Rolls wearables, lab work, and DNA scattered across apps into one score, then answers what is going on with your body.
Public materials do not yet show how users complete this job today or what they replace.
The product targets friction in this job, but public user evidence does not yet show the cost, frequency, or consequence of leaving it unsolved.
Health data sits in eight apps, and nothing flags a trend before it turns. Don't build another wearable—help people who already have too much data but cannot read it, by collapsing the scatter into one sentence they can act on.
It promises a simpler way to complete this job: Rolls wearables, lab work, and DNA scattered across apps into one score, then answers what is going on with your body. The exact adoption motive and repeat use are not yet verified.
① Whether App Store/Google Play ratings and downloads materialize (5+ downloads is; zero); ② Whether any independent medical/health review validates the Healthspan Score; methodology — a score needs a reviewable model behind it, or it is packaging; ③ Vaya Chat's real-world accuracy and hallucination…

An English validation note will follow from the public evidence.
The product claims to help users complete: “Rolls wearables, lab work, and DNA scattered across apps into one score, then answers what is going”. User evidence has not yet verified pain intensity or the cost of doing without it.

The call and next move come first; the full read retains the evidence and counterevidence.
Collapses wearables, labs, DNA, nutrition, and medical records — dozens of data sources — into one healthspan score, with an AI coach answering "what is actually happening to my body."
CEO Kevin Amrelle (his profile lists him as Executive Director of AI/ML at Wells Fargo, and that role is still marked "current"), with co-founder Dr. Duddu Venkata Ramana (Head of AI & Data Science). The product previously ran as Vitality AI Health (launched May 2026) and was renamed Vidaya after colliding with insurer Vitality's own "Vitality AI" (built with Google). Launched at launch the week of August 2026, daily rank #9.
Read: the pool lists Kruti Parekh as builder, which conflicts with public material (Kevin Amrelle); likely the submitter rather than a founder. Treat the company's public account as authoritative. And a product that had to give up its name to an insurer is a product without enough moat to defend its own name.
Answering "how is my body actually doing" used to mean logging into eight apps: meals in MyFitnessPal, supplements somewhere else, blood work as a PDF from Quest, DNA in 23andMe, medical history locked in Epic, steps in Apple Health, air quality on an EPA dashboard. Nobody connected them. It replaces the scattered state of personal health data plus "the user as their own data analyst."
The founder's trigger is genuine and firsthand: his heart rate capped at 120 BPM during a winter bike race, then stage 2 hypertension — and no health app caught the trend. That pain is real, but "catching the trend" is exactly the promise aggregate- health products struggle hardest to keep, because it needs long, continuous, multi-dimensional data, and most users never reach that threshold.

| Dimension | Call |
|---|---|
| Founder-product fit | A real personal health event and an AI background (claims to have built the bank's first end-to-end RAG), but full-time commitment is in question |
| Product insight | The aggregate → compress → answer structure is clean; the dual-score design (healthspan + data-completeness) is smart |
| Execution quality | Claims a 32-question stress suite and an LLM-as-judge stack, none of it publicly verifiable |
| Timing | Crowded: Apple Health/Whoop/Oura are aggregating natively, Levels/SiPhox own verticals. Weak positioning against free aggregation |
The problem is real, the story is real, and the validation is zero. Three structural problems:
First, no evidence. Three months post-launch: 5+ Google Play downloads, no App Store rating, no third-party review, no funding. A health-data product with no verifiable usage footprint after three months has a story, not traction. Trust in health data is bought with independent review, not copywriting.
Second, it competes on the wrong plane. Apple Health, Whoop, and Oura are all building aggregation into the system; Levels (CGM + metabolism) and SiPhox (at-home labs) dig vertically. "60+ sources plus one score" has no defense against free native aggregation. The claimed differentiator — the cross-source correlation engine — has zero verifiable outputs showing a correlation finding was actually correct (cross-source correlations are the easiest place to manufacture false ones).
Third, founder commitment is in question. The Wells Fargo executive role is listed as current, with parallel ventures running. For a health startup that needs full-time dedication, that is a real risk signal — and health-data products are the worst category to abandon mid-way, because the user's health data lives inside them and depends on the product surviving.
Read: "Unproven" is not because the product is bad; it is because it currently has a story and no evidence. Hallucination in health costs far more than hallucination in a code patch — a wrong "healthspan score" does more damage than a wrong commit.
① Whether App Store/Google Play ratings and downloads materialize (5+ downloads is zero) ② Whether any independent medical/health review validates the Healthspan Score methodology — a score needs a reviewable model behind it, or it is packaging ③ Vaya Chat's real-world accuracy and hallucination rate — the error tolerance in health Q&A is zero
Product logic: collect every health signal a person generates, compress it into one score, answer it through one chat surface — the aggregate → compress → answer structure transfers to any fragmented-data domain (finance, supply chain, project management), with one precondition: prove the compressed number is trustworthy first.
Pricing structure: a clear disclaimer (not a medical device, informational only, data exportable and deletable) — skip the liability boundaries and regulators and users will both find you.
Unproven. A real need and a real story, but no verifiable usage evidence of any kind. Do not let a good story stand in for evidence — health-data trust is bought with independent review. Check back in three months against ratings, reviews, and methodology disclosure.
