Whoop vs Radiant Health
Whoop is a strap that scores recovery and strain. Radiant Health is an AI coach that turns those numbers into a daily plan, plus everything from supplements to training-load math. Here is how they compare on the things that actually change a training week.
| Capability | Whoop | Radiant Health |
|---|---|---|
| Hardware required | Yes (strap) | No |
| HRV-based recovery score | Yes | Yes |
| Goal-aware morning briefing (push) | No | Yes |
| AI coach chat | No | Yes |
| Supplement engine + safety screening | No | Yes |
| TSS / TSB training-load math | Strain only | Yes |
| Garmin, Oura, Fitbit, Pixel Watch | No | Yes (via Health Connect) |
| Free tier | No | Yes |
Where Whoop is strong
Whoop's strap is one of the better consumer HRV sensors and the proprietary recovery score is well-tuned. If you are a hardware-first athlete and you already own one, keep wearing it.
Where Radiant Health goes further
The gap most users feel after a few weeks of Whoop is "OK, recovery is yellow today — now what?". Radiant Health pairs the same kind of HRV / sleep / training-load signal with a coach that produces an explicit prescription: which session, which intensity, which supplement, which nudge to take or skip. We pull data from any sensor you already own and skip the strap requirement.
Best of both
Connect a Garmin or Health Connect device to Radiant Health. Keep your Whoop strap for the strain workflow if you like it. The coach reads whichever signal is cleanest and gives you one daily plan instead of three apps.

Indirectly. Whoop has no public consumer API yet. Most users run Garmin, Oura or a Health Connect device alongside Whoop and let Radiant Health do the coaching while Whoop stays on the wrist.
Does Whoop give training advice?
Whoop gives a daily strain target. Radiant Health goes further with a session-by-session prescription, supplement nudges, and recovery-block suggestions tied to your goal.
What is the price difference?
Whoop requires the strap and a subscription. Radiant Health has a free tier and works with sensors you already own.
