reThrive: Discover your True Age

Your true age is not what you think it is.

If you're tracking steps, heart rate, sleep, and workouts, you have a mountain of data. But here's the question we kept asking ourselves: Is any of this actually working?

That's why we built reThrive.

We're a two-person team, Nick and me, launching PRO today with Levers and Circles. We've been building this nights and weekends alongside an incredible reddit community that's been testing and shaping the product with us.

It means the world to me to finally launch an MVP on Product Hunt.

As a thank you to this community, we're offering:

• 50% off PRO with code PH50 and,

• 50% off Gift PRO with code PHGIFT.

There's also a free tier if you just want to check your True Age first.

What it does:

reThrive connects to your wearable and reveals:

• True Age — your biological age based on 4 biomarkers (VO2max, HRV, RHR, lean body mass)

• Pace of Aging — whether you're aging slower, faster, or on pace with time

• Levers — the 6 actions across movement, performance, and recovery that actually move the needle

• Circles — see how you compare with people like you

You get weekly updates that show your trajectory, not just snapshots.

Why it's different:

Most health apps obsess over daily metrics. But life happens. One bad night's sleep, a stressful week, a skipped workout. Day-to-day variance is huge and misleading.

reThrive focuses on weekly and monthly trends. You can't hide from your rhythms over time.

That's why we do weekly updates and weekly lever plans. Not daily guilt trips.

You see if your choices are actually working, and exactly what to focus on next.

Why I built this:

Two years ago, I was VP of Sales, new dad, classic dad bod. A body composition scale told me I was metabolically older than my chronological age. That moment changed my course.

I tracked obsessively, iterated a protocol, and reversed my biological age by 15 years. I went from couch potato to triathlete. My daughter now joins us for fun runs.

But when I tried sharing this with my wife, mom, and friends, spreadsheets felt like homework. Life always won.

People don't need more data. They need a simple framework that tells them what to focus on.

That insight helped me decide I was going to do something about it. I found Nick, a builder in the health tech space. I cold-emailed him. He said no. I kept coming back. Still no. But I didn't let go. The same persistence that helped me get healthy finally broke through. Months later, he said yes. Persistence turned a cold email into a cofounder.

reThrive is the tool I wanted for my family from day one.

We'd genuinely love your feedback, your feature requests, your honest takes.

Our reddit community has been instrumental in getting us here, and we'd love for you to join the conversation.

Drop your True Age in the comments if you try it. Nick and I are here to talk.

Thank you for the support. 🙏
