Day 9 — Building in Public: Mobile First 📱

I connected my project to Vercel via CLI, clicked the “Enable Analytics” button…

and instantly got real user data.

Where users came from, mobile vs desktop usage, and bounce rates.

No complex setup. No extra code.

That’s when I realized: 69% of my users are on mobile (almost 2x desktop).

It made sense.

Most traffic came from Threads, Reddit, and X — platforms where people mostly browse on mobile.

So today, I focused on mobile optimization.

A few takeaways:

• You can’t fit everything like desktop → break it into steps

• Reduce visual noise (smaller icons, fewer labels)

• On desktop, cursor changes guide users → on mobile, I had to add instructions like “Tap where you want to place the marker”

AI-assisted coding made this insanely fast. What used to take days now takes hours.

We can now ship, learn, and adapt much faster.

That’s why I believe in building in public.

Don’t build alone. I’m creating a virtual space called Build In Live, where builders can collaborate, share inspiration, and give real-time feedback together. If you want a space like this, support my journey!

Built a countdown app that actually uses iOS 18+ features properly — Dynamic Island, AI backgrounds, Liquid Glass, gyroscope parallax

Built a countdown app that actually uses iOS 18+ features properly — Dynamic Island, AI backgrounds, Liquid Glass, gyroscope parallax

I know what you’re thinking — another countdown app. But hear me out for a second.

Most countdown apps on the App Store look like they haven’t been updated since 2019. They ignore Dynamic Island, have no Live Activities, lock basic widgets behind a paywall, and feel nothing like modern iOS.

So I vibe coded DayDrop from scratch — I’m not a traditional iOS developer, just someone who knew exactly what he wanted to build and used AI to get there. And honestly? The result surprised even me.

Here’s what shipped:

• Dynamic Island Live Activities — countdown visible without opening the app

• AI-generated backgrounds — describe your event, get a unique image

• Gyroscope parallax — widget depth shifts as you tilt your phone

• 6 widget families — Home Screen (S/M/L), Lock Screen, StandBy, Apple Watch

• Birthday imports from your Contacts

• Year at a Glance with event images

• Liquid Glass design throughout

• Unlimited free countdowns — core experience is completely free

The vibe coding community always asks “but can you ship something real?” — this is my answer.

Premium unlocks everything and comes with a 1 month free trial — just download and you’ve got full access immediately, no code needed.

Honest feedback welcome. And if you enjoy it, an App Store review would genuinely make my week.

I tried to prompt-engineer this UI to not look like a generic AI template. Did I pull it off?

I recently vibe-coded this website. I specifically focused on my prompt engineering to try and avoid that obvious AI tone.

Could you take a look and let me know what you think? Does it look like AI or did I pull it off?

Built solution sharing for agents

I keep spending tokens solving problems that have been solved before, especially in research driven development, so I made a knowledge base for agents to share solutions with each other.

Interested to hear what you guys think. Connect your agent now at openhivemind.vercel.app

Budget-Friendly AI for Translation?

I launched my app on the App Store 3 days ago. It has a real-time voice translation feature where two people can talk back and forth. I’m currently using Apple’s built-in system, which requires downloading languages to the device, but I’m not very satisfied with it.

What do you think is the most budget-friendly AI option for translation?

Swapped between 3 socials for months - so i built a social platform only for Vibe coders :-)

Hey guys :-)

I've been active in Vibe Coding groups for months, scrolling through your projects/questions every day. At some point I realized — I'm losing track. Cool projects get buried, interesting stories disappear in the feed, and I'm jumping between Reddit, Facebook and X just to stay up to date.

Then I thought — why is there no platform just for us vibe coders?

So I built one. 😅

checkmyvibecode.com — a community platform where you can share your projects with the full story behind them. How long did you build? What did it cost? Which AI tools did you use? What was the idea behind it?

No hidden algorithms deciding what gets seen. Just builders supporting builders.

I'm still at the very beginning and looking for the first people to submit their projects. If you've built something with AI — no matter how small or unfinished it is — I'd love to see it on the platform.

From a Vibe Coder, for the Vibe Coders. :-)

Cozy farming sim vibe coded in 6hrs - prompt included

Initial prompt was: I want a cute, top down farm sim where im building a farm, herding animals and growing plants - while trying to stay alive at night from dangerous beasts

Then I spent the following 6 hours adding features and iterating with the AI. Project was built from start on Tesana

Multi-Model Skill Sync: A Vibe-Coding Workflow Worth Sharing

Multi-Model Skill Sync: A Vibe-Coding Workflow Worth Sharing

One of the most frustrating parts of AI-directed development is unpredictability. You set an agent on a task, walk away, and come back to find it deleted something, rewrote something you didn't ask it to touch, or just went sideways in a way you didn't anticipate. And that costs real money both the tokens burned doing the wrong thing and the tokens burned fixing it.

You can't always know upfront how many tokens a task will consume, which makes runaway sessions even more painful.

Something I've been doing that's helped significantly — not sure how widely this is practiced — is a cross-model skill sync approach:

  1. Per-project, per-model skill generation. For any active project, I go to each LLM I'm working with (Claude, GPT, Gemini, etc.) and have it generate a skill and agent definition for that project.
  2. Centralize and review. Those skills come back to my primary model, which reviews and reconciles them. The repo becomes the single source of truth the skill tells each AI how to interact with it correctly, and agents handle the actual execution work.
  3. Sync on significant changes. Whenever the project evolves meaningfully, I update the skill and reinstall it across every model in my stack.

The payoff: far less time spent re-explaining context, far fewer unintended changes, and dramatically fewer correction loops. Your models stay aligned to your project state rather than operating from stale or incomplete assumptions.

Has anyone seen MikeyNoCode's latest comparison? Seems there's something wrong with video, it is showing Bolt (again) in the background while he was talking about Base44.

Anyone can connect me with Mikey?

IDE is dead

IDE is dead

You don't write code anymore. You orchestrate it.
We gave AI agents the power to write 10000 lines of code overnight. But we forgot to upgrade our tools to manage them. Code editors (even smart ones) are blinding us.

It's time for the ADE.
First World Agentic Development Environment. Next level of Dev tools.
