Review: Great Kids’ Fitbit with Minimal Issues - Overall, this kids’ Fitbit has been a great purchase! The battery life is impressive — it easily lasts over a week, even with 24-hour wear. The sleep tracking option is a nice bonus, and it’s waterproof, which gives me peace of mind when my kid forgets to take it off for showers or swimming. The only downsides are that we had to buy a new charger after the original one stopped working within a few months, and the watch only syncs the correct time when it’s regularly connected to Bluetooth. Despite those minor annoyances, it’s a fun and motivating fitness tracker for kids. I’d still recommend it!

### ⭐⭐⭐⭐⭐ Great Kids’ Fitbit with Minimal Issues

### ⭐⭐⭐⭐⭐ Fitbit Ace 3 for Children
*by T***L on January 22, 2026*

A great little first watch for our daughter. She loves it.

### ⭐ Absolute Trash Setup Process
*by T***N on December 25, 2023*

**UPDATED REVIEW** Let me hopefully save you some headache. If you have an Android device, it seems that this process is a bit easier and the Fitbit app accepts a kid's Google account; however, if you only have iOS devices these are the issues, and the resolution: 1) The Ace 3 is designed for kids, but... 2) It REQUIRES a kids Google account, (and now that Google owns Fitbit, there are no non-Google accounts allowed to be created on Fitbit) 3) Anyone under 13 has to have a supervised Google account 4) Fitbit engineers overlooked this MAJOR detail and supervised accounts don't work on Fitbit right now 5) Changing an non-kid account to a kid account (via a birthdate change) doesn't work; Fitbit now says this type of account can't be used. 6) So, the only way it seems to make this work is to create a brand new child Google account FROM THE GOOGLE FAMILY DASHBOARD. If you don't create it from there, it won't work. I burned multiple Google accounts trying other ways. 6) I still think the setup process makes this worth one star at best. It's absurd that a product made for kids can't just be setup easily. It's also absurd that Fitbit requires all Google accounts, but hey DATA. 7) The dumb part is the Charge 6 we bought for our older child was so simple to set up. Everything worked the first time and it was done in 30 seconds. **ORIGINAL REVIEW** Would give zero stars if possible. Google, get your crap together. Setting up an Ace 3 on a supervised Google account doesn't work in the Fitbit app that you've now broken. And GUESS WHAT, a kid under 13 HAS TO HAVE A SUPERVISED GOOGLE ACCOUNT. Oh, I know, I'll just use a Google account with an older birthdate on it — NOPE, NOW THE FIBIT APP SAYS THAT'S NOT A KID ACCOUNT. Fix your junk and stop ruining Christmas for kids.
