See Your Data In The Fitbit App; Wear Ionic; Placement For All-Day Wear Vs. Exercise - Fitbit Zip Ionic User Manual

Ionic can connect to open, WEP, WPA personal, and WPA2 personal Wi-Fi
networks. Your watch won't connect to 5GHz, WPA enterprise, or public Wi-Fi
networks that require more than a password to connect⁠ — for example, logins,
subscriptions, or profiles. If you see fields for a username or domain when
connecting to the Wi-Fi network on a computer, the network isn't supported.
For best results, connect Ionic to your home Wi-Fi network. Make sure you know
the network password before connecting.
For more information, see help.fitbit.com.

See your data in the Fitbit app

Sync Ionic to transfer your data to the Fitbit app, where you can view your activity
and sleep data, log food and water, participate in challenges, and more. For best
results, keep all-day sync turned on, so that Ionic syncs periodically with the app.

Wear Ionic

Place Ionic around your wrist. If you need to attach a different size wristband, or if
you purchased another wristband, see the instructions in "Change the wristband"
on page 13.

Placement for all-day wear vs. exercise

When you're not exercising, wear Ionic a finger's width above your wristbone.
