iOS App Builder Online
for iPhone Apps
Fastshot is a free iOS app builder that turns a description into a real native iPhone app. Build iOS app online in minutes — no Xcode, no Mac, no Swift. As a no code iOS app builder powered by AI, it generates production-ready React Native + Expo code and builds signed IPA files in the cloud.
What is an iOS App Builder?
An iOS app builder is a tool that lets you create native iPhone apps without manually writing Swift, configuring Xcode, or owning a Mac. The classic workflow demands a paid Apple developer account, an up-to-date macOS machine, hours of provisioning-profile setup, and weeks learning Swift or SwiftUI. An online iOS app builder collapses that entire pipeline into a browser tab.
Fastshot is a no code iOS app builder powered by AI. You describe the app you want in plain English — screens, data, flows, integrations — and Fastshot generates a real React Native + Expo project, then builds a signed IPA file in the cloud. The result is a genuine native iPhone app, not a web view, that runs as a real native app on iOS.
If you've been searching for a free iOS app builder that works without Xcode, an iPhone app builder for non-developers, or simply a way to create iPhone app without coding, the workflow is the same: describe, preview on your phone, and ship. You can create iOS app without Xcode entirely — Fastshot handles the build pipeline, code signing, and TestFlight-ready output for you.
For the Android side, Fastshot also acts as an [APK builder for Android](/apk-builder). One description, one codebase, native iOS and native Android — and you own the source code from day one.
How to Create an iPhone App Without Coding
Describe Your iPhone App
Tell Fastshot what your iPhone app should do — screens, features, data, integrations. No code, no diagrams, no Xcode project setup. Plain English is enough for the iOS app creator to generate the structure.
AI Writes the iOS Code
The online iOS app builder generates a complete React Native + Expo project tailored to your description: native iOS navigation, screens, state management, and Supabase backend integration if you need it.
Cloud Builds Your IPA
Fastshot builds your iOS app online — compiles the project, signs the IPA file, and runs the full Apple toolchain in the cloud. No Mac, no Xcode, no provisioning headaches. The signed IPA is ready for TestFlight or the App Store.
Preview, Export, and Ship
Scan a QR code to preview the iPhone app on your real device. Iterate quickly, then export the signed IPA file and submit to TestFlight or the App Store directly. The full source code is yours.
iPhone App Builder Features
Free iOS App Builder Tier
Start as a free iOS app builder — no credit card to begin. Generate code, preview on your phone, and iterate as much as you need. Upgrade only when you're ready to publish to the App Store.
No Xcode, No Mac
Create iOS app without Xcode and without owning a Mac. Cloud builds run the entire Apple toolchain remotely — you only need a browser. This is what makes Fastshot a real online iOS app builder.
Native iPhone Output
Output is genuine native iOS, not a web wrapper. The app maker for iPhone produces React Native code that compiles to a real native binary, with full access to camera, GPS, push notifications, and biometrics.
Signed IPA Files
Every build produces a signed IPA file ready for TestFlight or App Store submission. Code signing, provisioning profiles, and entitlements are handled automatically by the cloud build.
iPhone + iPad Support
Fastshot builds universal iOS apps — your iPhone app runs natively on iPad too, with adaptive layouts. One codebase, both form factors.
You Own the Source Code
Export the complete React Native + Expo source any time. No vendor lock-in. Modify the code yourself, hand it to a developer, or keep iterating with Fastshot — your call.
