Decode vs InsideTracker
Both will read a blood test you already have. They disagree about where the target comes from. InsideTracker scores your blood, DNA and tracker data against its own model and returns ten scores out of 100 — $149 a year for the platform, plus $340 and up per test. Decode gives you no score. It puts each result next to a number a physician put on the record, links you to the second they said it, and checks your supplements against it, for $12.99 a month.

| Decode | InsideTracker | |
|---|---|---|
| What it is | An iPhone app that reads bloodwork you already have | A platform that scores blood, DNA and tracker data together |
| Price | $12.99 a month or $79.99 a year, 7-day free trial | $149 a year membership, plus $340+ per test |
| Reading labs you already have | Included. Photo, PDF or Apple Health, any lab | Included in the membership; also sold as a $119 plan, up to 43 biomarkers |
| Blood draw | None. Bring the report you already have | In-lab, or a mobile phlebotomist for $119 more |
| Where “optimal” comes from | Not ours to set. A physician or research scientist put the number on the record, and you can watch them do it and judge the reasoning yourself | InsideTracker’s own zones, set by age, sex and activity |
| What you get back | Each number against the stated line, plus the quote and the video | Ten healthspan scores out of 100 and a customisable action plan |
| Supplement label scanning | Point the camera at the label, get a pass, weak or skip at your numbers | Not offered. Supplements appear as recommendations |
| Asking a follow-up question | Ask a follow-up on any result or supplement and see who said the answer, on video, from the moment they said it. When nobody has, the answer says so | Recommendations delivered in the app rather than a chat thread |
| DNA and wearables | Neither. Blood, age and sex only | DNA Kit $249; fitness tracker data folded in |
| Biological age | Not offered | InnerAge 2.0, a $99 upgrade or $249 alone |
Decode is an iPhone app launching soon — the app-side rows describe what ships at launch. InsideTracker figures are the list prices in its own Shopify store on 11 August 2026; test prices vary by variant and add-on, and a mobile draw is required in New York, New Jersey, Rhode Island, Hawaii and Arizona. Check their store before you buy.
What InsideTracker does that Decode doesn’t
- Orders the blood test, in a lab or at your door
- Folds in DNA and fitness tracker data alongside blood
- Ten healthspan scores out of 100, tracked over time
- A biological age figure through InnerAge 2.0
- Fifteen years of performance-focused product behind it
What Decode does that InsideTracker doesn’t
- Names the physician behind every optimal number, and links the video
- Scans a supplement label and grades it against your own numbers
- Says out loud when nobody has stated a number for a biomarker
- Shows the person and the moment behind every follow-up answer
- Charges one flat subscription, with no test or kit to buy on top
- Sells no supplements and takes no affiliate money
Which one should you pick?
- Pick InsideTracker if you want a score to train against.
- You lift or run seriously, you already wear a tracker, and one blended number per system is how you like to measure progress. The DNA and wearable layers are things Decode does not do at all.
- Pick Decode if you want to know who decided what “good” is.
- You have results in your hand, you have been told they are normal, and you want to see the actual bar a physician named — and check the four supplements you take against your own numbers. $12.99 a month, no test to buy.
- Watch the total, not the headline price.
- A first year of InsideTracker with the membership and one Ultimate test lands around $489 at list, before a DNA kit or a mobile draw. Decode is $79.99 a year and does not sell you a draw. They are not the same purchase.
InsideTracker already reads labs you bring it
Since 2009, and it does one thing Decode does not attempt: it pulls blood, DNA and your watch into a single model and hands back one number per system. If you train seriously and you want a score to chase quarter over quarter, that is a real product and Decode is not a substitute for it.
It also already does the thing people assume only Decode does. Uploading a test your own doctor ran is part of the $149 membership, and InsideTracker’s store lists a standalone Blood Results Upload plan at $119 that analyses up to 43 biomarkers from a test your doctor, employer or insurer ordered. So “reads labs you already have” is not the difference between these two.
A model computes their number. The one we show was said out loud, on the record.
