Morning read

Built for strength today

Testosterone is 9% above your usual and cortisol peaked right after waking. That mix favours lifting: go heavy today and keep cardio easy.

A read takes under a minute

Three hormones. Twice a day.

Your levels are not a fixed number. They swing through the day, and the swing is the part worth seeing.

  • Testosterone

    Drive, strength and motivation. It runs high early and drifts down through the day.

  • Cortisol

    Your stress hormone. It should spike after you wake and fall away by night. A flat day is the thing to watch.

  • Melatonin

    The sleep hormone. Near zero while you are up, climbing a couple of hours before bed.

One reading is a number. Two readings are a direction: the size of the swing between them is what tells you how you are actually doing.

A strong wake-up signal

Cortisol is up 4× since last night’s read, and testosterone is 9% above your usual. A good morning for heavy training or hard thinking.

Why it is different

As often as a wearable. As real as a blood test.

Many hormones move by the hour and by the day. One tool watches you constantly but never sees them; the other sees them properly, twice a year.

Ring or watch

Your wearable

It never sees a hormone. It estimates a score from heart rate, movement and skin.

How it works

Questions

Everything you might be wondering.

Is this a medical test?

No. OM is a wellness product. It helps you understand everyday things like energy, recovery and sleep. It does not detect or diagnose disease.

What does Vitali-T measure?

Testosterone, cortisol and melatonin, from a saliva swab. Together they explain your drive, your stress and recovery, and your sleep.

How often do I use it?

Up to twice a day. One read gives you a number; a pair gives you the swing between them, which is where most of the signal is.

How is this different from my watch or ring?

A wearable guesses from your heart rate and movement. OM reads the hormones themselves, so it stands on its own. If you already wear one, OM adds the why behind its scores.

How accurate is it?

Our sensor was published in npj Biosensing, a Nature Portfolio journal, and read saliva about as well as a gold-standard lab test. Clinical studies are validating the core sensing technology.

When can I get one?

Vitali-T ships in 2027. Take the free quiz and you will be first to know.

Will there be other cartridges?

Yes. The reader stays the same and you add cartridges. Cognitive Fitness and Meridian are planned for 2028, with more after that.

What does it cost?

Pricing will be announced closer to launch.
