Hi Product Hunt, I'm Patrick, founder of Jumel Systems. 👋

Our company line is "We make invisible systems visible." Your metabolism is one of the most invisible systems you have.

You eat lunch, and two hours later you're either sharp or sinking. Calorie counters tell you what you ate. They don't show what it may do to you.

So I built MetLens, our first product.

HOW IT WORKS

1. Build your profile: a few quick questions so the simulation reflects you.

2. Type or photograph a meal: MetLens breaks it down into macros, fiber and other components.

3. See the simulation: a forecast of how that meal may move your glucose, insulin and energy over the next few hours, before you take the first bite.

No wearable. No lab test. It uses Google Gemini to generate the simulation.

TRY THIS

Simulate your usual breakfast, then a different one, and compare the curves. That's the quickest way to see what MetLens does.

WHAT YOU GET

Free: 5 simulations a month, a glucose chart, meal text input and a fasting tracker.

Pro ($9/month or $79/year): the What-If simulator and scenario modelling, an AI meal planner and Smart Chef, lifestyle and future-self projections, and unlimited AI coaching.

WHAT IT IS NOT

MetLens is educational. The results are AI-generated simulations, not medical advice, a diagnosis or a measurement, and not a replacement for a CGM. Use it to learn, and to start better conversations with your doctor.

ABOUT ME

I'm building MetLens solo, so I read and reply to every comment today. Your feedback shapes what comes next.

I'd love your honest thoughts on:

1. Is the sign-up and profile setup too long?

2. Does the "educational, not medical advice" wording feel right?

3. Which simulation did you try first, and was anything confusing?

4. What would make you come back to it?

Available in the US, Canada, UK, EU, Australia and South Africa.
