CatDoes alternative
A CatDoes alternative in native Swift
CatDoes builds mobile apps in React Native and Expo, and publishing to the App Store starts on its Starter plan. Borel is the alternative for a native iPhone app: it writes Swift with SwiftUI, runs every build in the iOS Simulator in your browser, and includes App Store publishing on Pro, from $20 a month.

CatDoes
Who is CatDoes for?
CatDoes is an AI agent that builds what you describe, for the web and for phones, and every project comes with a database, sign-in and file storage. It's a fit for someone who wants one app on iPhone and Android.
The iPhone question
Where does CatDoes stop for an iPhone app?
Its mobile apps are React Native with Expo. App Store and Google Play publishing come with the Starter plan and above, and the Free and Core plans deploy to the web.
Downloading your code starts on Plus, a plan above Starter, which itself costs $42 a month. On Borel, publishing comes with Pro and the code is yours to download on any plan.
Borel
What Borel does differently
Native Swift and SwiftUI
Borel writes the app in Apple's own language and framework and compiles it with Xcode on its own Mac.
Publishing on the first paid plan
App Store publishing comes with Pro, from $20 a month. Borel builds, signs and uploads it for you.
Your code on any plan
Download the Swift project, with an XcodeGen project.yml that opens in Xcode, even on the free plan.

Frequently asked questions
No. It writes a new Swift app from what you tell it, rather than converting React Native code.
Yes. Accounts, a cloud database, file storage and Borel AI come with every app, run by Borel.
SwiftUI is the framework Apple builds its own apps with, so navigation, lists, sheets and gestures behave the way iPhone users expect, and Face ID, the camera and Apple Maps are called directly rather than through a bridge.
Yes. Download the Swift project on any plan, the free one included, and open it in Xcode. A published app sits under your own App Store Connect account.
No. Borel makes native iPhone apps, and the same app runs on iPad. For one app on both, a React Native builder fits better.
In Apple's iOS Simulator on Borel's Mac, streamed into your browser. It's free for everyone, and on Pro Borel Companion installs it on your iPhone.
