  "Daddy, what's this?" My 30-month-old son asked as he pointed to a red apple for the first time. At that moment, something stirred deep in my heart. It was the earnest desire to be part of every moment as this little being discovers all the colors of the world. A Father's Heart Coding Through the Night After my son fell asleep, in the quiet of the night, I sat at my keyboard and thought: "Instead of all those flashy apps out there, I want to create something truly meant for my child." Night after night, sometimes until dawn. Looking at my son's sleeping face, I poured love into every line of code. This wasn't just app development. This was the time I spent creating a real gift that a father could give to his son. What It Means to Be a Father Every day of raising a child, I learn something new. How can I love this little being better? How can I show him all the beauty in the world? "Toddler Color Cards+" was born from such a fathe...

My 29-month-old son, Junseo, is in the stage where everything sparks his curiosity. As we walk down the street, he constantly asks, “Daddy, what’s that?” or “What do you call this?” One day, we visited the zoo, and I still remember how excited he was. When he saw an elephant, he shouted, “Elephant!” with joy. Even after we got home, he kept asking, “Where did the elephant go?” So my wife and I started looking for an educational app that could help him learn new words. But most of the apps we found were disappointing — either too complex or filled with ads that distracted him. Some were just simple flashcards that he quickly lost interest in. Then I thought: “Wouldn’t it be great if there were an app where our child could learn naturally and have fun doing it?” That simple thought led to the creation of Toddler Word Cards+ . We designed the app from a child’s perspective — simple, cute, and fun. And from a parent’s perspective — safe, focused, and ad-light. We added features th...

 No More Worries About Smishing! Introducing the Android App "Secret Album+"  Hello, I'd like to introduce you to my recently released Android app "Secret Album+." I'm writing this post hoping that this app, which I've devoted a long time to developing, will be helpful to many people.  **No More Worries About Smishing!**  These days, there are so many smishing texts and suspicious links going around, right?

It thoroughly protects your precious photos and videos from access through suspicious links or messages. You can definitely reduce concerns about personal information leaks through smishing.

When you take your first steps into the world of Android app development, you encounter unexpected challenges and moments of achievement that intertwine. Today, I'd like to share the development story of my app "Auto Start+" that I recently launched on the Play Store. The Seed of an Idea It all began with a personal inconvenience. I found it tedious to manually launch all the necessary apps every time I turned on my smartphone. The thought, "Wouldn't it be convenient if frequently used apps started automatically when I turned on my phone?" became the seed for the "Auto Start+" app. Trial and Error in Development Initially, I intended to implement just the automatic app launch feature. However, wrestling with Android's permission system proved more complex than anticipated. Obtaining background execution permissions on newer Android versions was particularly challenging. One night while coding, the system suddenly crashed, and hours of work...

  Keep Your Precious Moments Safe: Protect Your Personal Photos with 'Secret Album' App Hello everyone, I'm excited to introduce my first Android app 'Secret Album' as both a developer and a father of two children. Development Background: A Project Born from a Father's Heart At 52 years old, raising two young children (a 27-month-old son and an 8-month-old daughter) has taught me many things. Capturing my children's precious moments through photographs brings me immense joy, but I've also realized how important it is to keep these personal photos secure. When lending my smartphone to friends or acquaintances, I often worried about accidentally exposing personal photos while opening the gallery to show them something. Photos of my children, family vacations, scanned important documents... These concerns eventually led me to create the 'Secret Album' app. What is 'Secret Album'? As the name suggests, 'Secret Album' is a secure...
