An upstream metric that can be measured daily is sleep slow-wave activity or delta power.

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.

Also only works with iPhones, oops.
We're reviewing this, but don't have an update just yet.

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

That's a strained claim to make. From a quick search assist response: "As of 2026, there are approximately 3.5 billion active Android users and around 1.5 billion active iOS users globally"

How are you serving the larger customer base by being iphone only?

We're not shipping globally to start. Australia (where we're based) and US only. When we look at our user groups, they are almost entirely iPhone.
The user groups of an iPhone app will be overwhelmingly iPhone users, I reckon.
