Why I Still Believe in One-Tap Counting (And Built a Tool for It)

lemon chen — Thu, 30 Apr 2026 07:54:55 +0000

We've all been there. You're at the gym, mid-set, trying to remember if this is rep 8 or 9. You're at a warehouse, clipboard in hand, losing count of inventory boxes. You're at an event, clicking a handheld counter that just broke. Or you're deep in prayer, fingers moving over beads, when your mind wanders and you lose track.
The count was important. The tool made it harder.
The Problem with "Feature-Rich" Counters
Modern counting apps love complexity. Dashboards. Data export. Trend analysis. Cloud sync. What started as "tap to count" became a fitness ecosystem with social sharing and subscription tiers.
Don't get me wrong — complex tools have their place. But for the simple act of counting something? We've over-engineered the solution.
I don't need weekly counting reports for my gym reps. I don't need cloud backup for my event attendance. I need a number that goes up when I tap. Fast.
What Simple Actually Means
Simple isn't about lacking features. It's about zero friction between intent and outcome.
When I built Counter Online, I had one rule: no steps that don't directly produce a higher number.
Here's what that looks like in practice:
One tap = +1 — anywhere on the screen, even with gloves on
Multiple counters — run inventory and foot traffic simultaneously
Reset in one tap — no confirmation dialogs, no "are you sure?"
Works offline — because warehouses and basements have no signal
No account. No "verify your email." No "upgrade for unlimited counters." The count goes up, your focus stays where it belongs.
Who Actually Uses This?
I expected gym-goers and warehouse workers — people counting physical things all day. And they do use it.
But the usage surprised me:
Nurses tracking patient vitals during rounds
Researchers counting bird species in the field
Event planners managing multiple entrance counts
Muslims doing tasbih and dhikr during prayer
Knitters tracking rows in complex patterns
The common thread? They all had something to count and zero patience for app complexity.
The Hidden Cost of "Free" Counters
Every "free" counting app that requires an account is extracting value from you. Your email. Your usage data. Your attention (hello, weekly "progress" emails). Your time spent navigating subscription pages.
A truly simple tool respects that your time and data have value. That's why Counter Online doesn't ask for either.
When Simple Wins
Simple tools win in three scenarios:
Speed matters — mid-workout, mid-prayer, mid-event; you can't pause to wrestle with an app
Context switching kills — you're in flow state; opening a heavy app breaks concentration
The task is universal — everyone counts things, not everyone needs analytics on their counting
The Counter-Argument (And Why It's Wrong)
"But what about history? What about graphs? What about exporting to Excel?"
Valid needs. But they're separate needs. The mistake is bundling them into a tool that claims to handle "all your counting needs." Now you have a mediocre logger, a mediocre analyzer, and a slow counting flow.
Do one thing well. Let users combine tools for their specific workflow.
Try It (Or Don't — That's the Point)
Counter Online exists because I got tired of apps making counting harder than using my fingers. If you count things — for work, for fitness, for prayer, for whatever — try it: https://counter-online.com/
Or don't. The beauty of a tool that requires no commitment is that it costs you nothing to ignore it. But when you need it, it'll be there — no password reset required.
What's your "simple tool" that you use daily but never talk about? Drop it in the comments.

Complete list of symbols for your website

lemon chen — Wed, 25 Mar 2026 11:06:07 +0000

What is a web symbol?
Web symbols or HTML symbols are short HTML snippets, commonly referred to as character entities or entity codes, used to display characters that have a special meaning in HTML, as well as characters not available on the keyboard.

Web symbols have existed since the appearance of electronic keyboards due to programming needs, but they have greatly expanded with social networks like WhatsApp, becoming almost a new language and form of expression.

The most common and necessary web symbols have easy shortcuts indicated on our keyboard (e.g. % @ €), or can be created using key combinations that many of us know and use (e.g. 😉 ), but most HTML symbols are not easily accessible, so the easiest way to use them is the classic copy/paste method we all know.

