InsideTracker is the longest-running player in the category, and earned that position by getting three things right when nobody else had. They pioneered the score-based UI that turned a wall of biomarker numbers into a small set of color-coded zone scores — the visual grammar most newer trackers now borrow. They shipped the first consumer InnerAge metric, a single biological-age figure on the home screen. And they paired every flagged result with a ranked list of food, supplement, exercise, and lifestyle recommendations — the layer most newer apps are still trying to catch up to. The last disclosed funding was a $15M Series B in September 2022 led by PeakBridge.
InsideTracker is designed as a closed system, and that is a deliberate product choice. The dashboard is English-only, the testing logistics are US-focused, and the whole experience is shaped around their own Ultimate panel and the recommendation engine on top. It works well for the audience it was built for: one user, one country, one source of truth for the labs. It is a less natural fit for people who already get bloodwork elsewhere, read reports in other languages, or need one place that holds the whole family’s results.

InsideTracker sells the lab draw and the coaching layered on top. MyBloodTest tracks the bloodwork you already have — from any lab, in any language.
MyBloodTest takes a different shape.
MyBloodTest assumes you already have a way to get bloodwork — a primary-care doctor, an annual physical, an at-home kit, or a paid testing service like InsideTracker itself. Our job is to make sense of those results across time, sources, family members, and languages. There is no testing-logistics layer because we do not sell lab tests. The trade-off is real: you arrange and pay for your own draws. The upside is that everything else is free — multi-language scan, five family profiles, wearable sync (Apple Health, Health Connect, Fitbit, Withings), QR share-with-doctor links, and reference ranges from 10+ named sources including Mayo, ARUP, Quest, Labcorp, WHO, and CALIPER.
How to use both together.
If you are an active InsideTracker member, MyBloodTest works alongside it rather than against it. After each Ultimate draw is processed, save or screenshot your results from the InsideTracker dashboard, open MyBloodTest, and scan or manually enter the values. Those numbers join everything else in the timeline — older labs from previous providers, results for the rest of the family, anything you scan from a hospital portal. You keep your InnerAge score and the curated coaching on their side; MyBloodTest holds the long-running picture across every source and gives you a single QR link to share with your doctor.
