Green Swagger

Green Swagger#

Green Swagger is an Android/iOS app built with Flutter for the 2024 Gemini API Developer Competition. While it was developed with release in mind, after considering multiple factors, I decided not to launch it, and the project is currently paused.

Why I jumped into the competition#

The first prize was a massive $300,000, and there was even a car as a giveaway prize that looked like it belonged in Back to the Future. From my perspective, it was hard to find a reason not to participate—so I committed to building a submission.

Walkholic#

Walkholic is an Android app that I released on Google Play around 2015. It has since been removed from Google Play for maintenance reasons.

Back then, fitness apps that tracked basic activities—like walking, running, and cycling—and recorded metrics such as activity volume and heart rate were just starting to become popular. Around the same time, Google launched the Google Fit API to grow an ecosystem, and a developer contest called the Google Fit Challenge was held. As you might expect, I joined the challenge and started building an app.

Mission Omok (TAKE FIVE)

Mission Omok (TAKE FIVE)#

Mission Omok (TAKE FIVE) is an Android game that I released on Google Play around 2014. It has since been removed from Google Play for maintenance reasons.

Back then, puzzle games like Candy Crush were booming. I remember thinking, “Gomoku/Omok is a familiar rule set, but maybe no one has really ‘claimed’ it with a standout concept yet.” So instead of building a plain Gomoku clone, I decided to create a version with a fresh theme and a mission-based structure.

Smart Browser#

Smart Browser is an Android browser app that I released on Google Play around 2012. It has since been removed from Google Play for maintenance reasons.

I built this app to submit it to an event in 2012 called “Google Hackfair.” Back then, the mobile market was a battlefield, and at the same time it still wasn’t as mature as it is today. I personally had a few pain points while using Chrome on Android, and when I decided to participate in Hackfair, I thought: “Then why not build the browser I want myself?”—and started the project.

Piano Keyboard

Piano Keyboard#

Piano Keyboard is an Android keyboard app that I released on Google Play around 2011. It has since been removed from Google Play for maintenance reasons.

This app started as a direct follow-up to my experience with No Look Keyboard. No Look Keyboard was an interesting idea, but in practice it was simply too difficult to use. So this time I wanted to build a keyboard with a lower learning curve—something you could try and immediately feel was fun. That’s how I ended up designing and building a keyboard concept based on piano keys.

No Look Keyboard#

No Look Keyboard is an Android keyboard app that I released on Google Play around 2011. It has since been removed from Google Play for maintenance reasons. For me, though, it’s not just “an old app”—it was my first experience building and actually shipping a side project, which is why I wanted to preserve it here in the archive.

The idea started from a very personal moment. One day, I felt motion sick while typing something on my phone on a bus, and I wondered: “Wouldn’t it be nice if I could type on a smartphone keyboard without looking at the screen?” With that, I began building a keyboard concept designed to let you keep your eyes forward (or on something far away) and rely more on finger sensation than visual feedback.
