Fitbit Ace Overview



  • Comfortable to wear
  • Many useful functions
  • Great display


  • A little overpriced

In Conclusion: Which Is Better Fitbit Ace or Alta Overall?

In conclusion, the differences between the Fitbit Alta and Fitbit Ace aren’t that big, and the extra features that the Fitbit Alta has to offer may seem secondary and could be easily overlooked.

However, the fact that the Ace was mainly targeting little children when it launched puts a consumer who is considering it in a tight spot where it doesn’t have except one option for the size.

It also lacks some features like Caller ID and text notifications, SmartTrack, and water resistance.

There are some more features that are more vital that the Ace isn’t equipped with like heart rate monitoring and GPS services, but in the comparison between the Ace vs the Alta, that doesn’t make a difference because the Alta lacks them as well.

The Ace is way more affordable than the Alta for the difference in features.

So to keep things short, if you can make do without the little extra features, want to save up, and the Ace’s single size is suitable for you, then you should go for it. If you’re bent on having the extra features, then go for the Alta.
