Many trackers measure sleep, HRV, and recovery in ways JOIN cannot on its own. You can use this data to supplement your JOIN Readiness score. Always let your own feeling lead — no tracker score should override how your body actually feels.
Oura Ring
JOIN now has a direct integration with the Oura Ring. Connect your Oura account under Connected Accounts in JOIN and your Oura Readiness Score will be used automatically. You can still adjust your Readiness manually if it does not match how you feel.
For reference, here is how the scores compare:
| Oura Score | Oura Label | JOIN Equivalent |
|---|---|---|
| 0–59 | Low / Pay attention | 0–40 |
| 60–69 | Fair | 40–50 |
| 70–100 | Optimal / Good | 50–100 |
Whoop
A direct Whoop integration is coming soon. In the meantime, you can manually use your Whoop Recovery Score to adjust your JOIN Readiness. The score ranges map fairly directly:
| Whoop Score | Whoop Label | JOIN Equivalent |
|---|---|---|
| 0–33 | Red / Not ready | 0–30 |
| 34–66 | Yellow / Moderate | 30–50 |
| 67–100 | Green / Ready | 50–100 |
In the 34–66 range especially, use your own judgement alongside the score.
Garmin
Garmin provides a Readiness Score between 0 and 100. A deeper integration is limited due to Garmin API restrictions, so for now you can manually use the score to inform your JOIN Readiness.
| Garmin Score | Garmin Label | JOIN Equivalent |
|---|---|---|
| 0–25 | Low | 0–30 |
| 26–50 | Moderate | 30–50 |
| 51–100 | Good / Optimal | 50–100 |
Fitbit
Fitbit tracks sleep, HRV, and activity and provides a Daily Readiness Score with three zones. There is no direct Fitbit integration in JOIN, but you can use the score manually.
| Fitbit Score | Fitbit Label | JOIN Equivalent |
|---|---|---|
| 1–29 | Low | 0–30 |
| 30–64 | Good | Use your own feeling |
| 65–100 | Excellent | 50–100 |
For scores between 30 and 64 we recommend not taking the Fitbit number directly into JOIN — use how you actually feel instead.
Other trackers
Polar and Suunto integrations are not planned at this time. For any tracker not listed here, only adjust your JOIN Readiness when there is a meaningful difference between what JOIN shows and what your body or tracker is telling you — for example, after poor sleep or a high-stress day JOIN would not otherwise know about.
