The best vibe coding tools for mobile development

I explore the best AI-assisted vibe coding tools for mobile development, focusing on how they integrate with Expo and React Native. I demo five simple apps created with these tools to test their capabilities and speed, including a mood logger and a bounce tap game.

If you want to try AI tools that generate mobile apps with minimal coding, this video is for you. I also share honest caveats about limitations and how to test your apps with Expo Go on your phone.

Introduction to vibe coding and AI tools for mobile development

Vibe coding is an AI-driven approach where developers let AI take the lead in writing code, focusing on flow rather than manually coding every line. I cover popular vibe coding tools that generate mobile apps, mostly built on Expo, the leading cross-platform framework.

I emphasize that while these tools are powerful, developers with zero programming experience might struggle with complex apps. For those new to React Native and Expo, I recommend my React Native course to build a solid foundation before diving into vibe coding.

Using Bolt to create an Emoji Mood Logger app

Bolt is a standout vibe coding tool with a strong Expo integration. I start by creating an account and using Bolt’s prompt enhancer, which improves my initial vague prompt into a detailed app specification. The app logs daily moods by tapping emojis, shows a 30-day history, and includes animations.

Bolt quickly generates the app’s code, including layouts, tabs, and utility functions for local storage. I scan a QR code to open the app in Expo Go on my iPhone. The UI looks polished with smooth animations, though the mood history animation had some issues. Bolt allows iterative prompt refinement to improve the app before shipping.

Testing Replit for building a bounce tap game

Replit is another AI tool that supports Expo apps and asks for user approval before generating code. I prompt it to build a bounce tap arcade-style game with continuous bouncing and sound effects. Replit confirms the requirements and installs dependencies before showing the output.

The generated game runs well in a web preview, with sound effects and interactive bouncing. However, Replit builds a web-based app using HTML5 rather than a pure React Native app, which limits native mobile features. Still, it feels robust and suitable for quick prototyping.

Trying a.dev for an AI-powered Expo app game

I test a.dev next, which does not require an account initially. However, I encounter issues with empty prompts and errors until I create an account and start a new chat session. Once working, a.dev generates an Expo app game based on my prompt.

a.dev lacks a prompt enhancer like Bolt, so prompt clarity is important. The tool runs the generation process smoothly after setup. This shows that some vibe coding tools still have rough edges but can produce usable apps with persistence.

Overview of other AI tools relying on Expo

Besides Bolt, Replit, and a.dev, I mention other vibe coding tools like aella, work.app, and makeway DOA. All rely on Expo as their foundation for cross-platform mobile app generation. If you know other AI tools for mobile development, you can share them in the comments for me to check out.

Expo’s ecosystem is key to enabling these AI tools to generate apps that run on iOS and Android devices with minimal manual setup.

How to test generated apps with Expo Go on iPhone

To test the generated apps, you need the Expo Go app installed on your iPhone or Android device. After the AI tool finishes generating the app, it provides a QR code. Scan this code with your phone’s camera to open the app instantly in Expo Go.

This live preview is essential to see the UI, animations, and interactions as intended. While some tools offer web previews, Expo Go provides a more accurate mobile experience.

Tips on prompt enhancement and iterative improvements

Bolt’s enhanced prompt feature is a highlight. It takes a rough prompt and rewrites it into a detailed, clear specification before generating code. This improves the quality of the output and reduces the need for manual fixes.

I recommend iterating on your prompts by refining or adding details and regenerating the app multiple times. This iterative vibe coding approach helps you ship better apps faster.

Challenges and limitations encountered with AI tools

While vibe coding tools are impressive, they have limitations. For example, Bolt’s mood logger had some animation glitches in history view. Replit generated a web-based app instead of a native React Native app due to environment constraints.

Some tools require account creation or have buggy prompt handling. Notifications and native features can be tricky for AI to implement fully. These caveats mean vibe coding is best for simple to moderately complex apps currently.
