The Problem Space¶

⏎

I’ve tracked my personal finances for years, but none of the products I tried quite fit how I wanted to manage them. So I started building my own: Plusss, a native iOS finance app.

I love building products. Plusss is my playground for trying ideas and concepts, using LLMs and agentic workflows to turn them into working SwiftUI prototypes.

From Idea to SwiftUI with AI¶

⏎

I use LLMs and agentic workflows to build the prototype in SwiftUI. I guide what to build, try the result in Xcode and on device, then iterate on the behavior and interface.

The value is being able to explore native interactions in a working app and keep refining them as I use it.

Exploring the App in Working Software¶

⏎

Wallets, budgets and trips give me a range of screens and states to experiment with, from charts and spending summaries to navigation and native controls.

Trying the Interaction Details¶

⏎

The transaction flow lets me explore amount entry, category selection and related settings in a real native interface.
