These days I do not use Expo when building apps. Building native iOS apps with SwiftUI is easy, fast, and standard. Tools like Expo were born from the need to support many platforms with limited resources, but now that coding agents are smart enough, building each platform separately has become easy enough that much of that need is disappearing.
The apps I have been building for my own use lately all share one thing in common: their purpose is to gather the right data and hand it to ChatGPT. They collect the necessary inputs, turn them into context, and pass them into ChatGPT or Claude as the opening turn of a conversation. Then the model gives a remarkably good answer.
Take my app Oh My Zwift as an example. It gathers course information for bike races along with the key metrics of both me and my competitors. Then I ask for my expected placement and the best strategy to win. The resulting actions are practical enough to be immediately usable.
If the business model of the last era was about monopolizing and assetizing data, perhaps the more natural direction now is to return data ownership to the individual while making the technology more open and easier to exchange. LLMs answer according to the inputs we give them.
