The problem
Lab results trapped in clunky patient portals that weren't built for tracking trends over time
No way to connect biomarker changes to the lifestyle factors — supplements, diet, exercise — that caused them
You're spending hundreds on quarterly labs but can't tell if your interventions are actually working
OutLast logs every biomarker alongside your daily habits — so you can see exactly what's moving your numbers in the right direction
How it works
When your blood work comes back, log each biomarker with one tap. Testosterone, vitamin D, HbA1c, lipids, thyroid — capture the numbers that matter without wrestling with a spreadsheet.
Log the supplements you start, the diet changes you make, the workouts you add. When your next labs come back, you’ll know exactly what changed and why.
Compare results across quarters. See your vitamin D climb after adding D3, your HbA1c drop after cutting sugar, your testosterone improve with better sleep. Your health story, told in data.
What you get
Track testosterone, vitamin D, HbA1c, cholesterol, thyroid, iron, inflammation markers, and any other lab result. Your complete blood work history in one place.
Compare biomarker values across quarterly tests. Spot improvements, catch declining markers early, and understand how your numbers change over months and years.
Log supplements, diet changes, and lifestyle interventions alongside your blood work. See the clear connection between what you do daily and what shows up in your labs.
Build streaks around quarterly testing. Never let six months slip by without labs again. OutLast keeps you accountable to the testing cadence that optimizers swear by.
The science
What people say
“I’ve been getting quarterly blood work for two years but never had a good way to track trends. OutLast lets me see my testosterone and vitamin D climbing over time — it’s incredibly motivating.”
“My doctor told me to raise my vitamin D. I started supplementing D3 and logged it in OutLast. Three months later, my levels went from 32 to 55. Having everything in one place made the connection obvious.”
“I used to screenshot my lab results and forget about them. Now I log every marker in OutLast alongside my supplements and diet changes. It’s the simplest way to actually use your blood work data.”
