The fraudsters seek out people who just want to talk and be heard, who don't have someone else to call on.

It is somewhat surprising to me that banks don't implement a multi-signature account types for people at risk. Particularly for any transfers to new accounts or even purchases.

The big complaint is that the amount of work to get the level of polish needed in premium apps just isn't there. Or you need to do a bunch more work and it isn't significantly different than the amount of work of getting a native iOS and native android dev.

After reviewing a bunch of packages, one of our devs decided this was probably the best available. I'll mention the new Nordic, as we are based on nrf chips.

However, I don't think it is so much of a signal of your brain having an idea of how long you've been awake, that's the circadian cycle. I always looked at adenosine as a driver of sleep need. If you burned this much ATP, we're going to need to recover. Seems like an elegant process.

We built iOS first because that's what most of our users have, though the team is mostly on Android.

We built our logic in Rust, so that compiles cross platform. It's really just the UI layer that is per platform.

Though I had initially written our first demo in React-Native, the team wanted to go with native UI.

Lately we've been talking about moving the timeline for our Android app up because we can get AI to help using the iOS app as a foundation.

I haven't seen anything really new and compelling in iOS/Android land. The promise of right once run anywhere continues to be a promise, and the bluetooth libraries across different devices (particularly in Android land) has me concerned.

Most of our team are daily Android users, including me, but we need to serve the larger customer base.

This is the synchronous firing of neurons which define restorative deep sleep, and one of the primary patterns which we describe as the Neural Function of Sleep.

This Neural Function of Sleep naturally declines with age, but more importantly, through stimulation we can enhance it which research is showing improves immune function, increases HRV, and more.

So while the original post discusses markers they expect to measure every 3 months, our work at https://affectablesleep.com measures the Neural Function of Sleep daily, but not to give you a score, but to actively support how well the brain sleeps, not how long.

Though there are over 50 published peer-reviewed papers in these techniques, I'm curious to see if we begin stimulation in our 30s, prior to the decline in sleep, do we slow the rate of decline as we age, as well as supporting daily function.

The structure of the app is in rust, so that is shared across platforms. The challenge is in the UI elements, and the cross platform stuff just isn't as good as going native there. You end up building a bunch of custom components anyway.

I'm also a bit wary of BLE on Android. iOS, is a bit more of a known entity.

It isn't just iOS and Android either. Because we support researchers, we also have a web app that they use. It surprising how large our technology footprint is across services, firmware, web, and apps.

What makes you think an EEG headband is not just a smartwatch in a different form-factor? We're running an nrf53 plus extra storage. We don't have a screen, but screens are fairly inexpensive. We've got a full EEG system.

We have actually done pretty well at limiting the number of parts. The headband is so thin it's buttonless. We didn't have room for a button and created a fully buttonless interface.

There are parts you wouldn't think would be expensive but are. Bone-conduction transducer, heart-rate sensor, etc etc. Yes, we could ditch the HR and save some money but we feel it will be beneficial.

Watches are a thing that exists. EEG sleep headbands aren't. We had to create our own materials for EEG sensing. Everything else on the market have limited life and aren't comfortable enough for sleeping.

Of course, all the plastics and TPU are custom. The fabrics are custom. Our scale is also very small right now, so I fully expect the cost to come down significantly with scale.

It was always in the plans, we're all actually on Android, but we wanted to get the user experience right on one platform and not spread ourselves too thin, but we're thinking AI makes a big difference here, so... no announcement yet, but it was never going to be iPhone forever.

I still can't say for sure we'll have android at launch, but we'd like to.

We decided to go with a low device cost and subscription to make it cost effective to purchase when finances allow us to get to a monthly instead of yearly subscription.

When we first started, many in the sleep community were against using these techniques. A significant number of the studies look specifically at safety, and often people report to these as "null results" when in fact what was being examined was the potential negative impact.

One example is the study on metabolic function [1], which showed no result in healthy men. It did not harm their metabolic function, though it also didn't improve it (though I'm not sure how you would measure improvement in healthy metabolic function).

For our company, there are many modalities and capabilities we are building for the future, we began with auditory stimulation and this one in particular due to the low-risk and volume of research.

This is why we describe the neural function of sleep, but can't specifically get into details regarding increases in slow-wave activity, 15% decrease in early night cortisol, 14.5% increase in HRV, etc etc. We can link to the research, but can't say "this is what we do".

We are relying on user testimonials, which we are gathering through our beta testing and beyond.

At the same time, we do describe the "clearer thinking", "immune function", "stress" etc about half way down the page.

It's something we will continue to get better at.

I work in neurotech/sleeptech and one of the biggest challenges I see in our industry is, if not pure snake-oil, the over-hype of "backed by research".

People have accused us of being snake-oil as well, and I get why they might think that if you haven't read or don't understand the science.

I've seen products that claim to be Vagus Nerve stimulators that are worn on the wrist, nowhere near the vagus nerve. Products that claim to mimic the "magnetic frequency of hormones".

We've also got the current "It's got electrolytes" craze which is kinda crazy that we've truly replicated idiocracy.

For those curious, I'm the co-founder of affectablesleep.com

1) Though they are comparing parents specifically, without the baseline of what the hunter-gatherer groups sleep was like without children, are they comparing hunter-gatherer group to industrialized people? Or are they comparing parenting?

50% of people rate their sleep as an F, and another 21% a D grade [1]. That feels likely everyone is failing at sleep, not just parents.

2) specifically in mothers, as motherhood has shifted later in life, the early years with young children are now often overlapping with perimenopause, so mothers are hit with the double whammy of sleep disruption. I blogged about this a few months ago [2]

The study is still mostly focused on the antiquated idea that sleep duration is a predictor of sleep quality. The latest research shows sleep regularity is a better predictor of morbidity than sleep duration. I wrote about hot the Neural Function of Sleep dictates this [3]. Studies in shift workers (I can never find the link) shows regularity trumps duration for both subjective sleepiness and cognitive performance.

The article does mention the increase in prolactin during breastfeeding, but the tiredness of parenting doesn't only last through the first year (apparently the average of breastfeeding in Australia is 6 months). The hunter-gatherer societies I'm sure breastfeed for longer periods.

I work in neurotech/sleeptech as the co-founder of affectablesleep.com and we have a keen focus on parents of young children and specifically enhancing the Neural Function of Sleep, not sleep duration which everyone obsesses over [4].

I never would have imagined that OpenAI is sending the full audio of a request to their servers. I had always assumed the audio was transcribed locally and then sent to the server.

The only reason I can think they'd want the full audio is for later model training, which, ok, fair-enough, but this can still likely be done without the limitations of WebRTC.

I can't think of a single time I've looked at a product tour and thought "well, I'm really glad they told me that, I never would have figured that out.

What the product tour I think often misses is that people don't want to learn your entire tool at one time.

They came to do one thing, that one thing needs to be brain dead simple.

Over time, you can show people what else they can do. But a product tour isn't the way to do that.

I think progressive UIs where you expose more and more to the user over time is the way to go.

If you're thinking "but I have so many features and capabilities this person needs" you probably haven't identified what the one thing people are paying you for is.

Computers were nowhere for ever, then everyone had them. The internet was tiny, then everywhere. Smartphones were a teensy market, then everyone had them. GLP1s were for a small group of diabetics, now a significant portion of the population take them.

This is how things playout time and time again.

Does it mean the commentors 10 years is correct? No. But it also doesn't need to be incredibly optimistic. All it takes is getting the robots right, and there are multiple companies who seem very close.
