To my new followers 👋 Here is the story behind my handle "KotoApp". It represents my core philosophy as a developer. 👇 Read here note.com/kotoapp/n/ndb06fea0…

TikTokに僕の資格アプリの動画をアップロードしたいと思ってKling AIでマーケ動画を作ってるんだけど、あとちょっとだけ日本語安定してくれないかねええ～～～😇

Now they're playing "Red Light, Green Light." 🚦 I usually just watch them passively, but recording it like this makes me realize just how many different things they do in a day. Study, art, drama, and now sports... kids are busy! 😂

Study time is over, and creativity time begins! 🎨 My oldest drew a castle and clouds, taped them to the wall, and started a princess story. Now the youngest is busy drawing new characters to join in. ✍️ I love their imagination! ✨

Study time for the kids! 📚 The older one is on a tablet, and the younger one is doing workbooks. I’ve learned that just saying "Go study!" never works. 😅 So, I’m sitting right here with them to make sure it gets done.

Good morning! ☀️ Time to code. Starting my Sunday indie dev session now. 💻🚀

Sleeping all together tonight! Good night everyone! 🌙

My kindergartner started doing math last night... and didn't stop. 🤯 Started at "1 1=2" and went all the way up to "4096 4096=8192". I taught them basic addition, but I never expected a 6-year-old to calculate powers of 2 up to 13 bits! 1024, 2048, 4096... beautiful numbers for a developer parent. 😂

Dev Update: Escaped the "SDK Swamp"! 🐊 After struggling with Facebook SDK tracking issues yesterday, I finally managed to fix it. Meta Ads for "Pettan" are officially LIVE! 🚀 Launching ads feels a bit like sending your kid off to their first day of school. You just hope they behave well and make friends (users)! 😂 ■ Today's Progress Marketing: Meta Ads setup complete & launched. ■ Plan for Tomorrow 1. Localization (v1.0.3) Adding Spanish (Español) 🇪🇸 Adding Polish (Polski) 🇵🇱 Kids laugh the same in every language, so I want to remove the barriers. 2. Marketing Analyze ad performance data. Coding one day, marketing the next. The indie dev journey continues!

Logging off for the week! 💻 Time to sleep with the mini-team and recharge. Sleeping is the best debugging tool I know. Good night, everyone! Have a great weekend. 😴

Dev Update 🛠️ Trying to set up Meta Ads for "Pettan", but I'm completely stuck on Facebook SDK tracking issues. It just won't verify. 😩 Spending my limited free time fighting with configurations instead of coding is painful... but that's indie dev life. Tomorrow's goal: Fix this and launch the ads! 🚀

Just got the email from Apple about VAT changes in Bhutan, Zimbabwe, Finland, etc. 📧 Sometimes we complain about the 15-30% commission, but honestly? Having Apple handle tax compliance for 175 regions automatically is worth every penny. If I had to do this manually, I'd never ship a single line of code. 😅

Good morning! ☀️ The kids are still fast asleep. This quiet time before the chaos begins is my most productive coding session. 🤫💻 Time to make some progress!

Time to sleep with the kids! Resting the brain is just as important as writing code. Good night, everyone! 😴

I was "Client Zero" for my own app this morning. And honestly? It saved me. 🥺 The morning started rough. My youngest (preschooler) refused to eat breakfast for 30 minutes, just playing around. I lost my patience, snapped, and made them cry. The vibe in the house was terrible, and the "parent guilt" was kicking in hard. In a desperate attempt to fix the mood, I opened my app, "Pettan." My kid, still teary-eyed, agreed to tap the screen. We filled the gauge, and the mission that popped up was: "Make funny faces at each other 🤪" In an instant, the tension vanished. We both burst out laughing. My kid was happy again, but more importantly, my own anger and stress completely melted away. I realized today that I didn't just build a game for kids. I built a "reset button" for parents like me who sometimes lose their cool. It feels amazing to be saved by the software you wrote. Best QA session ever.

A classic! It’s basically a rite of passage for every dev. 😅 Quick fix and you're back on track! 🚀

I built a habit tracker that charges you real $$$ if you fail at keeping your habit. I noticed a ton of habit trackers are over-engineered and optimize for engagement & retention (understandably, they have shareholders or need to make money). So I made mine dead simple to use. I want my users to cancel as soon as they've built enough self-discipline to no longer need a habit tracker. For example, every time you complete your habit, you'll see an option to close your account. It's a psychologically-backed accountability mechanism that's not concerned with keeping you in the app longer than you need to. Currently in beta while waiting for Apple to approve it, lmk if you want a TestFlight invite! one-habit-app.com

what i found out about dev tools is nobody buys that shit

i've had the same to-do item for 3 weeks. "write content strategy doc." every day i look at it. every day i do something else. the gap between knowing what to do and actually doing it is where most plans die.
