Sarvita vs Death Clock

Two AI-powered longevity apps with very different approaches. One gives you a training plan. The other gives you a death date. Here's how they compare.

Last updated: February 2026 · Back to Sarvita home

TL;DR

Death Clock predicts your death date using AI trained on CDC mortality data, then builds a clinical longevity protocol targeting heart disease, cancer, diabetes, and dementia. It's blood-work-centric — subscriptions include lab tests at 4,200+ US locations.

Sarvita calculates your biological age from fitness metrics (VO2 Max, HRV, body composition), then gives you an AI coach with weekly training plans, daily check-ins, and nutrition tracking to make that number go down.

Key difference: Death Clock is clinical and blood-work driven ($99–$299/yr, US-focused). Sarvita is fitness and nutrition driven ($12.99/yr, works anywhere).

Different Philosophies

🟦 Sarvita — Train Your Way Younger

Sarvita calculates your biological age from VO2 Max, HRV, and body composition — all metrics you can improve through training. Then Sar, your AI coach, builds weekly plans around the 4 pillars of longevity: Zone 2 cardio, strength training, VO2 max intervals, and stability work. The focus is on what you can do today to get younger.

⬜ Death Clock — Know Your Numbers

Death Clock predicts your death date using AI trained on CDC mortality data and your lifestyle inputs. Its core product is the "Life Lab" — a clinical protocol built around preventing the "Four Horsemen" (heart disease, cancer, diabetes, dementia). Blood work is central: 25+ biomarkers across hormones, inflammation, cholesterol, and metabolic health.

Bottom line: Sarvita asks "how old is your body?" and helps you make it younger through fitness and nutrition. Death Clock asks "when will you die?" and tries to push that date further away through clinical intervention.

Frequently Asked Questions

Can I use both Sarvita and Death Clock? ▼
Absolutely. They complement each other well — Death Clock for clinical blood work and disease prevention, Sarvita for daily training programming and nutrition. Use Death Clock to know your numbers, Sarvita to act on them.
Is "biological age" the same as "life expectancy"? ▼
No. Biological age (Sarvita) measures how old your body is right now based on fitness markers. Life expectancy (Death Clock) predicts when you'll die based on mortality models. Both are useful — biological age shows your current state, life expectancy shows projected outcome.
Does Death Clock work outside the US? ▼
The app works worldwide, but blood work is only available at partner locations in 49 US states (for users 18+). Outside the US, you can still upload your own lab results, but you won't get the integrated blood draw booking.
Which is better value for money? ▼
Depends on what you need. If you want daily AI coaching and meal tracking, Sarvita at $12.99/year is hard to beat. If you want clinical blood work and a longevity protocol, Death Clock's Baseline at $99/year includes actual lab tests — which would cost more out of pocket. Both offer genuine value at different price points for different needs.
