Collect your sample
Place the saliva strip in your mouth for 60 seconds, then pull it back through the cassette. The sample seals inside — and the reaction begins.
Know your free
testosterone.
See what
actually moves it.
The at-home free-T monitor for men who want to see the change. No blood draw. No waiting. Results in 20 minutes — built to track the trend, not just one number.
How it works
From sample to insight in 20 minutes.
No needle, no clinic, no five-day wait. Three steps, the same controlled measurement every time.
Insert for analysis
Slide the cassette into the Olo reader. A dedicated fluorescent system measures the sample at lab-grade accuracy — the same controlled environment, every time.
Read your trend
Your free-T result lands in the app and joins your trend line. Olo prompts you to test at a consistent time each day, so every point is comparable — and the line you see is signal, not the daily swing.
Why testosterone
You track everything. Except the hormone that drives all of it.
You track HRV, sleep and training — but the hormone sitting under all of it has been a black box. Olo measures free testosterone repeatedly, so you first see your baseline, then watch it shift when you change your training, your sleep, or your TRT protocol. Not one number. A trend you can act on.
- Free testosterone trend line — see the direction, not just one number
- Correlate results with sleep, training, treatments, alcohol, stress etc.
- Track what actually moved your testosterone this week
- Build a data-driven personal protocol over time
Technology
Two components. One precise measurement.
The cassette
Saliva collection + fluorescent strip
Single-use. Integrated saliva collection strip that loads directly into the cassette housing. Fluorescent lateral flow immunoassay begins the moment your sample is sealed inside.
The reader
Lab-grade fluorescent reader
Olo uses a dedicated fluorescent reader. The same controlled measurement environment, every single time — because a trend is only as trustworthy as the consistency behind each reading. Olo users demand accuracy. And accuracy can only be achieved with a dedicated reader. Compact, rechargeable, reusable. Connects to the Olo app via Bluetooth / Wifi.
The team
Deep roots in science. Built to ship.
Olo team consists of researchers and engineers with long backgrounds in biotech and diagnostics — people who have spent careers turning laboratory science into tools that actually work in the real world.
Etvi Juntunen
CEO & Co-founder
Etvi's career has been defined by one pursuit: turning rigorous biotechnology research into health solutions that make a real difference. With a background in diagnostics and lateral flow immunoassay development, he has published research on fluorescent nanoparticle-based detection systems — the exact technology at the core of Olo.
His driving conviction is that scientific breakthroughs only matter when they reach the people who need them.
Why Olo
Built for repeat use.
Built for real data.
Most doctors test total testosterone. Free T is the fraction your body can actually use — and it’s what moves first when you change something. Olo measures the bioactive fraction from the start.
Saliva naturally reflects free testosterone — unbound hormones cross into saliva; protein-bound testosterone does not. No needle. No five-day wait. Just objective, repeatable data you can act on.
A single measurement — blood or saliva — is a snapshot, and a noisy one: testosterone swings by the hour and the day. Ten standardized measurements over three months, correlated with your lifestyle and your protocol, is signal. Olo is built for the trend, because the trend is where the truth is.
A blood test costs $70–300 and gives you one number. Mail-in saliva takes five days — for one number. Neither shows you a trend you can act on. Olo gives you a lab-grade free-T result in 20 minutes, at a fraction of the cost — and it’s built to be repeated, so you see the line, not just a dot.
The reader handles all measurement. Your phone is only the display. Identical precision on any device, in any lighting, every time.
Objective, repeatable data you — and your clinician — can both trust. Your number, your trend, and the context that explains it.
We exist to make testosterone visible — and actionable.
Men optimize everything: sleep, training, nutrition, recovery. But the hormone that determines how their body actually responds to all of it has remained invisible. Olo changes that.
About Olo
We exist to make testosterone visible — and actionable.
Men optimize everything: sleep, training, nutrition, recovery. But the hormone that determines how their body actually responds to all of it has remained invisible.
Olo changes that.
The problem
The most important number you've never tracked
You've been tracking your HRV, sleep stages, and training load for years. But free testosterone — the hormone that sits beneath every one of those metrics — has never been part of the picture.
A clinic test is expensive, infrequent, and gives you total testosterone. A single number, once a year, with no context. That's not data. That's a snapshot. And a snapshot doesn't tell you what moved it.
The solution
Continuous tracking, at home, at pg/mL precision
Olo is built around one insight: free testosterone can be measured accurately from saliva — without a needle, a clinic, or a prescription. All it takes is the right hardware.
A dedicated fluorescent reader replaces the lab bench. A single-use cassette handles the test. And the app turns repeated measurements into the pattern data that actually means something.
Built on three principles
1.
Measure the right thing
Total testosterone is what most doctors test. Free testosterone — the bioactive fraction your body can actually use — is what determines how you feel and perform. Olo measures free T from the start.
2.
Repeat is everything
A single measurement is a starting point. Ten measurements over three months — correlated with your sleep, training, alcohol, and stress — is intelligence. Olo is designed to be used repeatedly.
3.
No agenda but yours
Objective, repeatable data you — and your clinician — can both trust. Your number, your trend, and the context that explains it.
Say hello.
We'd love to hear from you — whether you're curious about the science, interested in partnering, or just want to follow the journey.
