I've been working on a small outdoor / ultralight hiking gear management app https://www.packrat.app. I've been getting some good feedback from memebers of the ultralight hiking community and am using this as an opportunity to learn Kotlin Multiplatform. My initial prototype was written in SwiftUI. From there I rewrote all the state management in a shared Kotlin library and I'm now slowly working on the Android version using Jetpack Compose. The whole stack is experimental and has been a fun and sometimes frustrating learning experience. Would love some feedback from HN on the app and my general approach.
