Heaven Health vs Function Health: which AI longevity coach is right for you?
Updated 3 October 2026 — for the live, daily re-checked scorecard see the comparison at the top of our homepage.
Function Health is $365 a year for 160+ lab tests a year, with clinicians reviewing every result, in the United States. Heaven Health is a free daily wellness app with an AI coach. They are different shaped products — here is the honest read on which one you want, and when both make sense.
The 5-second answer
Choose Function Health if you live in the United States and want real lab testing — 160+ tests a year — with clinicians reviewing your results, for $365 a year. On labs and clinical oversight it is clearly ahead of us. Choose Heaven Health if you want a free daily routine — a morning ritual, a daily Heaven Score, scheduled fitness classes and an AI coach — and you already get blood tests some other way. If you can afford both, they layer well: Function Health for the labs, Heaven Health for the days in between.

Where Function Health wins
Function Health has the physical pipeline. Membership includes 160+ lab tests a year through partner labs across the United States — thyroid, hormones, advanced lipids, heavy metals, inflammatory markers, vitamins and minerals. That is real venepuncture and real lab results, and clinicians review every result. Heaven Health does not draw blood and has no clinician review. If you want bloodwork done for you on a schedule, with the logistics handled and a clinician looking at the numbers, Function Health is genuinely better at that part of the job.
Function Health also matches us on things we used to claim as ours. It has a Private AI Chat (our scorecard still counts Luna's spoken replies as a lead over a text-only chat), it accepts uploads of your past results from other labs, it says its guidance is grounded in peer-reviewed studies, and it runs on iOS, Android and the web. Mark Hyman MD is a co-founder, which matters if you prefer a recognisable physician name on the door. Heaven Health is software-first: we do not have an in-house clinician, we do not diagnose and we do not prescribe.
On price, $365 a year for 160+ lab tests is strong value for anyone in the US who would otherwise pay for those panels separately. If you live in one of the 48 states it serves and lab testing is what you need, it is hard to beat.
Where Heaven Health wins
Heaven Health is built around the day, not the draw. Every morning Luna runs a 60-second ritual — you can talk and she listens (on Android now; on iPhone with the next update) — and turns how you slept, how your energy feels and what is on your mind into a daily plan with a Heaven Score on top. Outside the ritual, Luna is a text chat that can speak her replies. Function Health has no daily score that we could find, no morning ritual, no food scanning and no guided fitness classes. Heaven Health has a barcode food scanner (meal-photo scanning is paused until it is reliable) and scheduled fitness classes every three hours (on Android now; on iPhone with the next update).
The second difference is the research feed. Luna's research team reviews new published research every day and turns relevant findings into plain-English protocols that cite their sources. Function Health's guidance is grounded in peer-reviewed studies too, so this is a difference in cadence — a daily feed — rather than a claim that they ignore the science.
Price is the third honest difference. Heaven Health's core app is free. Some features use tokens, which you can earn by watching ads or buy from $0.99 — reading a blood test, for example, costs 25 tokens. Function Health is $365 a year, which buys real lab tests; Heaven Health does not include any. If you are outside the United States, Function Health is not available to you at all, while Heaven Health is on the App Store and Google Play.
To be clear about where we are today: Heaven Health runs on iPhone and Android. The public iPhone App Store build is v3.6.0 (5 May 2026) and is in English; the Android build on Google Play is v3.7.4 (2 September 2026). The app is being localised into more languages, rolling out with the next iPhone update.
The case for using both
For US-based users with the budget, the two products layer well. Function Health handles the physical bloodwork and the clinician review — something no consumer app can replicate. You can then upload the PDF or a photo of the results to Heaven Health. Our parser reads the markers (25 tokens per read), Luna explains them in plain English, and they feed into your daily plan and Heaven Score.
Function Health gives you the data and the clinical eyes on it; Heaven Health gives you a daily routine that tries to turn the data into habits. The Heaven Health core app is free, so adding it on top of a Function Health membership costs little beyond the tokens for each blood-test read.
The case for switching
Heaven Health may suit you better if you live outside the United States, where Function Health is not available; if you already get blood tests through your GP, a private clinic or an employer programme and want a daily routine on top rather than another lab membership; or if you want a daily check-in rather than results a few times a year. If you need a blood test, Heaven Health can help you book a verified third-party testing centre — you pay the centre directly.
Do not switch from Function Health if you need the lab testing and have no other way to get it — Heaven Health does not include blood tests. Do not switch if clinician review of your results matters to you; Heaven Health has none. We are a software wellness app, not a clinic. For diagnosis or treatment of any condition, see a licensed healthcare professional regardless of which app you use.
