Fixing my sleep, one night at a time 🌙
Building @SleepBestieAPP in public
Let’s sleep better together

[Rain JDesign @Rain_JDesign]

Solo-built this sleep app @SleepBestieAPP.
Every update is just me shipping and listening to feedback.
If better sleep matters to you, I'd love you to give it a look.

Big update! Your AI Sleep Tracker 1.0.8 is out🎉!

Sleep data alone doesn’t tell the whole story. V1.0.8 adds an Action tab so you can log daily routines (morning, daytime, bedtime)—and our AI uses them alongside sleep for richer insights.

Inspired by @zarazhangrui's follow-builders skill — I built my own version for US stock macro briefings.
Every morning at 6am: FRED data → Claude AI analysis → Lark push.

How I grew my X following by 10k in 3 months:

1. Tune your feed (unfollow clickbait, follow builders)
2. Engage authentically (don't use AI to write replies)
3. Post at least 3 times a day (write like how you talk irl)
4. Learn in public (use X as a public notebook for recording takeaways from podcasts/newsletters etc)

Do this consistently for 3 months.

The animations are buttery smooth. Seriously impressive execution!

[Zara Zhang @zarazhangrui]

I created a Claude Skill that make beautiful slides on the web. The world hasn't woken up to the fact that code can create much better slides than most PPT tools.

- Claude interviews you first about aesthetics, then generate a few directions to "show not tell", and you can pick your favorite
- Cool transitions and animations
- Interactive hover states and cursor effects
- Auto-fits on any screen
- Supports converting existing PPTX files to web-based slides; preserves original images and brand assets

I asked Claude to make a slide show about this skill to showcase what it can do.

@DrKristieLeong I sometimes go for avocado instead. It seems to work wonders too, but maybe that's just the 'healthy lifestyle' brainwashing at work lol.

[Kristie Leong M.D. @DrKristieLeong]

Stop megadosing Vitamin D until you read this.

Most people treat Vitamin D like a solo act. It’s not. It’s a Magnesium-dependent process.

Clinical reality: Case reports suggest that with severe Mg deficiency, even 600,000 IU of Vitamin D fails to work. The body simply stays "resistant" until Magnesium is added.

With over 50% of adults insufficient in Magnesium, we are seeing a silent epidemic of Vitamin D resistance.

The risk? If you push high-dose D without Mg, you’re not raising your "D" levels, you’re likely raising calcium and phosphate, which can contribute to vascular calcification.

The "D3-Magnesium" Action Plan

1. Food First: Add pumpkin seeds and leafy greens daily. Whole foods are the foundation for a healthy magnesium level.

2.Test RBC Magnesium: Don’t rely on "Serum" labs; they only show 1% of your body's stores. Get an RBC test to reveal intracellular stores.

3.The 2-Week Lead: If you’re starting high-dose D3, supplement Magnesium for 14 days first to "prime" the activation enzymes.

4. Match the Ratio: Avoid supplementing D3 in isolation . Anecdotal reports and mechanistic plausibility suggest Magnesium depletion underlies the restlessness and energy crashes some people experience on D3."

5. Add Vitamin K2: Take 100mcg (MK-7) to keep that calcium out of your arteries. (Talk to your doctor first)

Nutrients work in networks. Getting the cofactors right matters as much as the dose.

🍎Apple has a new CEO: John Ternus.
At 50, he’s the youngest exec to take the helm, marking a strategic shift back to hardware innovation.

[WOLF @WOLF_Financial]

SO WHO IS JOHN TERNUS, THE NEW CEO OF APPLE $AAPL?

• 50 years old, Apple’s youngest senior executive

• Joined Apple in 2001 as a product design engineer on the original iPod

• Mechanical engineering degree from Penn

• Has led all hardware engineering since 2021 (iPhone, iPad, Mac, Apple Watch, AirPods, Vision Pro)

• In January 2026, Apple expanded his remit to also include industrial design, the final step before the CEO appointment

The board’s case for him: continuity. He’s a product-and-operations executive in the Tim Cook mold.

