Of course, it needs work, but now it's compiling again and with Compose Multiplatform!
And 95% of the work was done by Codex! Both by chatting in the web version while travelling and with the CLI.

Now with AI, I'm trying to resurrect my old project MoneyFlow (github.com/prof18/Mo...) and make it Compose Multiplatform. Also, making it simpler without unnecessary stuff 😅
All will be done by Codex in the background while I do something else. Let's see how it goes 😅

It's @marcogomiero.com's turn to talk to us about the lessons learned after building apps with Kotlin Multiplatform 🧩
Here are the slides of my talk @Droidconit about what I've learned after years of building with Kotlin Multiplatform!
Lessons learned after building apps with Kotlin Multiplatform - Marco Gomiero
With Kotlin Multiplatform and Compose Multiplatform, you can share code and UI across multiple platforms, from Android and iOS to macOS, Windows, and Linux. But building apps on all these platforms brings unexpected challenges you don’t anticipate at the beginning. In this talk, I’ll share what I’ve learned (often the hard way) while developing apps with Kotlin Multiplatform. You’ll hear why sharing less code can sometimes save more time, how dealing with the iOS Keychain from background services turned into a debugging odyssey, and why placing your database in the wrong Windows folder can lead to silent data loss during app updates. We’ll also cover sandboxing on macOS, the trade-offs between using interfaces and expect/actual, and the complexities of distributing apps across platforms. Whether you’re just getting started with Kotlin Multiplatform or already deep into it, this talk might just save you from a few future debugging headaches..

Nowadays, when I have a new bug/idea/whatever for my apps, before writing it down in my task manager, I write it down on Claude Code Web as well.
The agent will start working on it, and then I will have something to improve or just review and merge it.
I love it!

The feature that I regret the most adding on FeedFlow are notifications.
Without a server, notifications are unreliable. On old Android devices or some devices things doesn't work.
On iOS limitations are stricter.
I'm thinking of dropping the entire feature, too much headaches

So, if you type "rss reader" on the web version of the Play Store, FeedFlow is the first result. 😱😱😍
On the Play Store on Android, it's in 3rd place 😍
