A month ago, I built Coffee Police because I wanted to get the most out of my caffeine, not just avoid the crash but actually understand what it's doing in my body. This week, JAMA published a 43-year study on 130,000 people that made me feel very vindicated. They found that 2-3 cups of caffeinated coffee a day cuts dementia risk by 18%, even for people with high genetic risk. Here's the catch, though: caffeine has a half-life of 5-7 hours. So, that afternoon cup can still be very much active at bedtime, disrupting the sleep your brain needs to get those benefits in the first place. Drinking coffee for brain health while letting it wreck your sleep kind of defeats the point. That's the gap Coffee Police is built to fill. It tracks your active caffeine levels in real time and tells you when to stop for the night, based on your bedtime and how sensitive you are to caffeine. Free, no subscription, no ads. When do you usually have your last cup? https://coffeepolice.net/
Something clicked for me this week reading about what's happening in the advertising industry.
AEDEMO 2026 basically declared the end of GRPs those broad reach metrics the ad world has used for decades. A major Spanish broadcaster just launched an AI system that measures actual attention in TV ads: not impressions, not eyeballs-in-the-room, but genuine cognitive engagement. The industry finally admitted it had been measuring what was easy to count, not what actually mattered.
I want to share something I've been building - Upvotics, a competitive intelligence platform for founders, marketers, and product teams who are tired of finding out what their competitors changed way too late.
The problem I kept running into was simple. A competitor quietly updates their pricing. Launches a new feature. Shifts their messaging. And you only find out weeks later when a prospect mentions it in a sales call or you stumble across it by accident.
Upvotics fixes that by turning competitive intelligence into an automated process. You add your website and your competitors, and Upvotics handles everything from there. It scans their pages on a schedule, detects every change, runs it through AI to explain what changed and why it matters, and delivers clear intelligence so your team can act fast.
I built CoachingPortal because I kept watching talented fitness coaches burn out on admin instead of coaching.
They were duct-taping together 4 5 different tools - a training app, a nutrition tracker, a client portal, a spreadsheet - none of which had their brand on it, and none of which talked to each other properly.
What if you could search for cheap flights across multiple dates at once? StealthFlights has a Flexible Dates feature that does exactly this: pick a travel window and trip length, and we check every date combination to find the lowest price.
No other product offers this. Check it out stealthflights.com
We get very different answers depending on who we ask.
Some people are completely on board. They want the data, the analysis, the verdict, and they'll factor it in alongside everything else they know. For them, AI is just a faster, more rigorous way to get to the same place they were heading anyway.
Let's be real. Most health and productivity apps are too soft. They give you a pat on the back for doing the bare minimum.
I needed raw accountability to fix my energy at the root. So I built Circa Accord.
It's a neuroscience-backed sleep and circadian rhythm tracker, guided by Coach Don a hardcore, no-BS coach who won't baby you. He gives you the raw data and tells you exactly how to fix your day. Zero excuses.
