A huge thanks to everyone who tried Pinnacle, commented, challenged us, and shared thoughtful feedback last week
We were excited to finish as the #4 Product of the Day. More importantly, the launch gave us a clear signal about what resonated most.
For anyone new here: Pinnacle turns your iPhone into an AI performance coach. It uses built-in phone sensors, conversation, and wearable data via Apple Health to help you improve focus, resilience, energy, and performance with science-backed tools.

A few things that stood out:
1. People want insight, not just more data
One of the strongest themes in the comments was that raw metrics alone are not enough. People don t want another dashboard full of numbers with no context.
They want to understand:
How am I doing right now?
What is driving it?
What should I do next?
That is a big part of how we think about Pinnacle. The goal is not to flood you with biometrics. The goal is to turn signals from your body and behavior into something actionable in the moment.
2. Low-friction measurement really matters
A lot of people responded to the fact that Pinnacle works from the iPhone you already have, without requiring extra hardware to get started. That convenience matters more than we expected.
Several comments also pushed on an important challenge: accuracy and calibration. They were right to do so.
If you are using phone-based measurement, the system has to adapt to the individual, establish a baseline, and avoid overreacting to noisy signals. That reinforced one of our core beliefs: relative progress from your own baseline is more useful than generic scores.
3. Personalisation has to reflect real life
One of the most useful questions we got was whether brain-performance baselines should account for hormonal cycles. The answer is yes.
If you want to understand focus, energy, and resilience properly, context matters.
Personalisation cannot stop at a single static baseline. It needs to reflect the realities of each user s life, including sleep disruption, parenting, pregnancy, postpartum recovery, and cycle-related changes over time.
This is an area we want to keep improving.
4. Coaching works best when it is personalised to state, not just prompts
Another theme was the difference between Pinnacle and a standard LLM.
People have already tried using general AI as a coach, and the common experience is that it still puts too much burden on the user to know what to ask.
What we are building is different: Pinnacle combines conversation with biometric and behavioral context, then guides the right intervention at the right moment.
That might mean breathwork, reflection, a micro-break, or a focused coaching prompt depending on what the system sees.
5. Trust, privacy, and product feel are part of the product
Some of the best questions were about privacy, camera use, and whether the experience feels helpful rather than intrusive.
Those are not side questions. They are central.
We want Pinnacle to feel like a calm, intelligent coach, not another noisy app demanding attention. That means being thoughtful about privacy, clear about how sensing works, and careful about when the product should guide versus when it should get out of the way.
What we re doubling down on now
Better baseline calibration and more personalised scoring
Stronger coaching flows based on both conversation and biometric context
Continued work on attention measurement and training
Better support for more diverse stress and recovery patterns across users
Making the product feel lighter, clearer, and more useful from day one
Launch day was great, but the real value has been seeing which parts of the vision people immediately understood, and which parts we need to explain better.
If you have tried it already, I d love to hear: what clicked for you, and what still feels unclear?
Hey @joel_jackson1 first of congratulations on the launch, I just check Pinnacle and it seems solid but I was wondering what's different in it that others don't have?
I mean that solution are you guys providing that existing platforms are not solving? Would love to hear your feedback and best of luck!
the 'performance coach' framing is interesting vs the usual wellness/health angle. feels less guilty more ambitious. does it adapt based on what you actually do or is it mostly static recommendations
Nice feature@joel_jackson1 , but which iPhone sensors are you actually using to infer HRV and stress?
Used pinnacle for a few months as a beta tester - and it was really great! Good synthesis of different signals, really nice goal tracking, all backed up with accountability via coaching. Still sustaining habits we worked on months ago!
This was what I wanted to build for my openclaw as a skill from Apple Health input.
The flow and step by step instruction is very detailed.
1 problem I encountered is that the LLM change language during conversation for no reason.
Add ifttt or more language.md for user preference

Sounds simple, but my eyes by default feel "tired" how does Pinnacle adapt to understand that's my normal eye expression? Congrats on the launch!
