Fitbit was the brand that made step counting mainstream, and its Android app is now a Google product in everything but the logo. Google closed its acquisition of the company in 2021, and since then long-time users have been moved onto Google accounts, the app has been redesigned around Google's design language, and features have shifted between free and paid tiers more than once.
The app itself is the companion to Fitbit trackers, smartwatches, and Google's Pixel Watch; without one of those on your wrist, most of it sits empty. Pair a device and you get sleep staging, heart-rate trends, exercise tracking, and stress metrics — though deeper analysis, including the Daily Readiness score and long-range trend breakdowns, sits behind the Premium subscription. The middling Play Store rating reflects a user base that has weathered a lot of change, not an app that fails at the basics.
Daily companion for a Fitbit or Pixel Watch
This is the app's real job: syncing your wearable, showing steps, sleep, heart rate, and workouts, and managing device settings, watch faces, and notifications. If you own the hardware, installing it is not optional — everything routes through here.
Sleep tracking over months
Fitbit's sleep staging and nightly Sleep Score are among the more mature in consumer wearables, and long-term trends can reveal patterns worth acting on. The catch is that several of the richer sleep breakdowns now require Premium.
Health metrics at a glance
Resting heart rate, heart-rate variability, breathing rate, and skin-temperature variation (on supported devices) collect into a health dashboard. None of it is diagnostic, but sustained deviations from your baseline can be a useful prompt to see a doctor.
Device sync and management
Pairing, firmware updates, clock faces, alarms, and notification settings for every current Fitbit device live in the app. Sync is usually automatic in the background, though users periodically report Bluetooth sync failures after app or Android updates.
Sleep Score and staging
Supported devices break nights into light, deep, and REM sleep and summarise them as a single score. The free tier shows the score and stages; Premium adds the detailed breakdown of what drove the number.
Exercise and active zone minutes
Workouts are detected automatically or started manually, with GPS from the watch or phone. Active Zone Minutes credit time spent in elevated heart-rate zones, a more meaningful target than steps alone for people who train.
Premium insights and Daily Readiness
The subscription layers on Daily Readiness (a recovery score), a wellness report, guided workouts, and mindfulness sessions. How much of that feels essential versus artificially gated is the central argument long-time users have with the product.
