Question 1

Is the Exclusive Launch Offer free?

Accepted Answer

Yes. The Exclusive Launch Offer is completely free with no credit card required. You get full access to all features during early access and lock in a lifetime discount when we launch.

Question 2

How is 8gevity different from other health apps?

Accepted Answer

Other apps show you data. 8gevity gives you a personal AI Coach that analyzes ALL your data sources together — wearables, bloodwork, lifestyle — and creates a Digital Twin that predicts how specific changes will improve YOUR health over time.

Question 3

How does the AI Coach personalize recommendations?

Accepted Answer

The AI Coach analyzes your connected data (sleep, HRV, activity, bloodwork) to build a Digital Twin — a personalized model of your biology — and uses peer-reviewed research to predict which protocols will work best for you specifically.

Question 4

Do I need bloodwork?

Accepted Answer

No. Bloodwork is optional. You can start with just wearable data from devices you already own. Bloodwork adds deeper insights, but the platform works great with wearables alone.

Question 5

Which wearables can I connect?

Accepted Answer

8gevity supports Oura, Fitbit, Garmin, Apple Watch, Strava, Withings, WHOOP, Polar and many more through integrations with leading health data platforms.