An optimal zone is a claim about your body, and every product on this page makes one. InsideTracker computes yours from its own model, adjusted for age, sex and how much you train. That is a defensible way to do it, and it is also a number you cannot audit: there is nobody to look up and nothing to watch.
Which is not an oversight on their part. The zones are the product — the $149 a year buys access to them, so they have to be InsideTracker's. Sourcing them to physicians outside the company would hand away the thing being sold. Decode charges for neither the test nor the range, so pointing at other people's numbers costs it nothing.
Decode refuses to set a number at all. A threshold appears in the app only when a physician or research scientist has stated it, figure included, on video you can open. Vitamin D is the clearest case: almost every lab in America prints the same range, and almost nobody flags anything inside it.
Your lab starts “normal” at 30. The stated optimal starts at 40.
“Most people can take a supplement in the range of 2,000 to 4,000 IUs a day depending where your blood levels are at and keep keep their vitamin D levels within that, you know, 40 to 60 range.”
A vitamin D of 32 ng/mL comes back clean on every report in the country. It also sits eight below the floor in that sentence. Decode draws both lines, names the person, and links to the second the words were said, so you can check whether we quoted fairly. See the full page on optimal vitamin D levels.
Patrick is one of fourteen physicians and research scientists with numbers on the record in Decode. A few of the others, and where each drew their line:
- Dr. Peter Attia, M.D.ApoB · under 60 mg/dL36:30 →
- Dr. Robert Lustig, M.D.Uric acid · under 5 mg/dL21:19 →
- Dr. Mark Hyman, M.D.GGT · under 20 U/L23:47 →
- Dr. Rangan ChatterjeeHbA1c · under 5.4%1:52:35 →
A model always returns something. Decode sometimes can’t.
A stated range exists for 25 of the 98 biomarkers Decode covers, held up by 57 quotes with video links. For the other 73, nobody we cite has named a number, so the lab’s own range is the only line drawn and the page tells you that is the situation. Browse them all at all biomarkers.
Common questions
How much does InsideTracker cost in 2026?
The membership is $149 a year and renews annually at full price. Tests are bought on top: the Ultimate blood test is listed at $340 for members, and the Foundation test starts at $199. A DNA Kit is $249, InnerAge 2.0 is a $99 upgrade or $249 on its own, and a mobile blood draw adds $119. Verified in InsideTracker’s own store on 11 August 2026.
Does InsideTracker let you upload blood results you already have?
Yes. The $149 membership includes the ability to upload past blood results, and the store also lists a standalone Blood Results Upload plan at $119 that analyses up to 43 biomarkers from a test your doctor, employer or insurer ran.
What is the difference between Decode and InsideTracker?
InsideTracker scores your blood, DNA and tracker data against its own model and returns ten healthspan scores out of 100 with food, supplement and lifestyle recommendations. Decode does not score you. It puts each result next to a number a named physician or research scientist stated on the record, links to the second they said it, and checks the supplements you already take against your numbers.
How much does Decode cost?
$12.99 a month or $79.99 a year, with a 7-day free trial. There is no test to buy, no membership fee on top, and no DNA kit.
Which is better for athletes?
InsideTracker has been built around performance since 2009 and combines blood with DNA and wearable data, which is a genuine advantage if you train seriously and want one score to follow. Decode is narrower: it reads bloodwork and grades supplements, and it does not read your watch.
Does Decode need a DNA test or a wearable?
No. Decode needs a blood test result plus your age and sex. Nothing else. Add the report as a photo, a PDF, or from Apple Health.
Does Decode recommend supplements to buy?
Decode tells you whether a supplement you already own holds up at your numbers — a pass, a weak, or a skip — and why. It sells no supplements and takes no affiliate money, so nothing it says is shaped by what it earns.
Does Decode diagnose or give medical advice?
No. Decode reports what named physicians and research scientists have said on the record and puts your number next to theirs. It is educational, not medical advice. Talk to your doctor before you change anything.
