LastApp.ai

What It Is

LastApp.ai is a prompt-driven app builder from LastApp Inc. You describe an app in plain language and it generates native code for iOS and Android, and a React app for the web. The home page puts it simply: "Create native iOS, Android and Web apps from one prompt." Its native-apps page calls itself "The #1 AI-Powered Native App Builder," a ranking the company claims without citing a source. The native-apps page also carries a use-case section that names five audiences: startups and entrepreneurs, small business owners, product managers, enterprise teams and agencies and consultants.

The pitch is aimed at people who want the result of a mobile development team without one: startup founders, small business owners, product managers prototyping features, enterprise teams with internal tool backlogs and agencies. It is also the sort of tool that appeals to developers who want generated code they can read and extend.

What You Build and How

The prompt editor. The home page opens with a text box, "What would you like to make?", and a Create New App button. You can attach files, and an upload dialog accepts images (PNG, JPG, JPEG), audio (MP3, WAV, M4A) and video (MP4, MOV), with the advice to name files by function, such as app_logo.png or hero_image.jpg. A row of starter ideas shows the range: Photo Sharing, Cartoonify, AI Astrology, Calories Tracker, Micro Blog, Tennis Coach, AI Constitution, Dating App, Set Card Game and Rock Paper Scissors.

The four-step flow. The native-apps page frames it as "From Idea to App Store in 4 Simple Steps":

1. Describe your app in natural language, including features, user flows and functionality.
2. The AI generates "production-ready Swift and Kotlin code with complete UI and backend."
3. Preview and customize in real-time simulators, refining by describing changes "or editing code directly."
4. Deploy to the stores: export your code and use guided submission to the App Store and Google Play.

What is generated. The FAQ says LastApp.ai "helps build complete, production-ready, native iOS and Android apps end-to-end using simple prompts," covering "frontend, backend infrastructure, integrations, testing, and app-store-ready builds." The capabilities list in the footer names Native Apps, Server Provisioning, Real Simulator, Automated Testing, Release to App Store and Smart Integrations.

Truly native. The company is explicit about the stack. iOS apps are 100% native Swift with a pure Swift codebase, SwiftUI and UIKit support, Apple Human Interface Guidelines compliance and full iOS SDK access. Android apps are 100% native Kotlin with a pure Kotlin codebase, Jetpack Compose support, Material Design compliance and full Android SDK access. Web apps use React 18+ with hooks and responsive design, and the page adds that they are Progressive Web App ready and SEO optimized. The FAQ adds "no React Native, Flutter, or other cross-platform frameworks," and that both iOS and Android versions are built at the same time from a single project. Platform-specific features are supported; the example given is Siri integration on iOS.

Device features. The FAQ's iOS list is long: Widgets, the AppGroups capability, Siri and Shortcuts, phone, SMS and FaceTime, local notifications, Face ID and Keychain, Sign in with Apple, the share sheet, AVKit (AirPlay, picture-in-picture), CoreMotion, Bluetooth, Location Services and MapKit, background processing, HealthKit, calendar integration, SpriteKit and SceneKit, haptics, Dynamic Type, VisionKit, Spotlight, ARKit and document scanning. The Android list covers widgets, Google Assistant, NFC, Wi-Fi and hotspot, Bluetooth, microphone, storage, IR transmission, alternate keyboards, screen capture and recording, streaming media, sensors (accelerometer, gyroscope, GPS), background processing, location, notifications, GPU rendering, biometrics, Google Autofill, privacy controls, screen mirroring and themes. The capabilities grid adds Apple Watch, Apple Pay, Wallet and GameKit on iOS and Google Pay on Android. The page also promises 60fps animations, instant launch times, optimal battery use and smaller installs than cross-platform builds.

Importing and rescuing existing apps. The home page lets you "Import Project": upload an app zip, a GitHub project or a vibecoded build to Copilot for "expert refinement, fixes, and launch support." Android or iOS project imports are supported, and sample sources shown include Color Way, Budgetly and GPS Stone on iOS and Now in Android on Android. LastApp Copilot is described as "a premium build experience with pro human support," and the solutions menu sets it beside AI Self-Service and an Enterprise offer, so there is a do-it-yourself route and a route with people on the vendor's side.

Preview and testing. The create flow includes an iOS preview with device OS version, dark mode and a screenshot button, and a QR code to download the Android build to a phone.

Code ownership. Under "Full Code Ownership," the native-apps page says "Export clean, well written source code. No vendor lock-in, ever," with clean architecture patterns, comprehensive documentation, a customizable codebase and 100% code ownership. Its comparison table lists "Full Export" under code ownership. James C., a senior iOS developer quoted on the page, says he took the generated code and extended it himself: "No lock-in, real ownership."

Integrations. The page claims "300+ Integrations," and the footer lists Smart Integrations and Server Provisioning among the capabilities. One integration shows up by name in the create flow: a Salesforce prompt says that building a Salesforce app requires Salesforce authentication, with an Authenticate button.

The Evidence From the Pages

• Scale claims. The native-apps page shows "10K+ Apps Built," "98% App Store Approval" and "300+ Integrations." The home page says "Over 86,000 Apps Live." Both are the company's own figures.
• Speed claims. The comparison table lists development speed as "Hours to Days," against 3-6 months for traditional development and 1-3 months for cross-platform. The use-case copy promises a "fully functional MVP in days instead of months" and says a small business gets a native app without "$50K+ costs." These are the company's comparisons.
• Pricing. The site publishes no plan names or prices. The native-apps page invites you to "Start free today - no credit card required" with a "Start Building Free" button. The home page's create flow shows a "Continue for $0.99" step that promises building across iOS, Android and the web, updating the app with prompts, and testing and launching it with LastApp, and it uses app credits: when they run out, a message sends you to customer support.
• Testimonials. Three are quoted on the native-apps page: Michael K., a startup founder who went "from idea to App Store in under a week," Sarah L., an enterprise product manager who can "prototype native features without waiting for engineering sprints," and James C., the senior iOS developer who found the Swift code clean.
• Use cases. Beyond founders and small businesses, the page pitches enterprise teams deploying internal tools, field service apps and employee-facing apps without IT bottlenecks, agencies scaling delivery without hiring, and developers who want to ship mobile apps without learning Swift or Kotlin.

Who It Suits and Who It Does Not

LastApp.ai suits a founder who needs a native iOS and Android MVP and is comfortable describing it in words, a product manager who wants a real-device prototype and an agency that wants more delivery capacity. It is also an option for developers who want generated Swift or Kotlin they can take over. The Copilot import path suits a team holding a half-working AI-generated app that needs fixes and a store launch.

It is a poorer fit for someone who wants a visual canvas, because the editor here is a prompt box and a simulator. The promise of 98% approval and production-ready output remains the company's own claim, so a regulated product should plan on human review of generated code. Budgeting starts from the free start and the "Continue for $0.99" step in the create flow rather than a published plan table.
