Both the Fitbit Alta HR and Fitbit Ace 2 are excellent choices for anyone who’s looking to limit their spending on a fitness tracker and aren’t concerned with the bells and whistles that more advanced trackers have.

Fitbit Ace 2 vs. Fitbit Alta HR – Short Answer:

Unless you want a pedometer that reminds you to move and can track sleep, you should opt for the Alta HR.

As the name implies, it comes with heart-rate monitoring and gives you a lot more insight into your activity patterns.

Most importantly, its design definitely beats the Ace 2 as it doesn’t look like a kid’s bracelet.  

Fitbit Ace 2 vs. Fitbit Alta HR – Full Comparison:

1. Design and Display

With minimalistic features comes a minimalistic design. Both these trackers have the famous bracelet design of the Fitbit devices with the vertical grayscale screen. There isn’t much to either Fitbit, but they’re both pretty sleek and can be super inconspicuous on the wrist.

Except maybe that the Ace 2 has vibrant colors that draw some attention to it.

By tapping Fitbit twice, you activate it. Then, you can keep tapping to check out different metrics, which we’ll talk about later.

The metrics might be a little easier to check on the Alta HR as its 1.1-inch display, which is a little bigger than the Ace 2’s 0.8-inch one.

Winner: Fitbit Alta HR

2. Fitness and Health Features

Now, moving on to the important aspects of fitness trackers: their ability to monitor and log your activity.

You shouldn’t be expecting a lot from either device, but if you want more than just basic step-counting, you should opt for the Alta HR.

The Ace 2 only serves as a pedometer that can track the duration of your sleep as well. It doesn’t include stages of sleep like more advanced Fitbit devices such as the Versa or the Charge 3.

It also has reminders to move to help you reach a 250-step hourly goal, which the Alta HR also has to offer.

Perhaps the only way the Ace 2 beats the Alta HR is that it’s swim-proof up to 165 feet while the Alta HR is only sweat-, rain-, and splash-proof.

For someone who’s not concerned with water-resistance, the Alta HR would be a better fitness tracker as it comes with 24/7 heart-rate monitoring, which also serves to enhance sleep-tracking with its stages (REM, light, and deep) and measure the user’s fitness level.

It also comes with SmartTrack that enables the user to choose certain activities to be detected and logged automatically, so it offers more than just step-counting and calorie-tracking.

Winner: Fitbit Alta HR

3. Smart Features

In terms of smart features, the Ace 2 is only capable of delivering call notifications.

While the Alta HR doesn’t do much more, it can still deliver notifications of calls, texts, and apps to your screen.

Winner: Fitbit Alta HR

4. Battery Life

Surprisingly, the Fitbit Alta HR comes with a superior battery life despite having more features, especially a heart rate monitoring capability. With a battery that lasts seven days, it beats the Ace 2, which can only last five days on a single charge.

Winner: Fitbit Alta HR

Fitbit Ace 2 vs. Fitbit Alta HR: Final Thoughts

Unless you’re looking for a swim-proof option or you really don’t want to spend that extra fifteen bucks, you should opt for the Alta HR.

It easily beats the Ace 2 in every aspect, but the most important thing is that it has a more adult-suitable design that you can actually step into an office wearing.

Of course, if you’re buying the Fitbit device for a child, it goes without saying that you should opt for the Fitbit Ace 2 as it comes with a family account.
