# Fun Vibe-coding Mobile Apps - 2026-02-13 Source: https://www.youtube.com/watch?v=Bshw3dSFIto Recap page: https://rapidrecap.app/video/Bshw3dSFIto Generated: 2026-02-13T21:07:21.115+00:00 --- ## Quick Overview The presenter successfully used Rork, an AI-powered mobile app builder leveraging React Native and Expo, to create a complex mobile app prototype in under 15 minutes, demonstrating its speed and power, despite noting that the AI-generated code needed minor adjustments, particularly regarding proprietary Apple features like iCloud storage. **Key Points:** - Rork built a complex, cross-platform mobile app prototype in under 15 minutes using only natural language prompts. - The generated app used React Native with Expo, which allows simultaneous building for Android and iOS. - The presenter noted that the AI-generated code was generally good but required minor corrections for proprietary features like Apple's iCloud storage. - The presenter mentioned that while the code is fast to generate, complex apps might require manual iteration or refinement. - The presenter plans to share the generated code on GitHub, encouraging others to experiment with the tool, which costs $20/month for the Pro tier. - The presenter ultimately fixed the minor bug in the generated code without needing to look at the code itself, relying on the AI feedback loop. - The TriLog app, the example project, tracks mood, energy, and activities in a visual grid format. ![Screenshot at 00:00: The initial Rork homepage displaying the prompt: "Build native mobile apps, fast." and the input field: "Describe the mobile app you want to build."](https://ss.rapidrecap.app/screens/Bshw3dSFIto/00-00-00.jpg) **Context:** The video features a demonstration of Rork, an AI tool designed to build native mobile applications quickly by interpreting natural language descriptions. The presenter, Joe, is showing how fast the tool is by building an app similar to his own complex habit-tracking app, TriLog, which he developed over 20 years using traditional coding methods. The demonstration highlights Rork's ability to generate cross-platform code using React Native and Expo, and the presenter interacts with the AI feedback loop to refine the generated application. ## Detailed Analysis The presenter demonstrates Rork's capability to generate a complex mobile application prototype based on a natural language description, completing the initial build in under 15 minutes. The app being built is a calendar/tracker similar to the presenter's own complex app, TriLog. Rork utilizes AI to build cross-platform apps using React Native and Expo. After the initial generation, the presenter noted that while the process was fast, some proprietary features, like iCloud integration, required manual tweaks, although the AI feedback loop helped resolve issues without the presenter needing to manually edit the generated code extensively. The pricing model is revealed, showing a $20/month Pro plan for private projects and features like a code editor and GitHub integration, while the Free tier allows for public projects. The presenter encourages viewers to try the tool, emphasizing that the speed of iteration is revolutionary compared to traditional development timelines, which took him years for a similar app. ### Rork Platform Overview - Build native mobile apps, fast. - Rork builds complete, cross-platform mobile apps using AI and Expo (React Native). - Rork Max is a coming soon feature. ### TriLog App Features - Track mood, energy, and daily patterns in seconds. - Features include: Quick Track (2-5 seconds entry), See everything at once (visual grid), Weather & more, Light & dark modes, Data stays yours (locally stored). ### Visual Grid Details - Columns = Days (Sun-Sat) - Rows = Hours (Midnight to Midnight) - Colored Blocks show activities (blue=sleep, red=work, green=exercise, purple=leisure). ### Pro Features - Pomodoro Timer - Custom Trackers (water intake, medication, etc.) - Quick Track - Morning Routine. ### Pricing - Free ($0/mo for public projects) - Pro ($20/mo, includes 100 credits, code editor, GitHub integration) - Max ($200/mo, includes 1K credits, everything in Pro + Bank/Realty chat support). ### Development Workflow - Prompt Rork with app description -> AI generates code -> Preview in browser/phone (via QR code) -> Iterate on code/prompt -> Publish to App Store (requires Apple developer license, $99/year). ### Code Quality Discussion - AI-generated code is powerful, but proprietary/complex features (like iCloud sync) might need manual fixes or careful prompting; the iteration loop is fast, making it a revolutionary development process. ![Screenshot at 00:00: The initial Rork homepage displaying the prompt: "Build native mobile apps, fast." and the input field: "Describe the mobile app you want to build."](https://ss.rapidrecap.app/screens/Bshw3dSFIto/00-00-00.jpg) ![Screenshot at 01:25: The TriLog app landing page detailing features like 'Track your day in seconds' and showcasing mobile app screens.](https://ss.rapidrecap.app/screens/Bshw3dSFIto/00-01-25.jpg) ![Screenshot at 02:19: Slide detailing the core components of TriLog: Mood \(5 states\), Energy \(5 vitality levels\), and Activity \(Sleep, Work, Exercise, etc.\).](https://ss.rapidrecap.app/screens/Bshw3dSFIto/00-02-19.jpg) ![Screenshot at 03:09: Slide explaining 'The Visual Grid' structure: 7-Day Columns \(Days\), Rows \(Hours\), Colored Blocks for activities, and indicators for Mood/Energy, Weather, and Moon Phases.](https://ss.rapidrecap.app/screens/Bshw3dSFIto/00-03-09.jpg) ![Screenshot at 10:30: The Simple, transparent pricing modal showing Free \($0\), Pro \($20/mo\), and Max \($200/mo\) tiers.](https://ss.rapidrecap.app/screens/Bshw3dSFIto/00-10-30.jpg)
