A private app studio for Mac

Describe an app. Watch it appear.

Palm turns one sentence into a native SwiftUI iPhone app, an Apple Watch companion and the marketing to launch it: content, press, outreach and ads. The AI runs on your Mac, so your ideas stay yours.

What Palm is

Palm is the first app builder that lives on your Mac. Say what you want, and it writes a real iPhone app, previews it, and prepares everything you need to ship it. Privately.

01 · Describe

Start with a sentence.

No specs, no wireframes. Tell Palm what the app is for, in everyday language, the way you would tell a friend.

  • Pick what you’re launching: a business, a product, something personal or a community
  • Palm plans the screens, the data and the first useful action
  • Every project keeps its own brief, so Palm remembers who the app is for

Describe an idea in everyday language.
A simple home inventory for my family. Let me add rooms and items, attach notes, and quickly find where something is stored.
Build App
The real new-project sheet
Real Swift, written for you
02 · Build

Real Swift. Not a mockup.

Palm writes native SwiftUI and SwiftData, generates the Xcode project and compiles it. If the build fails, it reads the errors and fixes them.

  • Lists with search, add, edit and delete, plus a tab bar and a working Settings screen
  • A repair loop that rebuilds until it compiles, then resumes if you interrupt it
  • Plain project files you can open in Xcode any time. No lock-in
03 · Preview

See it running on a phone.

Palm launches your app in the iOS Simulator and shows it beside the code, in light and dark mode, so you can judge it like a user would.

  • Choose the device and watch the app launch, then refresh after every change
  • Ask for changes in plain English: “add search”, “make it darker”, “add a settings screen”
  • Palm rewrites only the files that need to change

Everything after “it runs”.

Most builders stop at a demo. Palm keeps going: devices, monetisation, review checks and the marketing to launch it.

Build

Native SwiftUI + SwiftData with list, search, edit, delete, tabs and settings generated from your idea.

Extend

Add an Apple Watch app, widgets, push notifications, camera and GPS, maps and an offline sync queue in one tap each.

Monetise

A StoreKit paywall with restore, Terms and Privacy links, plus pricing guidance tuned to the kind of app you made.

Ship

An App Review risk check before you submit, store listing and screenshots copy, and a launch plan that starts the day you publish.

Then launch it

Most app builders stop when the app runs. Palm helps you sell it.

A built app nobody hears about is still a side project. Palm plans the launch alongside the build: positioning, content, press, outreach, ads and a checklist, all from the same idea, all private on your Mac, and nothing goes public until you approve it.

One click

A whole launch kit

Palm drafts a landing page, brand direction, a blog post, Twitter thread and Show HN post, press angles, a pricing recommendation, outreach targets, a launch checklist, ad copy for Meta, Google and Apple, and a five-email onboarding sequence. Export it as a folder or a ZIP.

You stay in charge

Nothing goes out unreviewed

Every draft lands in a review queue where you edit, regenerate, reject, export or approve it. Social tools get drafts only, email is never sent without your confirmation, and Product Hunt copy is handed over for you to publish.

Honest drafts

Evidence versus inference

Each draft says what it was grounded on and what the AI inferred, with a reminder to check claims, names and prices before you use it. Palm is a head start, not an autopilot.

After launch

Keep the momentum

Keyword ideas for your App Store listing, competitor rechecks, ratings and review monitoring, review-request emails, a monthly report and a daily nudge, so launch week is not the only week you market.

Review queue

6 drafts need your decision before they go public.

The real review queue in Palm

Six drafts waiting, each with Edit, Regenerate, Reject, Export and Approve. Approving is always a deliberate click.

Drafts are a starting point. They come from the model running on your Mac, so longer or more specific results need a capable model and a Mac with enough memory. Check every claim before you publish.

Your ideas never leave your Mac.

Palm runs its AI on your machine with Apple Intelligence or a local model through Ollama, and chooses a model that fits your Mac’s memory. There is no account, and no one reads your prompts.

Questions

Good to know.

What does Palm build?

Native SwiftUI iPhone apps with a SwiftData data model, list, search, add, edit and delete screens, a tab bar and a settings screen. It can then add an Apple Watch companion, widgets, push notifications, camera and GPS, maps, offline sync and a StoreKit paywall.

Do I need to know how to code?

No. You describe the app in everyday language and Palm writes the Swift, builds it and opens it in an iPhone preview. You can open the finished project in Xcode whenever you want to go further.

Is Palm private?

Yes. The AI runs on your Mac with Apple Intelligence or a model served locally by Ollama. Your prompts, projects and generated code stay on your Mac. Palm only contacts a service when you connect it, such as App Store Connect.

Does Palm help me market my app?

Yes. Palm drafts a launch kit alongside the build: landing page, brand direction, blog post, Twitter thread, Show HN post, press angles, outreach targets, ad copy and an email sequence. Every draft goes to a review queue, and nothing is published or sent until you approve it. Drafts are starting points from the model on your Mac, so check the details before you use them.

What do I need to run it?

A Mac running macOS 26 with Xcode installed, because Palm builds and previews iPhone apps with Xcode’s tools. 16 GB of memory is recommended so a capable local model runs comfortably; on smaller Macs Palm chooses a smaller model.

How much does it cost?

The Mac app is a free download. You can go through the guided setup and describe your app or site for free. Everything after that, including building, the editor, the marketing studio and the launch kit, needs the one-time $49 Pro unlock, sold through Polar. There is no subscription.

Who owns the apps I make?

You do. Palm claims no rights to the apps, code or marketing material it generates, and you can ship them commercially. You are responsible for reviewing the code and for meeting App Store Review Guidelines.

Your turn

Bring the half-formed idea.
