#Ask2Color is officially published on both platforms: Android and iOS. I’m very happy to reach this milestone. Now you can enjoy and enhance your kids’ imagination. Let’s start creating those drawings! #shipaton @RevenueCat Android: play.google.com/store/apps/det… iOS:…


I’ll be uploading the #Ask2Color app to the @solanamobile Store, making it available for Seeker phones. In this version, I’m updating the paywall to include the option to pay with crypto by connecting your wallet directly. Next, you’ll be able to mint your kids’…

Kotlin for full-stack development is growing, and the learning resources are evolving with it🔖 A great example is @plcoding's new 56-hour course: build a full KMP chat app (Android/iOS/Desktop) + Spring Boot backend. The 30% launch discount ends today! pl-coding.com/full-stack-bun…


What is happening with the @AppStore algorithm?? On the first day of my app launch, I was #10 in "coloring apps for kids" and #44 in "drawing apps for iPad." Now I have no ranking at all. I'm targeting all the keywords with a difficulty below 65. Hopefully, my update with the…

Scan toys into kids’ drawings! The new #Ask2Color feature is waiting for review! The updated screenshots, created with my screenshot generator and inspired by @adamlyttleapps’ latest video recommendations, are included in this update. I’m improving the generator with feedback…

#Ask2Color launched yesterday on the App Store and already has its first customer. Whoever you are, thank you! I hope your kids enjoy the app as much as mine do. 🙏 I’m finishing the Photo2Color feature, which is almost ready to ship. 🔥 #buildinpublic #shipaton @RevenueCat

I needed to make a very simple audio player with an infinite loop for the app. I wanted to use Skia on iOSMain, but it was taking too much time, so I decided to change the approach and use an interface instead. It was easy, I just created the interface in Kotlin and then made…

I made a promo video for my #Ask2Color app. It’s incredible what you can create all by yourself in no time, nowadays. I used: @nanobananai @GeminiApp @elevenlabsio #Veo3 from @Google @figma #iMovie It might be basic for some people, but I’m very happy with the results!…


It was naive to think that it would pass on the first attempt. I have never submitted a kid’s application before. There are some extra considerations to be aware of 😅 #Ask2Color #buildinpublic #shipaton @RevenueCat

Improving the new feature of #ask2color by adding a flash and a preview for confirmation. #buildinpublic #shipaton2025 @RevenueCat


What’s great about the Build section of @googleaistudio is that your solutions integrate seamlessly with the Gemini API, no configuration needed. I made a web app to create screenshots for my apps, powered by #nanobanana. We are truly living in the future right now...…


#ask2Color New Feature!! Now kids can color their favorite toys! Leveraging #nanobanana, I’ve added a new feature to the app that lets you take a photo, extract the main object, and get it ready for coloring. Check it out!! #buildinpublic #shipaton @RevenueCat @levelsio

I was testing #nanobanana so I vibe coded an AI Product Ad Generator using @googleaistudio that use #gemini25flashimagepreview to generate the images. This will, without a doubt, be my next mobile app. So I gave it a try and generated some cool content to promote my #Ask2Color
