The Fitbit Google Ace LTE is a kids' smartwatch that brings several unique features to the table. It comes with built-in cellular 4G LTE and GPS location tracking, which ensures kids are never far from reach.

This watch is also designed to keep kids active with a variety of movement-based games available through the Fitbit Arcade, which encourages physical activity through fun challenges that record steps and movements.

One of its standout features is the Noodle activity ring that celebrates achievements with animations, making it engaging for children. Additionally, the School Time feature helps limit gameplay during school hours to ensure children stay focused, although they can still reach out if necessary.
