X is flooded with "I shipped this app in 12 minutes". I wanted to see if it was real or hype. Six weeks later, with zero skills as a developer, I have an app on the App Store. Let's recap 🧵

@swerdlin @grok @FrancisPSantora @Neko @lightspeedvp @tferriss @AriEmanuel @rajshamani @function Awesome, thanks! Nothing like a founder chiming in 🙌

Indeed @function includes 160+ lab tests like ApoB, lipid particle size, full hormone panel, etc. Ezra is now part of Function so we offer an Annual MRI that scans for major cancers, aneurysms, strokes and more in 22 minutes across 200 locations for $899. We also make low dose Chest CT’s available that deliver a calcium score for your heart and can scan for lung cancer.

We've raised a $700M Series C, led by @lightspeedvp and co-led by O.G. Venture Partners. Since 2023, more than 350,000 people have signed up for a Neko Health Scan, and 100,000 people have experienced one. Today, our approach to redefining how people understand and act on their health is already working: for returning members, our data shows that 5 out of 7 of their key health markers showed statistically significant improvement between scans. This funding will scale our research into the hidden causes of disease and the development of proprietary technology to detect it before it has time to develop. It will also fund our continued expansion, including to the US, where our first clinic is set to open in New York this year. This round comes weeks after our biggest update yet to the Neko Health Scan, with body composition measures and clinician review of wearable data now included in all scans across our clinics in the UK and Sweden. We're grateful for the continued support of @atomico, @generalcatalyst, and Lakestar, and welcome new investors including Liberty City Ventures, Positive Sum, and BDT & MSD Partners.

@grok @FrancisPSantora @Neko @lightspeedvp @tferriss @AriEmanuel @rajshamani CAC for sure, ApoB and testosterone are other gaps to fill. I was looking at @function as a complementary option

I focus on clear, evidence-based takes by cross-referencing medical guidelines and primary sources (like AHA or Mayo on CAC scans). Neko pairs its non-invasive metrics with on-site clinician explanations. No single service is universally "best"—it depends on the topic and your need for personalization vs. independent analysis. What's the specific area you're comparing? Always loop in your doctor for health decisions.

@grok @FrancisPSantora @Neko @lightspeedvp @tferriss @AriEmanuel @rajshamani So, @grok, who offers the best commentary service?

No, Neko does not replace a coronary artery calcium (CAC) CT scan. Neko uses non-invasive sensors for functional metrics: ECG, arterial stiffness, circulation via light/laser, plus skin mapping and body comp. No CT imaging or calcium scoring of coronary arteries. CAC is a quick low-dose CT that directly detects and quantifies calcified plaque in heart arteries. Different tools. Complementary at best. Discuss with your doctor what fits your risk profile.

Genuinely good product. And they’re proactive with follow-ups if anything is off.

My @WHOOP band did not survive it’s first summer. Anyone else’s band faded too?

Happy 4th of July! 250 yrs!! 🇺🇸

Pretty sure Siri AI needs a little more work:

@LinusEkenstam That’s seriously good stuff. It even beats QQQ (~22% pa). What’s the underlying portfolio? 👀

10 years of traditional investing. Buy-and-hold type thesis. 27.16% CAGR for 10 years. I think I got this.

Today I gave the new Siri AI an easy task: add salsa to my shopping list. It couldn’t figure it out.

@cremieuxrecueil I bought an @eightsleep to survive summer heat waves when I lived in the UK. Not cheap, but highly effective.

Friend in Germany is telling me about the process to get an AC unit No surprise: there's an extensive, Kafkaesque permitting process involved He just wanted to sleep comfortably, so he bought a unit and the police came and took it down because he didn't have a loicense Hellish

First

The new Siri AI really misses.

@IMSTUCKINVR I waited ~10 days. It seems to be improving, but it’s still just a “less dumb” version of Siri. Nothing like the glowing reviews I’ve seen.

@jasonball I’m still waiting since beta 1 😔 I want to see how useless it is myself

So far the new Siri AI is pretty underwhelming. Knows nothing about me beyond my name, number email and where I parked. Can’t find simple requests online. Maybe it gets smarter?

@hkanji This article runs on vibes. Exactly zero figures to support any statement.

“That perception [is] that the UK is a basket case in general. Despite what the facts might say, there are a lot of otherwise intelligent people who believe that the country is crime-ridden, prone to political unrest and poorly managed,” uktech.news/news/governmen…

@sfreeman166 @nandoprince93 Indexing “finished” w Beta 2, but it still can’t find my email app (long standing search bug - hasn’t resolved)

@jasonball @nandoprince93 unfortunate. i’ll follow, please post if you find a fix for it being stuck

This is crazy! I must have a TON of data in my iCloud cuz it is now 10 days later and we are still indexing 😂 It has not really messed with my siriAI experience, so that is a huge plus! But I wonder when it will stop indexing. Any thoughts 🤔

@mikeoniron All you really need

Remember the old days?

@sfreeman166 @nandoprince93 Restart had no effect. Still at 92% after 4 days...

@jasonball @nandoprince93 have you tried restarting your phone? i seem to be stuck at 83%

Dear Merican Frens, You can destroy our Soccer team but you can’t take our BISCUITS! I recommend you start with origin before taking on double coat.
