Fitbit did get the redesigned app Google promised—but it is no longer best described as a new Fitbit app. Google began replacing Fitbit with the Google Health app on May 19, 2026. The update brings reorganized navigation, Fitbit and Pixel Watch integration, social changes, and Google Health Coach, while the old Fitbit interface is not officially available as a rollback option.

The redesign was first announced on August 20, 2025, with dark mode and a Gemini-powered Personal Health Coach as its headline features. Here is what changed, what requires a subscription, and what existing Fitbit users should know before updating.

From a Fitbit redesign to Google Health

Google originally presented the project as a redesigned Fitbit app. The August 2025 preview promised a darker interface, simpler navigation, improved data visualization, better syncing, and a Personal Health Coach powered by Gemini. Google expected an initial Fitbit Premium preview in October 2025.

That framing is now outdated. Between May 19 and May 26, 2026, Google began moving users from Fitbit to the Google Health app. Google later said the redesigned app was available to Android and iOS users in version 5.0 by May 27, 2026. Fitbit Premium was also renamed Google Health Premium.

Google’s current transition information is available in its Google Health help documentation.

What users see in the new app

For users with a connected Fitbit device or Pixel Watch, Google Health is organized around four main tabs:

  • Today: an overview of daily activity and health information.
  • Fitness: workouts, activity and fitness-related guidance.
  • Sleep: sleep duration, stages, patterns and related insights.
  • Health: a broader view of health data and trends.

People using the app without a connected Fitbit or Pixel Watch receive a more limited experience centered on the Today and Health tabs.

The important change is therefore broader than dark mode. Google has restructured the Fitbit experience around the Google Health brand and a more consolidated view of fitness, sleep and health data.

What Google Health Coach does

Google Health Coach is the main new feature behind the redesign. Google describes it as a personalized, adaptive assistant built with Gemini. It can help eligible users create weekly fitness plans around their goals, preferences, available equipment, injuries and personal context.

Rank #2
Google Fitbit Air - Screenless Activity Tracker, Obsidian
  • Google Fitbit Air is the unbelievably comfortable, exceptionally smart way to transform your health[1]; and Google Health brings together effortless tracking and adaptive coaching to help make the most of your everyday[2]
  • Unlock more with Google Health Premium: With a premium membership, get personalized coaching that’s built with Gemini and adapts to your life[2]; get a 3-month trial at no cost to you[5] (Google Health Premium subscription sold separately)
  • Comfortable fit - One Size Tracker (130-210 mm): The lightweight, micro-adjustable fit sits comfortably and quietly, so you can wear Google Fitbit Air through work, play, and sleep; advanced sensors and new algorithms power more accurate, precise health tracking, 24/7[1]

  • Long battery life: Google Fitbit Air’s battery lasts up to a week, and fast charging gets you one day of battery life in just five minutes[6,7]

According to Google’s descriptions, the coach can also:

  • Adjust workout suggestions using daily metrics and how the user feels.
  • Use Fitbit or Pixel Watch data to provide context.
  • Offer sleep insights involving duration, stages, patterns and suggested schedules.
  • Answer questions about exercise, stress, sleep and weight-loss goals.
  • Use information from connected hardware and apps, including compatible smart scales.
  • Surface trends and recommendations instead of only displaying raw measurements.

These are wellness and fitness features, not a replacement for a doctor or other medical professional. AI-generated advice about injuries, sleep, stress or weight should not be treated as a diagnosis or treatment plan.

Is dark mode available?

Yes, dark mode was explicitly announced as part of the 2025 Fitbit redesign. However, Google’s current help documentation confirms the Google Health transition without documenting a universal dark-mode switch or a definitive Android and iOS menu path.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

That means users should not assume that every account, device or app build exposes an identical manual setting. The feature may depend on the app version, phone theme or staged availability. Avoid relying on old Fitbit screenshots or instructions that refer to menus from before the Google Health transition.

What is free and what requires Google Health Premium?

The redesigned Google Health app is broadly available, but Health Coach and premium coaching features require Google Health Premium. The subscription is the renamed Fitbit Premium service rather than an entirely unrelated product line.

Rank #3
Fitbit Sense 2 Health and Fitness Smartwatch - Shadow Grey/Graphite
  • Learn to manage stress, sleep better and live healthier with Sense 2 – an advanced health and fitness smartwatch
  • Manage stress and live healthier: All-day stress detection with cEDA and daily Stress Management Score, ECG app for atrial fibrillation assessment[1], irregular heart rhythm notifications[2], SpO2[3], health metrics dashboard[4], mindfulness content

  • Designed for all-day wear: On-wrist Bluetooth calls, texts and phone notifications[5], customizable clock faces, Amazon Alexa built-in[6], Google Wallet & Maps, 6+ day battery[7]

Google says new or returning Google Account users may receive a three-month Google Health Premium trial after updating. Google’s available support information does not establish a current standard monthly or annual price, so check the live Google Health Premium page before subscribing.

