-release lever.
  2. While pressing the quick-release lever inward, gently pull the band away from the tracker to release it.
  3. Repeat on the other side.

Attach a band

  1. To attach a band, hold the band and slide the pin (the side opposite the quickrelease lever) into the notch on the tracker.
  2. While pressing the quick-release lever inward, slide the other end of the band into place.
  3. When both ends of the pin are inserted, release the quick-release lever.

Check your heart rate

Inspire 2 personalizes your heart-rate zones using your heart rate reserve, which is the difference between your maximum heart rate and your resting heart rate. To help you target the training intensity of your choice, check your heart rate and heart-rate zone on your tracker during exercise. Inspire 2 notifies you when you enter a heart-rate zone.

Icon: Zone: Calculation: Description

: Below Zone: Below 40% of your heart rate reserve: Below the fat burn zone, your heart beats at a slower pace.

: Fat Burn Zone: Between 40% and 59% of your heart rate reserve: In the fat burn zone, you’re likely in a moderate activity such as a brisk walk. Your heart rate and breathing might be elevated, but you can still carry on a conversation. 

: Cardio Zone: Between 60% and 84% of your heart rate reserve: In the cardio zone, you’re likely doing a vigorous activity such as running or spinning. 

: Peak Zone: Greater than 85% of your heart rate reserve:
In the peak zone, you’re likely doing a short, intense activity that improves performance and speed, such as sprinting or high-intensity interval training.

Custom heart-rate zones

Instead of using these heart-rate zones, you can create a custom zone in the Fitbit app to target a specific heart-rate range.

Earn Active Zone Minutes

Earn Active Zone Minutes for time spent in the fat burn, cardio, or peak heart rate zones. To help you maximize your time, you earn 2 Active Zone Minutes for each minute you’re in the cardio or peak zones.

1 minute in the fat burn zone = 1 Active Zone Minute
1 minute in the cardio or peak zones = 2 Active Zone Minutes

There are 2 ways Inspire 2 notifies you about Active Zone Minutes:

  • A few moments after you enter a different heart-rate zone in the Exercise app , so that you know how hard you’re working. The number of times your device vibrates indicates which zone you’re in:

Light buzz = below zone
1 buzz = fat burn zone
2 buzzes = cardio zone
3 buzzes = peak zone

  • 7 minutes after you enter a heart-rate zone throughout the day (for example, during a brisk walk)

Share your activity

After you complete a workout, open the Fitbit app to share your stats with friends and family.

View your cardio fitness score

View your overall cardiovascular fitness in the Fitbit app. See your cardio fitness score and cardio fitness level, which shows how you compare to your peers.

When an update is available, a notification appears in the Fitbit app. After you start the update, follow the progress bars on Inspire 2 and in the Fitbit app until the update is complete. Keep your tracker and phone close to each other during the update.

To update Inspire 2, your tracker’s battery must be at least 40% charged. Updating Inspire 2 may be demanding on the battery. We recommend plugging your tracker into the charger before starting an update.

Restart Inspire 2

If you can’t sync Inspire 2 or you have trouble with tracking your stats or receiving notifications, restart your tracker from your wrist:

Open the Settings app and tap Reboot Device.

If Inspire 2 is unresponsive:

  1. Connect Inspire 2 to the charging cable. For instructions, see “Charge your tracker “.
  2. Press and hold the buttons on your tracker for 5 seconds. Release the buttons. When you see a smiley face and Inspire 2 vibrates, the tracker restarted.

Restarting your tracker reboots the device but doesn’t delete any data.

Erase Inspire 2

If you want to give Inspire 2 to another person or wish to return it, first clear your personal data:

  1. On Inspire 2, open the Settings app > Clear User Data.
  2. When prompted, press the screen for 3 seconds, then release. When Inspire 2 vibrates and you see the clock screen, your data is erased.


If Inspire 2 isn’t working properly, see our troubleshooting steps below. Visit help.fitbit.com for more information.

