Today’s insights

Your environment and social connections are carrying strong momentum today, but fitness is creating a meaningful drag on your overall picture.

Built on Claude· Works with your Garmin or Apple Watch· No new device· Quick & easy setup· Deterministic score, no AI guesswork· Your apps measure. None interpret.
The problem

Your health data lives in multiple apps. None of them talks to each other.

You measure everything and understand nothing. One app has your HRV, another your macros, another your runs. Every app measures. None interpret. And none cross-reference, which is exactly where the real signal is.

The solution

One score.
Five things that will help you live longer and better.

Topsy pulls five data streams into a single daily Longevity Index - then explains what to actually do about it.

From your watch

Recovery

HRV, sleep, resting heart rate and stress — how well you bounce back.

Built in logger

Nutrition

Log a meal in one sentence, audio or a photo. That's it.

10-sec check-in

Social

The one thing every tracker ignores — and science ranks near the top.

Location

Environment

Air quality, UV and green space — the context behind every number.

From your watch

Fitness

VO₂ max, activity and training load — how strong your engine is.

Your whole health, finally connected.

Resting heart rate
42Good
Resting heart rate
42Red flag

Your "normal" isn't everyone's normal.

A resting heart rate of 42 is a red flag for one person and an athlete's heart for another. Trackers that benchmark you against a population average don't know the difference. In your first week, Topsy learns your baseline — then reads every signal against your rolling normal, not a stranger's.

The score is algorithmic and deterministic — the same inputs always produce the same score. AI never invents your number. It interprets it, connects the dots, and tells you what to change.

It doesn't wait
for you to ask.

Most health apps are dashboards. They sit there until you open them. Topsy watches your trends and comes to you.

Today’s insights

That's five nights under your baseline — 5h50m vs your usual 7h10m. Recovery dips before you feel it. Aim for an earlier night; I'll check in tomorrow.

Slept badly five nights running?

Topsy flags it before you feel it — and tells you exactly how to recover.

Today’s insights

HRV is 22% below baseline this morning — despite a full night's sleep. That pattern sometimes comes before a bug. Feeling okay, or coming down with something?

HRV suddenly off after a full night's sleep?

It checks in: feeling okay, or coming down with something?

Today’s insights

Recovery has climbed seven days straight and your resting heart rate is down 4 bpm — your body's responding to the earlier bedtimes. Whatever you changed, keep it. This is exactly what building longevity looks like.

Trending in the right direction?

It tells you what's working, so you keep doing it.

And when you do have a question — just ask.

Chat is one way in. Most of the time, Topsy reaches out first.

A day with Topsy.

Your today’s
longevity index
88

Morning

Your Longevity Index and five pillar cards, with a plain-language read on where you actually stand today.

Midday

Log lunch with a photo or one line. Scored in seconds.

Today’s insights

Air quality near you just hit 156 AQI — unhealthy for a hard effort outdoors. Your lungs would take the hit, not your legs. Move today's tempo indoors, or swap it for an easy recovery walk.

Afternoon

A nudge: your air quality is poor today — keep the hard session indoors

Evening

Evening — A weekly social check-in, 10 seconds. The pillar no one else measures.

Getting started

Up and running in two minutes.

No setup marathon, no manual data entry, no new device to buy.

We're not chasing a number
We're trying to be there.

Our goal is simple: help you add the good years

We're two fathers who got obsessed with our health for a reason that has nothing to do with leaderboards. Longevity isn't a vanity score — it's being around, and healthy, for the people who need us. Long enough to see our kids and grandkids grow up.

We learned the hard way that collecting data is the easy part — a wristband wakes you up. The hard part is "so what now?" Every app we tried could measure. None could answer that question. So we built the coach we wished we'd had: one that reads everything together, knows our normal, and actually tells us what to do.

Founder

Five years ago I was 20 kg heavier, stressed, and running on empty. A $20 wristband I got as a gift showed me numbers I couldn't ignore. Today I run a half-marathon under 1:50, my blood pressure is normal, and the weight is gone. Along the way I built my own longevity index out of Garmin data — because the watch alone was never enough. Topsy is that index, grown up.

When Mirko showed me his index, I saw the same thing I'd seen building digital products for the past decade: great data is worthless if people can't feel it or act on it. My job is to make Topsy something you actually want to open — clear, human, and honest about your body.

How we calculate your daily normal

Topsy weights five biological and behavioral pillars using deterministic algorithms. We cross-reference wearable data with active check-ins to build a rolling baseline that is unique to you.

FAQ

Questions people
ask the most

Yes. Topsy is built for people who already track — Fitness and Recovery, half of your score, come straight from your Garmin or Apple Watch. Without a wearable there's no biometric signal to read, and we'd rather tell you that than give you a hollow score. Garmin and Apple Watch today; more devices coming.

No. The core of Topsy is a deterministic scoring engine — the same inputs always produce the same score, and AI never invents your number. AI does what it's actually good at: reading your whole picture, connecting the dots, and telling you what to do about it in plain language. And most of the time you don't ask — Topsy notices a trend and comes to you first.

Your watch scores what your watch can see. It doesn't know what you ate, how connected you felt this week, or that the air outside is at 156 AQI. Topsy reads all five pillars together — and against your baseline, not a population chart. The signal isn't in any single metric; it's in the cross-reference.

Never. Your Longevity Index is algorithmic and deterministic — auditable, repeatable, no guesswork. AI interprets the score; it doesn't calculate it.

Two minutes of setup, then it mostly runs itself. Your watch feeds Fitness and Recovery automatically, Environment comes from your location, Social is a 10-second weekly check-in. The only daily habit is food logging — one sentence, a photo, or a voice note. If you skip a day, nothing breaks.

Yes. Type "pasulj i kupus salata" or snap a photo of your lunch — Topsy's AI parses the meal and calibrates the macros against a real food database. It was built by someone whose food logger didn't speak his cuisine, so this one does. No barcode hunting, no searching through 40 wrong entries.

Your data is yours — never sold, never shared, never used for ads. It's encrypted in transit and at rest, and you can delete your account and everything with it at any time. We're a product you pay for, not a product that sells you.

No. Topsy provides general wellness information — it helps you see trends and build habits. It doesn't diagnose, treat or prevent any condition, and it will never replace your doctor. When something looks worth a professional's eyes, Topsy says exactly that.

The first 500 members get in free — a full month at launch, no card required, plus early-member discounts after. Final pricing will land with launch, and waitlist members hear it first.
