Stop managing your health.Let leto run it.
leto knows your body, your cycle and your labs. It finds what helps, builds the plan, buys what you need and books what matters. You just live.
Free on iPhone. No wearable required.
the loop
Most apps stop at the chart. leto runs the whole loop.
It watches everything, works out what it means for you, and does something about it. On repeat, quietly, in the background.
It notices.
leto watches your cycle, wearables and labs together, all the time. It catches the shift you would scroll right past.
It understands.
It connects signals a single tracker can’t. It knows what’s your cycle and what isn’t, so a bad week doesn’t become a scare.
This is your cycle, not illness. A late-luteal rise like this is normal for you. It should settle in about 3 days.
It acts.
Then it does the thing, with your ok, and tells you exactly what it did. You stay in control without doing the work.
leto never spends or books without your yes.
for everything you were told to live with
Symptoms no one explains. Guessing what’s normal. Being told it’s fine.
You’re not imagining it. I keep the record of what you feel, connect it to what’s happening in your body, and help you act on it, even the things others wave off.
your full picture
leto sees what no single app can.
Your cycle, your wearables, your labs, and how you actually eat, move and sleep. leto reads them together, so what it tells you is about you, not averages.
Apple Health & Oura — sleep, HRV, resting heart rate, every day
Your bloodwork — the markers that actually matter for you
Your cycle — exactly where you are, and what’s coming
Food, training & mood — logged in seconds, or just spoken
no wearable needed
A 30-second look reads more than you’d think.
Hold your camera at arm’s length. leto maps your face and reads your pulse and heart-rate variability from tiny colour shifts in your skin, checks your skin itself and picks up your mood, then folds it into everything else it knows. No band, no strap, no monthly fee.
what leto does
It doesn’t hand you a to-do list. It does the list.
Finds what to do
It turns everything it sees into the two or three things that actually move the needle this week. Not a feed. A plan.
Builds your food and training
Meals and workouts shaped around your cycle, your labs and what you’ll actually eat and enjoy.
Green shakshuka + ginger tea
Buys what you need
It picks the right product, checks the ingredients and the research, and orders it the moment you say yes.
Books what matters
It finds the coach, the class or the test, fits it to your week, and puts it on your calendar.
Every action needs your yes. leto never spends or books on its own.
trust you can see
leto shows its work. Every time.
It never just tells you what to do. It shows you what it saw, and why, with the source it read. You can always check the reasoning, and nothing happens until you say so.
a friend who has already done the reading
Small steps, in the right order, kept up.
leto carries the load so your health stops being one more thing to manage. Six weeks of the right small moves, and you could feel like a different person. That is the whole point.
