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.

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).

Handedness

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.

Troubleshooting

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