A subscription is not necessary simply to use the redesigned app or access ordinary device tracking. If dark mode is your only reason for updating, Premium may offer limited additional value; the principal premium attraction is Health Coach and related coaching features.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Who can use Health Coach?

Google’s current requirements include:

  • A connected Fitbit or Pixel Watch.
  • Google Health Premium membership.
  • Age 18 or older.
  • Residence in a country where the feature is supported.

Availability includes markets such as the United States, Canada, the United Kingdom, Australia, New Zealand, Japan, India and parts of Europe, but eligibility is not universal. Country availability, plan terms and supported features can change, so users should verify their account and region in Google’s current documentation.

What Fitbit users need to do

  1. Open Fitbit on Android or iOS and check for an available update.
  2. Install the Google Health update when it appears, or check the Google Play Store or Apple App Store manually.
  3. Sign in with a Google Account if prompted.
  4. Migrate a legacy Fitbit account if it has not already been connected to Google.
  5. Confirm the wearable connection and complete a sync.
  6. Review the new tabs and verify that recent activity, sleep and other important data appear correctly.
  7. Check privacy and social settings, since some Fitbit-era controls and profile behavior have changed.

Exact button labels may differ between Android and iOS. Do not uninstall the app before confirming that account migration and historical-data synchronization are complete.

Account, profile and social changes

Users with a standalone Fitbit account may need to migrate it to a Google Account. Google says the new social profile uses the Google Account name, email address and profile picture, so custom Fitbit usernames and photos are not supported in exactly the same way.

Social features were temporarily restricted in the old Fitbit app beginning May 12, 2026, ahead of the transition. After moving to Google Health, users can again manage friends and compete on weekly leaderboards, including leaderboards based on steps and Cardio Load.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Because the transition changes account and privacy behavior, users should review their profile visibility and sharing settings rather than assuming every Fitbit preference transferred identically.

Can you restore the old Fitbit app?

Users should not expect an official switch that restores the previous Fitbit interface. Google’s employee response to questions about the old app describes Fitbit as superseded by Google Health and directs users to Google Health support resources instead of offering a rollback.

Historical information may still be present, but its presentation, navigation and social settings can differ. Google’s documentation does not guarantee that every historical metric or setting will appear identically after migration.

What to do if the update or data does not appear

  • Check the Play Store or App Store manually.
  • Confirm that the phone meets the app’s current operating-system requirements.
  • Complete Google Account migration if requested.
  • Make sure the Fitbit or Pixel Watch is online and syncing.
  • Restart the app and allow synchronization to finish before judging missing data.
  • Use current Google Health help pages rather than old Fitbit setup guides.

Some users have reported dissatisfaction with the new interface or sleep data in Google’s support community. Those reports are user feedback, not proof of a universal technical failure. If sleep or another important metric looks wrong, preserve the device and account state while checking official support guidance rather than immediately uninstalling the app.

Should you update?

Existing Fitbit owners

Generally yes, if you want continued access to the supported Fitbit experience. Google’s transition treats Google Health as the replacement for Fitbit, so remaining on the old interface is not a dependable long-term option.

Fitbit Premium subscribers

Update if you want the current coaching features. Your subscription lineage continues under the Google Health Premium name, but check the account page to confirm plan status and any trial or billing terms.

Users who mainly want dark mode

Update for the newer app, but do not subscribe solely for dark mode unless you also value Health Coach and other premium features. Google has not documented one universal dark-mode setup path for every current build.

Data-focused users and athletes

Inspect the new layout before paying for Premium. Health Coach is designed around adaptive recommendations, not necessarily the detailed training analytics, GPS tools, recovery analysis or structured workouts that serious athletes may prefer from platforms such as Garmin, Apple Watch, Samsung Galaxy Watch or Polar.

Privacy-sensitive users and families

Review Google Account, health-data and social settings after migration. Health Coach eligibility also requires users to be at least 18, so it is not a universal option for younger users.

The bottom line

Fitbit’s promised redesign arrived, but the product evolved into the Google Health app rather than launching as a permanently separate new Fitbit app. The meaningful changes are the Google rebrand, reorganized Today/Fitness/Sleep/Health navigation, Google Account migration, updated social features and optional AI coaching—not just a darker color scheme.

For most existing Fitbit users, updating is the practical path forward. The key decision is whether Google Health’s account model and subscription-based Health Coach fit your needs. The old Fitbit interface should be treated as retired, and Health Coach should be treated as a wellness assistant—not medical advice.
