Features

Everything you need to go from idea to shipped app.

  1. 1.

    Describe any app

    A sentence is the whole brief. d0 asks what it needs to know, writes native SwiftUI, and compiles it on a real Mac so what comes back is the app running rather than a picture of one.

  2. 2.

    Accounts and data, without a serverPlus

    Your app gets somewhere to keep things and a way to sync them across devices, with Sign in with Apple when it needs accounts. d0 hosts the store and writes the Swift that talks to it, so there is nothing to deploy and nothing to run.

  3. 3.

    Charge for itPlus

    Subscriptions and one-off unlocks through Superwall, so you change prices and paywalls without shipping an update. d0 places the paywall where people are already getting value, rather than on launch, before anyone has a reason to pay.

  4. 4.

    Ship to the App StorePlus

    See who you would be landing next to before you submit, and catch what would get you rejected while it is still cheap to fix. Every render photographs your screens at App Store dimensions, draws an icon, and drafts the title, subtitle and keywords from phrases Apple actually returns results for.

  5. 5.

    Marketing on autopilot

    The app you built becomes the app Directd markets: real competitors with real rating counts, video ideas grounded in your reviews, and creators ranked on views per post rather than followers.

FAQs

Everything you need to know about building with d0.

  • A builder for iOS apps. You describe the app in a sentence, d0 writes the SwiftUI, compiles it on a real Mac and photographs every screen, so what you get back is the app running rather than a picture of one.

  • Two things. It builds native SwiftUI rather than a web page in a shell, which is the single most common reason Apple rejects an app. And it is joined to Directd, so the same account that built the app researches its competitors, writes the video ideas and finds creators to film them.

  • Consumer iOS apps that do one job: trackers, journals, planners, calculators, tools. They can keep data in sync across devices, sign people in with Apple, and charge for subscriptions or one-off unlocks. Games are out of scope. It is deliberately narrow, because an app that does one job is the only kind that can be described in a sentence or marketed in a video.

  • It connects to Superwall to run your paywalls and pricing, to App Store Connect to write your listing and read installs, and to TikTok for posting. None of them is needed to build.

  • Yes, and it is a side effect rather than a feature. Every render photographs your screens at 1206 by 2622, which is already an App Store screenshot. It also draws an app icon and drafts your title, subtitle and keyword field from phrases Apple actually returns results for.

  • There is a free allowance to build with, then $20 a month, or $13 a month paid yearly. One subscription covers d0 and Directd together: building, editing and running your app on a real iPhone all draw from the same allowance.

  • No. You describe what you want and argue with the result in plain language. The Swift is there if you want to read it, and you never have to.
