I watched 30 users talk to the same voice agent Same script. Same questions. The only thing I changed was the response latency: 300ms, 500ms, 800ms. At 300ms, people just talked. No awkward pauses, no confusion. One user didn't even realize it was an AI until I told her afterward. At 500ms, something shifted. Users started talking over the agent. They'd ask a question, wait half a second, then r
Hey Dev Community, Like many of you, I hit a wall with GA4. It’s powerful, sure—but it’s also cluttered, slow, and often feels like it was designed for a data scientist rather than a developer or a brand owner who just needs to see what’s working.

The landscape of mobile development is shifting beneath our feet. For years, "Smart Apps" were simply thin clients for powerful cloud APIs.

After getting frustrated with news apps designed to keep me scrolling forever, I built Trace - an Android app that aggregates news from 100+ sources and uses AI to create 30-second summaries. The app is free, no ads, no subscription. Just news that respects your time. The Problem Every morning I'd open Google News or Twitter and 30 minutes would vanish.

The "Unsharable" Dashboard Problem Imagine this common B2B SaaS scenario: An executive opens your analytics dashboard. They spend three minutes configuring the data—they filter the status to "Active," set the date range to "Last 30 Days," sort the table by "Highest Revenue," and navigate to Page 4. They copy the URL and Slack it to their team lead. The team lead clicks the link, but instead of see