Heart-rate signal missing

Inspire 2 continuously tracks your heart rate while you’re exercising and throughout the day. If the heart-rate sensor on your tracker has difficulty detecting a signal, dashed lines appear.

If your tracker doesn’t detect a heart-rate signal, first make sure heart-rate tracking is turned on in the Settings app on your tracker. Next, make sure you’re wearing your tracker correctly, either by moving it higher or lower on your wrist or by tightening or loosening the band. Inspire 2 should be in contact with your skin.
After holding your arm still and straight for a short time, you should see your heart rate again.

GPS signal missing

Environmental factors, including tall buildings, dense forest, steep hills, and thick cloud cover, can interfere with your phone’s ability to connect to GPS satellites. If your phone is searching for a GPS signal during an exercise, connecting appears at the top of the screen.
For best results, wait for your phone to find the signal before you start your workout.

Other issues

If you experience any of the following issues, restart your tracker:

  • Won’t sync
  • Won’t respond to taps, swipes, or button press
  • Won’t track steps or other data
  • Won’t show notifications

Safety Statement

This equipment has been tested to comply with safety certification in accordance with the specifications of EN Standard: EN60950-1:2006 + A11:2009 + A1:2010 + A12:2011 + A2:2013 & EN62368-1:2014 + A11:2017.


Can all the sounds be turned off? i do not need to be annoyed by my watch, i have coworkers for that!

your coworkers have nothing to do with this watch. Yes you can turn it off.

This product is available for the same price through Fitbit. Other than faster delivery, any advantages of buying through Amazon?

Faster delivery, offered warranty 3yr for $8 vs 2yr for $20 with fitbit.

Is it compatible with apple phone?

Yes, it is compatible with iPhone. With regards to the vibrations that Waystation49 were referencing, they may be turned off. You may set up a silent alarm which is a vibration as well as a sedentary alert which reminds you when you have been sitting too long and to get up and move which may be disabled. The “strobe light”they were referring to is the heart rate sensor which you will not see unless you are changing the bands or take the Fitbit off because the green sensor is on the bottom which rests against your wrist. If you do not wish to have your heart rate monitored, you may also disable this function. You do not have to have a subscription for the Fitbit to work. You will need to download the Fitbit app to monitor your activity. Fitbit will give you a free one year trial subscription of their Premium Fitbit app accordingly to the product description and after that you will be charged for if you keep Premium.

do you have to pair it to a phone?

No you don’t have to but you miss out on function if you don’t. And if you wanna change the clock face you have to do that on the app which you need to download on your phone. You can view reports on your phone. You can get detailed sleep data on your phone. It’s just better if you sync with your phone.

Is this compatible with an iPad? I’m looking to purchase this for someone who doesn’t own a smartphone, but has an Ipad.


Will the alta hr bands fit this watch?


Foes the watch face show in the sun?

No you really can’t see it in the sun.

How does inspire 2 compare to the first version. Other than the one year added bling? Is it worth upgrading?

There are 2 “original inspire”… the true original and the inspire hr… as noted by the hr… the inspire hr does track heart rate… whereas the TRUE original does not track it.

is the inspire 2 similar in width to the Alta ?

Its a very slim device and is easier to wear than the large smart watch.

Do you need wifi or anything for it to work ? Such as networks?

No. If you want to sync with your smartphone you would need Bluetooth capability. Otherwise it can stand alone.

Does it track hydration?

It tracks how much you drink

Does it measure hydration levels?

No, the watch does not measure hydration levels on its own but the app does let you capture the amount of water you drink each day with quick +8, +16, or +24oz buttons and it will highlight when you are under your target on both the watch and app.

Does this monitor stress levels?

Not exactly plus you need to spend $9.99 per month for all those services after a year.

Do i have to purchase anything after ine year?

you will have to pay for premium, if you get a one year free offer.

Can you change the display to horizontal?

There are multiple face settings you can chose so check them out !
