WHOOP alternative
Garmin as a WHOOP alternative
Garmin owners are the group WHOOP has the hardest time selling to, and for a good reason: a Garmin already does the always-on part. Two to four weeks of battery on many models means the watch simply never comes off, which is the exact behaviour recovery scoring depends on. What Garmin Connect gives you back is a wall of proprietary metrics. Lamplit turns them into three numbers and a reason.

Is Garmin a good WHOOP alternative?
Yes — and on the wear-time dimension, a Garmin arguably beats WHOOP outright. The band's headline advantage is that you never take it off; a Fenix or an Instinct clears that bar with weeks to spare, and it has a screen. Garmin also publishes its wellness data outward, into Apple Health on iPhone and Health Connect on Android, which is the doorway Lamplit uses.
The honest complication is which metrics come through that doorway. Garmin's published Health Connect set covers heart rate, sleep, steps and distance, calories, floors, weight and body fat — a strong list, but heart-rate variability and VO₂ max are not on it, and reports of them crossing on iPhone vary by model and firmware. That is why both are marked "varies" above rather than promised. It matters less than it sounds: Readiness renormalises over the components it can actually see, so a Garmin that sends sleep, resting heart rate and workouts still produces a real score built on three of its four inputs, rather than a broken one.

| Metric | Reaches Lamplit |
|---|---|
| Heart-rate variability | Varies |
| Resting heart rate | Yes |
| Sleep duration, stages & timing | Yes |
| Workouts with heart-rate zones | Yes |
| Steps & active energy | Yes |
| VO₂ max | Varies |
| Weight, body fat & lean mass | Yes |
Depends on your model, firmware or platform — Readiness adjusts to what actually arrives.
Check the toggles inside Garmin Connect before you judge the result — the integration is opt-in per category, and it is easy to leave sleep or heart rate switched off. Garmin's bridge is also one-way and backfills only about two weeks of history when first enabled, so your Lamplit baselines start from the day you connect it, not from your whole Garmin archive.
The three scores that stand in for WHOOP's
Readiness — the recovery score
Readiness answers the question WHOOP's Recovery percentage answers: how much have you actually got today? It is a 0–100 weighted score over four inputs — heart-rate variability against your own rolling baseline, last night's sleep, your acute-to-chronic training load, and resting heart rate. It renormalises over the inputs it can genuinely see, so a device that publishes sleep and heart rate but not HRV still returns an honest score instead of a broken one. Below about a third of coverage it declines to guess and shows nothing at all.
Effort — the strain score
Effort is the day's training load on a 0–100 scale, built from heart-rate-zone minutes converted into moderate-equivalent minutes and scaled against the World Health Organization's 150-minutes-a-week guidance. Where WHOOP's Strain is a proprietary 0–21 curve, Effort is a published formula you can check: vigorous minutes count double, and a day with no readable zone data says so rather than inventing a number.
Lamplit Age — the biological-age estimate
Lamplit Age is the counterpart to WHOOP Age — an estimate of how your habits and measurements compare with the years on your passport, expressed as an offset in either direction, plus a pace-of-aging figure. It runs nine inputs over a rolling 28-day window: resting heart rate, VO₂ max, sleep duration, sleep quality, sleep consistency, steps, heart-rate-zone minutes, strength work and lean-mass index. Missing inputs are dropped rather than replaced by an average, which pulls a sparse profile toward your real age instead of flattering it. Every coefficient and the study behind it are published at lamplit.ai/methodology.

Best for
- You own a Garmin and the multi-week battery means you already wear it around the clock
- You want a recovery score without paying for a second wrist device
- You've hit the ceiling of what Garmin Connect's dashboards will tell you to actually do
- You want training load read alongside food, fasting, mood and sleep rather than on its own
The honest caveats
Heart-rate variability is Readiness's most informative input, and Garmin is the one source here where its arrival is not guaranteed. If your model and platform don't pass it through, Readiness runs on sleep, resting heart rate and training load — genuinely useful, but a step below what an Apple Watch or a Pixel Watch feeds it. Garmin also declines to read anything back from Apple Health or Health Connect, so this is a one-way street: nothing you log in Lamplit will appear in Garmin Connect.
Lamplit ships no hardware, and it isn't going to. It reads what your device's own app already computed, so it cannot sample your heart rate around the clock and it cannot notice a workout that nothing recorded. A screenless sensor that runs for days and never comes off is the thing WHOOP genuinely sells, and no software layer replaces it.
Wearable sync is a Pro feature at $5.99 a month. Readiness, Effort, Lamplit Age and the Longevity Score are free on every plan — but on the free plan they run on what you log by hand, not on what your watch measured.
Your device's numbers are your device's numbers. Lamplit does not re-derive heart-rate variability from a raw signal; if your wearable's sleep staging runs optimistic, Lamplit inherits that. Changing devices mid-year will show up as a step change in your baselines, and the app will not pretend otherwise.
None of these scores is a medical device, a diagnosis or a prediction about your lifespan. Neither is WHOOP's. The difference is that Lamplit's methodology is published in full, so you can see exactly which association each number rests on.
What it actually costs
Garmin charges nothing for the sync — Connect+ at $6.99 a month exists, but its AI insights and dashboards are not needed for any of this. So the comparison is Lamplit Pro at $5.99 a month against a WHOOP membership at $199–$359 a year, on a watch you already own and already wear.
Getting set up
- In Garmin Connect, open Settings → Connected Apps and enable Apple Health (iPhone) or Health Connect (Android).
- Switch on every category offered — especially sleep, heart rate and body composition. Anything left off simply never reaches Lamplit.
- Grant Lamplit read access to the same store, then give it a week to build baselines before reading Readiness.
