Happy Star

What Is Happy Star?

Happy Star is a family-oriented mobile application built for Android that transforms everyday tasks and responsibilities into an engaging, star-powered adventure for children. Parents assign tasks, children complete them, and stars are earned. Those stars unlock real rewards — chosen by the family, meaningful to the child.

At its core, Happy Star is a habit-building platform that speaks the language children already understand: fun, progress, and reward.

Hapsched

What is Hapsched?

Hapsched is a focused, no-frills platform built for one job: helping event organisers list their events and run a clean, fair Call for Papers (CFP) process. No image carousels to fuss over, no bloated ticketing system to configure — just the information that matters, presented clearly, with a workflow that actually fits how conferences, meetups, and hackathons get their talks selected.

The Problem It Solves

Anyone who has organised a conference knows the CFP scramble: submissions land in a shared spreadsheet, reviewers email back and forth, feedback gets lost, and speakers are left wondering if their talk vanished into a void. Meanwhile, most event listing tools are built for ticket sales and flashy banners — not for the messy, human process of finding and vetting great speakers.

PromptChef

Mon, 01 Jan 0001 00:00:00 +0000

What Is PromptChef?

PromptChef is a community-driven library of AI prompts and skills. The library itself lives as an open-source GitHub project, where prompts and skills are contributed as markdown files. PromptChef wraps that project in a simple website at promptchef.net so anyone can browse and find what they need without digging through a repository.

The Problem It Solves

Useful AI prompts and skills exist all over the internet — scattered across blog posts, tweets, gists, forums, and other people’s private notes. There is no single, consistent place to find them, and no agreed structure for sharing or discovering them. Every time something genuinely useful is shared, it tends to disappear into whichever platform it was posted on.

Why Happy Star Isn't Just Another Chore Chart

Reward charts on the fridge fail for a predictable reason: they ask a child to delay gratification for a week before anything interesting happens. By day three, the chart is just wallpaper. Happy Star exists because the underlying idea — give kids a structured way to build habits — is sound. The execution most families have access to is what’s broken.

Building Happy Star meant making a handful of deliberate design choices about how gamification, parent involvement, and data should actually work. Here’s why we made them.

Why We Built PromptChef

If you’ve spent any real time experimenting with AI tools, you know the feeling. You’re scrolling through social media and someone shares a prompt that’s genuinely good — the kind that gets exactly the output you’ve been struggling to get for weeks. You bookmark it. Or you take a screenshot. You tell yourself you’ll come back to it.

You don’t.

The bookmark graveyard

A month later you’re looking for that prompt again, and you have no idea where it went. Was it a tweet? A Reddit comment? A screenshot buried somewhere in your camera roll between fifty other screenshots? You scroll, hoping you’ll recognize it when you see it. Usually you don’t. You write a worse version from memory and move on.
