There may be several causes for this malfunction. There are also just as many fixes that can be implemented quickly and without any risk to the device. We outline these fixes below. The tips in this article can be used to fix sync problems with all Fitbit tracker models from Fitbit Charge 3 and Fitbit Ace to Fitbit Ionic and Fitbit Versa. Fitbit Cause of Fitbit Sync Errors Fitbit sync errors are usually related to the fitness tracker becoming disassociated with the smartphone, tablet, computer, or iPod touch it was initially connected to. This can be caused by connecting to too many devices at once, the Bluetooth not working properly, or a minor glitch in the Fitbit's operating system. How to Fix a Fitbit Tracker Sync Problem It's difficult to pinpoint exactly why a Fitbit won't sync properly to an iPhone, Android, or another device. However, there are a variety of proven solutions that can fix the problem, and these work with all Fitbit fitness tracker models. Force a manual sync. Sometimes the Fitbit app needs a little prodding to initiate sync even after it's opened. To force a sync, tap the member card icon, tap the name of the Fitbit tracker, and then tap Sync Now. Check the Bluetooth settings. A Fitbit tracker syncs data to smartphones, tablets, and computers using Bluetooth, so it won't be able to connect if Bluetooth is disabled on the device. Bluetooth can be turned on and off from quick menus on most smart devices. On iPadOS, swipe down in the upper-right corner to open this menu. On Android and Windows Phone, swipe down to open it. Install the Fitbit app on your device. If you purchased a new Fitbit tracker, you likely installed the official app on your smartphone, tablet, or computer to set it up. However, if you received a Fitbit second-hand, you may not have. Unlike other devices, a Fitbit requires installing a special app to connect to another device and sync data. Update the Fitbit. The device may have trouble connecting to the tracker if it's outdated. Only sync the Fitbit to one device. It may seem like a good idea to pair your Fitbit tracker with your iPhone while out of the house and your Windows 10 computer for when you're at home, but this can cause a conflict for the tracker when it tries to connect to both at the same time. The best way to fix this is to turn off Bluetooth on one device when trying to sync to the other. You can also turn the second device off completely. Disable Wi-Fi. Sometimes having a smartphone or tablet's Wi-Fi and Bluetooth turned on at the same time can prevent each of these technologies from working properly. If you're trying to sync a Fitbit tracker, this can hinder the Bluetooth connectivity and prevent it from syncing. Check the Fitbit battery. While Fitbit trackers have a long battery life, these devices need recharging every day or so. If a tracker isn't syncing, it may have run out of power and turned off. This is likely if you own a Fitbit One or Fitbit Zip. These are usually placed in a pocket or bag and are easy to forget about when it comes to device charging time at the end of the day. Restart the Fitbit tracker. Restarting a Fitbit is essentially the same as restarting a computer. It refreshes the device's operating system and typically fixes any issues you may experience, such as syncing problems. Instructions for restarting a Fitbit vary from model-to-model but generally involve plugging the tracker into the USB charging cable, connecting it to a power source, and holding the main button for around 10 seconds. If done correctly, the Fitbit logo flashes on the screen, and the device restarts. Restarting a Fitbit won't delete any data besides notifications. A restart is usually required after encountering one of the problems mentioned above, such as Wi-Fi and Bluetooth conflicts or being connected to multiple devices. Reset the Fitbit tracker. Resetting is a last resort, as it deletes all data and returns the Fitbit to its factory settings. You can restore any data synced to your online Fitbit account after the reset. Resetting a Fitbit differs depending on which model you own, with some requiring a paperclip inserted into a hole while others are done in the device's settings. Some trackers, such as the Fitbit Surge and Fitbit Blaze, have no factory reset option. Don't confuse restarting and resetting when talking to online or offline customer support. Restarting a Fitbit turns it off and on again while resetting deletes everything on it.
