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.
You can download the app here:

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?
Looks really cool.
I in France and it doesn't seem to be available here. Will it be anytime soon ?

@olivierbinet_code we are resolving some App Store regulations for EU - you should be able to use within 1-2 weeks.

@olivierbinet_code We are now live in your region: https://apps.apple.com/fr/app/pinnacle-upgrade-your-mind/id6498899043 . Hope you enjoy the app, let us know what you think!
Interior designer and working mum here—my life is basically a constant battle against physical and mental clutter. I’m naturally skeptical of 'performance' tools because they usually just add more noise to an already loud day.
Pinnacle feels different. From a design perspective, the spatial hierarchy and use of negative space is calming, like walking into a clean studio after a chaotic morning with the kids. Was 'mental load reduction' a core part of the brief, or did the minimalist UI just happen to solve that for us busy parents? Love using the app so far!

This is such a thoughtful observation @stef_hacking. To answer your question: Mental load reduction wasn't just part of the brief; it was the entire reason we built this.
Having spent a long time in design studios, I realised we often over-design for 'utility' and under-design for 'cognition.' We intentionally used that negative space to create 'breathing room' for your thoughts—much like a physical clean studio as you mentioned.
We wanted the AI to feel like a calm curator rather than another voice shouting for your attention. So glad to hear it’s resonating with your workflow 🙌

@enzogorlamixyz Hi Enzo, which App Store are you trying to access from? We have it in significant parts of Europe as well.
The combination of real-time physiological measurement + conversational coaching is exactly what's missing from wellness apps. Most either track passively without actionable guidance, or give generic advice without knowing your actual state.
Using iPhone's built-in sensors for HRV and stress detection is smart - removes friction that external devices create. The science-backed approach matters here since the wellness space is cluttered with pseudoscience.
Curious: how does the AI calibrate its coaching tone based on someone's stress level? Does it dial back intensity when it detects you're already overwhelmed, or push harder when you're in flow state?
This fills a real gap in the market. Current tools either focus on processing the past (therapy) or are too static and impersonal (meditation apps). Using the iPhone sensors you already have for real-time biometric reads is clever - no new hardware purchase barrier. The intersection of emotional state interpretation + practical training could create a feedback loop thats actually actionable. Question: how does the system adapt recommendations when someone is going through an unusually stressful period vs their baseline?
Using iPhone sensors for cognitive state detection is clever - leveraging existing hardware rather than requiring wearables. The positioning between therapy (expensive, backward-looking) and meditation apps (impersonal, static) hits a real gap. Curious about the sensor fusion approach - are you correlating touch patterns, typing cadence, voice analysis during conversation? The real-time adaptation based on measured state could be powerful for in-the-moment coaching.

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

@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.