If you’re a fan of these icons, here you can get custom backpacks or a personalized backpack with these symbols or other images that inspire you. Yes, they are sponsored links 😛 and although we at Marabelia write for the love of it, money is money 😅
Symbols to Copy and Paste on Your Website
At Marabelia (Web design in Valencia) we’ve decided to create a complete list of the most useful, original, and interesting web symbols (web icons) for use on your website, emails, and social media… since these symbols are supported by all modern browsers.

Without the need to install libraries like Icomoon or embed images from Flaticon, we can add images compatible with most browsers that are especially useful for contact sections and to bring our text to life. To use them, just select the icon, copy it, and paste it into your website. 🙂

Building a Zero-Dependency Fullscreen Color Tool: Lessons from PinkScreen

lemon chen — Mon, 09 Mar 2026 07:16:22 +0000

Last month, I shipped Pink Screen—a dead-simple tool that displays fullscreen colors for video backgrounds, livestreaming, and display testing. It now serves 100K+ monthly active users with zero server costs and 100 Lighthouse performance scores.

Here's how I built it, and why sometimes the simplest architecture is the most scalable.

The Problem: Existing Tools Were Bloated

Before PinkScreen, creators and developers faced three options:

Photoshop/GIMP: Overkill for displaying a solid color
YouTube "color screen" videos: Ads, compression artifacts, internet dependency
Other online tools: 2MB+ JavaScript bundles, analytics trackers, sign-up gates

I needed something that just works—instant, private, and frictionless.

The Architecture: Less is More

Core Philosophy: CSS-First, JavaScript-Optional


html
<!-- The entire "app" -->
<!DOCTYPE html>
<html>
<head>
  <style>
    * { margin: 0; padding: 0; box-sizing: border-box; }
    body { 
      background: #FFC0CB; 
      height: 100vh; 
      width: 100vw;
      cursor: pointer;
    }
    .controls { 
      position: fixed; 
      bottom: 20px; 
      left: 50%; 
      transform: translateX(-50%);
      opacity: 0;
      transition: opacity 0.3s;
    }
    body:hover .controls { opacity: 1; }
  </style>
</head>
<body>
  <div class="controls">
    <button onclick="download()">Download HD</button>
    <input type="color" value="#FFC0CB" onchange="updateColor(this.value)">
  </div>

  <script>
    // Only 847 bytes gzipped
    const fullscreen = () => document.documentElement.requestFullscreen();
    const updateColor = (c) => document.body.style.background = c;
    const download = () => {
      const canvas = document.createElement('canvas');
      canvas.width = 3840; canvas.height = 2160;
      const ctx = canvas.getContext('2d');
      ctx.fillStyle = getComputedStyle(document.body).backgroundColor;
      ctx.fillRect(0, 0, canvas.width, canvas.height);
      const link = document.createElement('a');
      link.download = `pinkscreen-${canvas.width}x${canvas.height}.png`;
      link.href = canvas.toDataURL();
      link.click();
    };
    document.body.addEventListener('click', fullscreen);
  </script>
</body>
</html>

Building a Production-Ready Clipboard Image Uploader with Next.js: Lessons from Paste Image

lemon chen — Mon, 09 Mar 2026 07:02:39 +0000

As a full-stack developer who recently built Paste Image, I want to share how Next.js 14 enabled us to create a lightning-fast, SEO-friendly clipboard image uploader that handles client-side image processing with zero server costs and maximum privacy.

Technical Architecture Highlights

Next.js 14 with App Router

Leverages React Server Components for instant initial page loads while maintaining seamless client-side interactivity for paste-and-go workflows.

Zero-Server Image Processing

All image manipulation—paste, crop, resize, format conversion—happens entirely in the browser using the Canvas API. This ensures zero server costs, instant processing, and complete privacy (images never touch our servers unless users choose to host them).

Dynamic Imports for Performance

Heavy editor components are lazy-loaded to keep initial bundle size minimal, achieving sub-second Time to Interactive even on mobile networks.


javascript
// Our dynamic import strategy for the image editor
const ImageEditor = dynamic(() => import('@/components/image-editor'), {
  loading: () => <Skeleton className="h-[400px] w-full" />,
  ssr: false // Client-side only for clipboard API access
});
