Appto is a Mac app for creating and running iPhone apps with Claude Code or Codex, from niche research and SwiftUI development to App Store launch and analytics.
Appto is a Mac-based application factory for taking iPhone apps from an idea to App Store release and ongoing maintenance. It combines a workspace for multiple apps with Claude Code or Codex agents, showing each app's phase, the selected app, and its agent conversation in one window.
The workflow covers niche validation, concept and interface development, SwiftUI coding, simulator checks, monetization setup, localized store assets, App Store Connect preparation, and post-launch analytics. Users approve the important choices and any action that writes to App Store Connect or costs money, while the generated projects remain available in Xcode and the user's repositories.
Appto evaluates niches using App Store and Google Play signals, including chart positions, competitor complaints, Android installs, name availability, and potential App Review rule 4.3 risk. Each check can be opened with its supporting evidence.
The agent proposes an app concept, name, and core loop, checks similarity to the user's existing apps before coding, then creates a SwiftUI project and tests each screen in the simulator. It can identify and fix issues found during the walkthrough.
Users can compare two or three design directions, interactive mockups, light and dark themes, rotation, purchase flows, and offline behavior before selecting a direction. Steps can be undone with one button.
Appto creates alternative onboarding and paywall variants, prepares StoreKit 2 subscriptions, and can compare variant performance. Service credentials such as RevenueCat keys are entered in the app and stored in the Mac keychain.
The app prepares iPhone and iPad screenshot sets in 39 languages, localized names, subtitles, keywords, icons, privacy information, and a page score out of 100. It also shows text limits and a task list for the store page.
Appto uploads builds and prepares App Store Connect data, then tracks Apple-reported downloads, proceeds, purchases, ratings, and countries after release. It can draft review replies, flag a new poor rating, and organize improvement suggestions for today, this week, and this month.
Use the niche dossier to compare demand, existing app performance, competitor complaints, naming availability, and App Review risk before committing engineering time. A user-provided idea can also be checked before development.
Review several interactive visual directions, approve one, and let the agent turn it into a SwiftUI project while checking screens in the simulator. This suits creators who can make product decisions but do not want to write the implementation themselves.
Prepare a store launch with localized screenshots, metadata, keywords, privacy information, subscriptions, pricing, and a build for App Store Connect. The user retains control of the final submission and release decisions.
Manage a portfolio of apps in parallel, with a separate agent and repository for each app, a shared queue for decisions, and one view of downloads and proceeds. Existing apps released before Appto can also be connected for reviews, analytics, and store-page work.
Appto is a Mac application that works with Claude Code on a Claude Pro subscription or Codex on a ChatGPT Plus subscription. It helps manage an iPhone app from niche research through development, App Store preparation, submission, and post-launch work.
The agent writes Swift and SwiftUI in a regular Xcode project. The project stays on your Mac, can be opened and built in Xcode without Appto, and each app has its own private repository in your GitHub account.
You choose the niche or approve the proposed one, select a design direction, choose App Store screenshots and copy, and decide when to submit and release. Appto prepares the build, App Store Connect data, and final checklist, but you press the submission button yourself.
The download supports Macs with Apple silicon or Intel and requires macOS 12.0 or later. After installation, setup checks Xcode, the selected agent, and the Apple account. The first niche can be explored without a subscription; an Apple Developer account is needed for release.
Appto can write support for HealthKit, notifications, widgets, Live Activities, Sign in with Apple, and subscriptions. Apps that need a backend can use Supabase, but the account and server bill remain yours. There is currently no separate retention dashboard, and apps for Apple Watch or widgets require more hands-on management.
ByteAsk is a terminal-first AI coding agent for C and C++ that edits repos and verifies changes with compilers, debuggers, sanitizers, and tests.
CreateOS Sandbox is an isolated compute environment for running code and agent workloads in Firecracker micro-VMs with private networking and SDK, CLI, or MCP control.
GitBot is a local browser workspace for reusable coding bots powered by Claude Code, Codex, or OpenCode, with persistent threads and configurable permissions.
hob is an independent workspace for coding agents, with local control over sessions, terminals, history, routing, and follow-up work.
Manta AI is an autonomous web app testing tool that maps app behavior, catches regressions, and generates tests from a URL, no scripts or selectors needed.
SonOf connects to your repo and PM tool, audits your codebase, and turns approved work into shipped tickets with senior engineering review.
