Make APK Files
From Your App Idea
Fastshot is an AI-powered APK maker that turns your app concept into a downloadable, installable Android package. No programming, no Android Studio, no complexity.
What is an APK Maker?
An APK maker is a tool that helps you create Android application packages without deep technical expertise. While a traditional APK builder focuses on compiling existing code, an APK maker takes a higher-level approach, helping you create the entire app from concept to installable package.
Most APK makers on the market are drag-and-drop builders with limited capabilities, producing cookie-cutter apps that lack the polish and performance of natively coded applications. They often lock you into proprietary platforms and charge recurring fees for hosting.
Fastshot redefines what an APK maker can be. Instead of dragging widgets onto a canvas, you describe your app in natural language. The AI generates real React Native + Expo code, complete with proper architecture, navigation, state management, and a Supabase backend.
The result is a professional-grade APK that performs like a hand-coded native app, not a templated web wrapper. And you walk away with the complete source code, giving you the freedom to extend, customize, or hand off the project to any developer. (For the underlying workflow — the 5-step prompt-to-binary loop the AI runs through — see our step-by-step guide to building a mobile app with AI. Developers can also inspect the React Native code the AI generates for a sample of the actual output.)
How the APK Maker Works
Share Your App Vision
Describe the app you want to create. Include details about screens, user flows, features, and visual preferences. The more detail, the better the result.
AI Creates Your App
Fastshot generates a full React Native + Expo project with components, styles, navigation, and backend connections tailored to your description.
Test on Any Android Device
Preview the app instantly on your phone using Expo Go. Test every feature and screen before committing to a production build.
Download Your APK
Trigger a cloud build to produce a signed APK file. Download it, share it with testers, or distribute it however you like.
What Makes Fastshot the Best APK Maker
AI-Driven Code Generation
Unlike drag-and-drop builders, Fastshot generates actual source code. This means better performance, more flexibility, and no platform limitations.
Professional-Grade Output
Generated apps use proper architecture patterns, efficient state management, and optimized rendering. Your APK performs like a professionally built app.
Complete Source Code
Every APK comes with the full React Native + Expo source code. Inspect it, modify it, or hand it to a development team for further work.
Backend Built In
Ask for a backend and Fastshot connects Supabase, giving you user authentication, database storage and file storage without setting it up by hand.
Iterative Refinement
Not satisfied with the first version? Describe changes in plain English and Fastshot will update the code and rebuild your APK.
Cross-Platform Bonus
Your APK project is also an iOS project. When you are ready, generate an IPA from the same codebase and ship to the App Store too.
Fastshot vs Other APK Makers
| Capability | Fastshot | Typical APK Makers |
|---|---|---|
| App creation method | Natural language AI | Drag-and-drop templates |
| Output quality | Native React Native code | Web wrapper or hybrid |
| Source code access | Full ownership | Limited or locked |
| Backend included | Supabase (auth, database, storage) | Basic or paid add-on |
| Customizability | Unlimited, edit code directly | Limited to available widgets |
| iOS support | Same codebase | Separate project or unavailable |
APK Maker FAQ
Fastshot uses AI to generate real React Native source code instead of assembling templates. This produces higher quality apps with better performance, full customizability, and no vendor lock-in.
ChatGPT can write pieces of code, but it cannot run, build, sign or publish an app — you would still assemble the project, set up Android Studio or Xcode, and handle signing yourself. Fastshot writes the whole React Native + Expo app from your description, lets you test it on your phone with Expo Go, then builds the signed APK or AAB (and the iOS version) in the cloud.
Yes. You describe your app in plain English, and Fastshot handles all the technical work including code generation, building, and signing the APK.
Yes. Fastshot writes your app once in React Native + Expo, and the same project builds for both platforms: an APK or AAB for Android, and a TestFlight build or an unsigned IPA for iOS. See the IPA generator for the iPhone side.
Yes. You can describe changes to Fastshot and regenerate the APK, or edit the source code directly if you prefer hands-on modifications.
Yes. Fastshot generates clean, transparent source code with no hidden malware or tracking. You can review every line of code before building the APK.
Yes. You own the source code and the app. In-app purchases and subscriptions are built in: connect RevenueCat or Adapty in the Monetization tab and ask the AI to add them to your app. Since the full React Native code is yours, you can also add other models yourself.
Create a Google Play developer account (a one-time $25 fee) and upload the first build of a new app by hand in Play Console, as Google requires: build once without a Google Play upload and download the AAB from the build card. Then add your Google Play service account key in Fastshot and choose a track — internal testing, closed testing, open testing or production. Fastshot builds the AAB and uploads it for you; if the app is still a draft in Play Console, the build arrives as a draft release you roll out there. New personal developer accounts must first run a closed test with at least 12 testers for 14 days before Google grants production access. More in the AAB builder guide.
Simple apps can go from description to downloadable APK in under 15 minutes. More complex apps may take longer for generation and building but are still dramatically faster than traditional development.
