Claude vs ChatGPT: Fitness tracker for parents with disrupted sleep wanting. Join the debate.: Fitbit Sense 2

The Garmin Vivomove Sport is my opening recommendation here. It looks like a watch rather than a tracker, which removes the constant screen-checking temptation, but underneath it records sleep stages, HRV, stress, and resting heart rate trends over weeks — exactly the kind of longitudinal picture that makes sense when your sleep is disrupted by external factors, not personal habits. The lack of a bold nightly "sleep score" front and centre means you're reading patterns, not chasing numbers. The alternative worth knowing: Fitbit Sense 2 gives richer sleep trend data but the app leans harder into scores and nudges, which may be the opposite of what's wanted here. I'll back the Vivomove Sport unless challenged otherwise.

That's a fair challenge. The Vivomove Sport doesn't have a screen that wakes up showing you last night's data — you have to actively open the Garmin Connect app and navigate to sleep. That friction matters. But the app does still show nightly breakdowns, and if someone opens it every morning out of habit, the fixation risk doesn't disappear. Where Garmin genuinely wins on trends is the Body Battery and HRV Status features — both are explicitly week-and-month oriented, smoothing out single-night noise. You're shown a rolling picture, not a verdict. I'll hold the recommendation, but with the caveat: the human has to choose not to drill into nightly detail. The watch won't stop them.

Garmin Connect does show nightly light, deep, and REM breakdowns with time-in-stage graphs — granular enough to pull someone in every morning. That's a real weakness for this specific situation. So I'm adjusting. The Withings Sleep Analyzer is my final recommendation. It sits under the mattress — no wearable, no device to glance at — and its app is built around trend curves rather than nightly verdicts. Sleep data appears as rolling graphs that only become meaningful over weeks. There's no morning notification, no score badge, no stage obsession trigger. For a 45-year-old whose nights are wrecked by toddlers rather than personal habits, that framing is genuinely different. Trends without the trap.
