Take control of tomorrow with blēo
Longevity means an improvement in how you feel each day – more energy, more resilience, more confidence.
You are unique. Your longevity journey is personal to you.
blēo guides you through the small changes you can make today, for lasting benefits you’ll feel tomorrow.

Disease Prevention
Most chronic diseases aren’t inevitable, they’re preventable.
Research shows up to 80% of heart disease, diabetes, and other major conditions could be delayed or avoided through lifestyle changes.

Your Two Ages
A dynamic, data-driven marker of how fast (or slow) your body is actually aging.
Your biological age, unlike your date of birth, it’s something you can actively change.

Longevity 360
Sleep and stress matter - but they’re just chapters, not the whole book.
True longevity means a complete view: movement, mindset, nutrition, recovery, and resilience.

Longevity is personal
There’s not one path to health, each persons longevity is unique.
Your genetics, your habits, your environment - they all shape your journey.
How you live today shapes your tomorrow
Reframe how you think about aging – not as a passive, inevitable decline, but as a dynamic, measurable, and modifiable process.
Designed for your longevity
Two forms, one purpose.
Whether you choose the beautiful blēo ring, or the seamless blēo band, you’ll take the first step towards a better tomorrow.

Start the day right
A good night’s sleep isn’t just recovery - it’s the foundation for focus, energy, and every choice that moves you closer to the life you want.

Perfect your recovery
blēo maps your sleep cycles with clinical precision, giving you the insights you need to recover fully — because deep, restorative rest is where true health begins.

Built for real life, not perfect days
What blew me away was how naturally it fits into life. No overthinking, no tech headaches. Just steady, smart advice that builds on itself. You feel the difference before you even realize it.

100 days later, it’s just my life now
Started as a 100-day experiment. Now it’s just my lifestyle.

Not just numbers – real learning
The Longevity AI doesn’t just spit out numbers – it teaches you. Best coaching experience I’ve had, full stop.

Better nutrition without overthinking it
I’m not a ‘biohacker’ or anything – just someone who wanted to feel better. blēo helped me understand how my nutrition was holding me back, and gave me realistic ways to improve without stress. Now I sleep better, recover faster, and honestly feel lighter every day.

Looks good. Works even better.
The ring’s sleek, minimalist – exactly my style. You don’t notice it’s there. But you do notice what it’s doing for you.

Small ring, big difference
It’s not just another tracker. It’s a quiet little revolution for your health.

A short walk by the water or through the trees can reduce cortisol, rebalance your nervous system, and give your brain the break it didn’t know it needed.
