Overview
The Fitbit Ace LTE (June 2024) is Google's kids watch: calls, messages and live location for parents, wrapped around motion-based games that turn physical activity into in-game progress. Connectivity runs on Google's own Ace Pass subscription, which is US-only.
What it does well
- Games that reward movement. Titles like Noodle and Bit Valley convert real activity into game progress, a genuinely different approach to kids' fitness motivation.
- A controlled contact circle. Calls and messages work with up to 20 approved contacts, plus live location through Google.
- Tap to Pay for kids. Works with Greenlight and GoHenry kids' debit cards (US), so a child can pay without carrying a card.
- Designed for shallow water: Google says the Ace LTE can withstand rain, shallow pools and sweat, but not extended submersion, high-velocity water or high-temperature water.
Tradeoffs to know
- The plan is the gatekeeper. Calls, messages and location require the Ace Pass subscription, available in the US only; outside the US the watch loses its core features.
- Battery is listed at roughly 16 hours: plan on daily charging.
- Third-party app support has not been verified for this model; it is a kid-focused system.
Price and availability
$229.95 official launch price, plus the Ace Pass subscription for connected features. Factor the subscription into the total cost.
FAQ
Does the Fitbit Ace LTE work outside the US?
The Ace Pass plan that powers calls, messages and location is US-only. Check coverage before buying from abroad.
Does it need a phone?
The watch has built-in LTE (SIM included), so the child does not need a phone; parents manage it from the Fitbit Ace app on iPhone or Android.
Can my child swim with it?
Google says the Ace LTE can withstand shallow pools, but should not be submerged for extended periods or exposed to high-velocity or high-temperature water. Swim-workout recording has not been verified.
