Hey everyone! We re the team behind Pinnacle, and tomorrow we are finally launching on Product Hunt.
We started this journey because most 'high performance' tools are just trackers digital chores that tell you what happened to your body, but don't help you understand your mind. We wanted to build a system that helps you maintain focus, resilience, and energy when the stakes are high.
What we've been building: We ve moved beyond simple chatbots to create an AI agent that uses built-in iPhone sensors like HRV (Heart Rate Variability) and voice-based reflection to turn mental signals into actionable clarity. No 'workslop,' just science-backed tools for situational execution.
We would love your support and feedback when we hit the feed tomorrow
Calibrating to a personal baseline is a good design decision. I've used apps that tell me my focus score is "72" with no context for whether that's good or bad for me specifically. Relative improvement from my own starting point is a much more useful signal.
How are you using the iPhone sensors for brain measurement? I'm curious whether it's HRV-based (which correlates with cognitive readiness) or something else. And do the breathwork exercises adapt based on what the sensors detect, or is the exercise library more of a fixed menu that you recommend from?

Huge fan of Pinnacle. Genuinely one of the best UXs I’ve seen

@tanaykothari massively appreciate the support through this journey!

@tanaykothari Thank you Tanay. We pay very close attention to making the experience as slick as possible, smoothing down friction wherever we can. I think it pays off in the various different interactions across the app.
So it's like Whoop for the brain? Love the idea. This will go big. Turn your phone from brain rot to brain healer. Good luck team!

@davitausberlin I've always wanted to call it "Whoop for the mind", which it is except we don't require a hardware device strapped to your head. I think it's more "Runna for the mind"!
Pinnacle
Cheers @davitausberlin. Yes that's exactly the spirit of what we were going for! Much appreciated 🙏

Cheers@kevinbensmith! It's great to have people trying out the app 🙌

@kevinbensmith thank you!
Congrats on the launch, Joel! Really impressive to see how you're leveraging on-device sensors for these kinds of emotional insights. The focus on performance and resilience for knowledge workers hits home.
Quick question: what sensors on the device are you using?
Would love to see how this evolves. Upvoted!
I've been tracking HRV with a chest strap for a while and the data is genuinely useful, but iPhone sensor accuracy for HRV is... mixed at best.
Is the "performance score" heavily weighted on HRV, or is it more of a composite that uses conversational inputs + biometrics together so that noisy sensor data doesn't throw off the whole picture?
Interesting concept. Turning a phone into a tool that helps people understand their mental state throughout the day sounds powerful. I like the idea of combining biometrics with simple, actionable insights instead of just raw data. Which iPhone sensors does Pinnacle rely on to interpret emotional state and focus levels?
