Updating your Fitbit Alta HR
Free feature enhancements and product improvements are occasionally made available through firmware
updates. We recommend keeping your Alta HR up to date.
You’ll be notified in the Fitbit app when an update is available. After you start the update, you’ll see a
progress bar on your tracker and in the Fitbit app until the process is complete, followed by a
confirmation message.
Note that updating your Alta HR takes several minutes and may be demanding on the battery. For this
reason, we recommend plugging your tracker into the charging cable before updating.