[Rain JDesign @Rain_JDesign]

Exactly. My daily ritual: a 2km hike to the local café. 🌿
Rain or shine, it’s the best way to decompress and refresh my mind after a deep work session at home. Highly recommend getting those steps in! 👟

[Dan Go @CoachDanGo]

Walking stimulates the brain.

Walking helps you live a longer life.

Walking helps your body recover faster.

Walking helps you manage your emotions.

Walking helps you de-stress after a long day.

The easiest way to improve your brain & body is going for a walk.

@KristenJakobitz Spot on. I’ve learned the hard way that you can't out-willpower a spike in ghrelin. When the data shows a poor night's sleep, the cravings are almost inevitable. Prioritizing rest is the best 'diet' plan there is.

[Rain JDesign @Rain_JDesign]

7–9 hours is the exact duration threshold we use in @SleepBestieAPP, but it’s just the baseline. 📊

To give a true Sleep Score, we look deeper: fragmentation levels, consistency, deep sleep ratios, and alignment with your target goals. 🧠💤
#SleepBetter #HealthTips #SleepHacks

[Kristen Jakobitz @KristenJakobitz]

We can’t out-diet or out-train a lack of sleep. Poor sleep increases ghrelin (the hunger hormone) and decreases leptin (the fullness hormone). Want to lose weight? Prioritize your 7–9 hours.

Protein > Carbs for breakfast. 🍳

Hitting that 30g threshold is my secret to a high-output morning. It stops the catabolic cycle and keeps the focus sharp for deep work. Highly recommend for anyone sitting behind a screen all day. 💻🔥
#MorningRoutine #HealthTips

[Kristen Jakobitz @KristenJakobitz]

Why 30g of protein at breakfast? It’s the threshold to trigger muscle protein synthesis. If you're just having toast, your body stays in a catabolic state. Add eggs or Greek yogurt to flip the switch.

Lesson learned: One afternoon coffee = 1 hour of tossing and turning. 📉

As I get older, I’ve realized my biological margin for error is shrinking. I’m officially capping caffeine to 2x a week, strictly before noon. Protecting deep sleep is a non-negotiable ROI.

[Kristie Leong M.D. @DrKristieLeong]

Look around the world of medicine today! So much of it exists to fix the damage caused by lifestyle choices we could have prevented.

Somewhere along the way, we started treating declining health as an inevitable part of aging when it's often the result of neglecting to makes changes before things fall apart.

Why not start making small, consistent changes today?

[Rain JDesign @Rain_JDesign]

@DrKristieLeong Spot on. In my 20s, I treated my body like a machine that never needed maintenance. Now, I’ve realized my 'biological margin for error' has shrunk. I’ve had to cut coffee back to twice a week and only in the mornings to protect my sleep.

[Rain JDesign @Rain_JDesign]

Apple watch seems to be the most well-rounded fitness tracker.
But as a developer building @SleepBestieAPP, I’ve realized: hardware is only half the battle. The real magic happens when we translate those raw sensors into actionable insights for a better life.

How accurate are wearables like Apple Watch, Whoop, and Oura?

A researcher compiled 16 studies to find out, and the answer might shock you:

[Rain JDesign @Rain_JDesign]

That's exactly why you should treat its data as personal trends only—not absolute metrics. The real value lies in comparing your own data over time, not against others' numbers.

Stop eating 3 hours before bed - checked ✅
#SleepHacks #HealthyHabits #BedtimeRoutine

[Dr. Rhonda Patrick @foundmyfitness]

One of the simplest things I do for sleep is to stop eating about 3 hours before bed.

It's something that’s supported pretty consistently in the research.

When you eat (especially a large meal), you’re activating the sympathetic nervous system... not what you want when you’re trying to wind down and get into deep, restorative sleep.

If you occasionally eat late, it’s not a big deal. But as a habit, giving yourself that 3-hour buffer can make a meaningful difference. If you do need something before bed, keep it light - something like a small protein shake rather than a heavy meal.

From my recent appearance on the Diary of a CEO podcast w/ @StevenBartlett.

[Rain JDesign @Rain_JDesign]

@DrKristieLeong That's basically everything you need for a healthy and happy life. I've come to believe you truly are what you eat, and how well you sleep.
As an indie developer, I also find social ties to be incredibly important, especially when your work can be isolating.
