Our top picks

Most people with an iPhone should get the Apple Watch SE 3. Get the Fitbit Charge 6 if you use an Android phone, want about a week of battery, or want to spend less.

Looking at a simpler band? See our Garmin vs Fitbit guide.

The phone in your pocket settles most of this. The Apple Watch is set up with an iPhone, while the Fitbit works with Android and iPhone.

Pros and cons

Why it made the list

  • About a week of battery on a charge, per the listing.
  • Works with Android and iPhone.
  • Built-in GPS, 40+ exercise modes and 24/7 heart rate in a slim band.
  • Google Maps directions, Google Wallet payments and YouTube Music controls.
  • It can show your heart rate on compatible treadmills and other gym machines.

Drawbacks

  • Owners are split on reliability. Some units last more than a year, and others stopped working or stopped syncing with the phone after a few months.
  • Two owners say the GPS distance or calorie numbers looked wrong.
  • The 3-month Google Health Premium trial ends, and some coaching and score details need the paid plan.
  • Music controls work with YouTube Music only, and the side button only wakes the screen, one owner says.

Skip it if you want a full smartwatch with calls, apps and a big screen.

The short version

  • Have an iPhone and want one device for calls, texts, payments and workouts? The Apple Watch SE 3.
  • Have an Android phone? The Fitbit Charge 6. Garage Gym Reviews says an Android workaround for the Apple Watch exists, but it needs someone with an iPhone.
  • Hate charging every night? The Fitbit. Its listing says up to 7 days, and the Apple Watch’s says up to 18 hours of normal use.
  • Want the smallest, lightest thing on your wrist at night? The Fitbit band.
  • Want fall and crash detection, and a bigger, brighter screen? The Apple Watch.

How to choose between them

Garage Gym Reviews compared the Charge 6 with Apple’s Series watches and calls the Charge 6 more of a fitness tracker and the Apple Watch a smartwatch. That matches what the two Amazon listings show.

  • Screen. The Apple Watch has a 44mm always-on OLED screen that reaches 1,000 nits. The Fitbit has a 1.04-inch AMOLED screen on a slim band.
  • Battery. The Fitbit lists up to 7 days. Garage Gym Reviews says the always-on display and blood-oxygen features drain it faster. The Apple Watch lists up to 18 hours of normal use, or 32 in low power mode.
  • Phone. The Apple Watch needs an iPhone. The Fitbit lists Android 11 and up and iOS 16.4 and up.
  • Health features. Both track heart rate, sleep and workouts with built-in GPS. The Apple Watch SE 3 adds sleep apnea notifications and temperature sensing, and lacks the ECG and blood-oxygen apps that Apple’s pricier watches have. The Fitbit gives a daily sleep score and a stress score.
  • Subscriptions. The Fitbit includes a 3-month trial of Google Health Premium, which is a paid plan after that. The Apple Watch listing mentions free trials of Apple’s services, with terms.
  • Weight. The Apple Watch listing gives 32.9 grams. The Fitbit listing gives case size only.

What owners complain about

  • On the Apple Watch SE 3: battery that needs charging daily, a band that runs small for some wrists, and no ECG app. A wheelchair user found step counting weaker than on a cheaper Fitbit band.
  • On the Fitbit Charge 6: units that stop syncing or stop working, step and distance numbers that do not match gym machines, a band one owner found uncomfortable, and charging contacts that corroded for one owner after about two and a half years.
  • On both: battery life gets mixed reports, with some owners happy and others charging far more often than the listing suggests.

What we left out, and why

We read two listings and 16 reviews.

  • Cellular models. The Apple Watch SE 3 also comes in a GPS plus cellular version at a higher price. We read the GPS listing only.
  • Apple Watch Series and Ultra, Google Pixel Watch. Amazon’s compare charts list them, but they cost far more and answer a different question.
  • Other Fitbits. The Charge 6 is the one most shoppers compare with an Apple Watch. The same Amazon page lists newer Google trackers, which we did not read.
  • The 40mm Apple Watch. Most of the reviews name this size. We compared the 44mm listing.

How we researched

On October 14, 2026 we read the Amazon listing pages for the Apple Watch SE 3 (GPS, 44mm) and the Fitbit Charge 6. We read each page's bullets and specs, Amazon's review summaries and the lower-star reviews we could see. We also read Garage Gym Reviews' comparison of the Charge 6 and the Apple Watch and checked Google's top results for this question. AI wrote this guide from that research.

The Fitbit listing gave no weight, and the Apple Watch listing's reviews cover several sizes and colors of the SE 3, so most name the 40mm case. We compared one size of each, GPS only. Garage Gym Reviews compared the Charge 6 with the older Series 9 and 10, so we use it only for facts that do not depend on the watch.

Frequently asked questions

Is Fitbit or Apple Watch better for fitness tracking?

Both track workouts, heart rate and sleep with built-in GPS. The Fitbit lasts longer between charges. The Apple Watch has a bigger screen and more smartwatch features, so most iPhone owners prefer it.

Can you use an Apple Watch with an Android phone?

Not in practice. An Apple Watch is set up with an iPhone, and Garage Gym Reviews says the Android workaround needs someone with an iPhone. The Fitbit works with Android and iPhone.

Does the Fitbit Charge 6 need a subscription?

No, the basics work without one. It includes a 3-month trial of Google Health Premium, and some coaching and score details need the paid plan after that.
