Apple rates it for up to 24 hours of normal use, up to 38 hours in Low Power Mode, and up to 10 hours of workout tracking, and lists an S11 chip. Choose the Fitbit Air if you want a lower-priced, screenless tracker for 24/7 heart rate and sleep. Google rates it for up to 7 days and the Google Store lists it from $99.99. Neither is better for everyone; it depends on whether you want a full smartwatch or a screenless tracker.","answer_curated":true,"verdict":"Best full smartwatch on an iPhone: Apple Watch Series 12.

Fitbit Air is hardware. The Google Store lists it from $99.99. The May 2026 launch post also included a three-month Google Health Premium trial that renews at $9.99 a month unless you cancel, and Google says some features require that membership. Whoop is a membership product. No Whoop price is stated. The asker had already decided Whoop felt like more than they needed. There is no live Apple Watch Series 12 versus Whoop comparison, so no link is included."},{"question":"Which is better for sleep, Apple Watch Series 12 or Fitbit Air?","answer":"Neither device is ranked as more accurate for sleep. Apple lists a Sleep app that includes sleep stages, a sleep score, and Sleep apnea notifications, on a watch rated for up to 24 hours of normal use. The same Health and Wellness list includes a Vitals app with heart rate, respiratory rate, wrist temperature, sleep duration, and heart rate variability. Apple says: \"The temperature sensing feature is not intended for medical use.\" Google lists sleep stages and sleep duration on the Fitbit Air. The 7 May 2026 launch-post footnotes also say \"Not intended for medical purposes.\" Google Health Help rates that tracker for up to 7 days. Google's vitals table marks the Air for skin temperature variation, SpO2, heart rate variability, breathing rate, and resting heart rate. The longer battery rating is the practical difference for wearing it through several nights. It is not an accuracy score."},{"question":"Do you need cellular on the Apple Watch Series 12?","answer":"No. Apple lists a GPS model and a GPS + Cellular model. Cellular is the option for calls and data when the iPhone is not with you. Gym tracking, sleep tracking, and notifications while the phone is nearby do not require it. The asker was leaning toward a 42mm cellular watch. That is a choice, not a requirement."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/apple-watch-series-12-vs-fitbit-air","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/apple-watch-series-12-vs-fitbit-air), Choose the Apple Watch Series 12 if you want a full smartwatch: apps, notifications, and an optional cellular model, on an iPhone.
