I Built 80+ Android Apps as a Solo Developer — Here Are Two of My Favorites

Hi! I'm a solo Android developer from South Korea. Over the past few years, I've built and published over 80 apps on Google Play — all by myself.

Today I'd like to share two of my favorite apps:

🎯 Russian Roulette — Party Game

A thrilling party game where players take turns pulling the trigger. Set the number of players, load the chambers, and see who survives! Perfect for parties and gatherings.

🎂 Blow Cake — Birthday Celebration

Blow out birthday candles on your phone using the microphone! A fun way to celebrate birthdays anytime, anywhere — even remotely.

Both apps are made with Flutter and include 12 language translations. I'd love to hear your feedback — I actively incorporate suggestions into updates!

Building a Russian Roulette game where nobody, including the code, knows the outcome until the trigger fires

I wanted to make sure that even inspecting the app's state right before the shot couldn't reveal the outcome, so the bullet's chamber position stays undetermined-in-practice until the trigger animation completes.

Players choose 1 to 5 rounds for the cylinder ahead of time. Two modes are included, a spinning wheel and a spinning pistol, so groups can switch styles depending on the mood.

One rule I kept strictly: the three screens where the actual shot happens have zero ad placements, since that's exactly where fingers land in the moment.
