I built an AI app to stop me from oversleeping in 22 minutes

Ever since I started "vibe coding, my productivity has gone off the rails. Today, I’m tackling my biggest enemy: the Snooze Button.

I built "Get Up, Genius"; a React Native app that refuses to stop screaming until I physically get out of bed and scan a QR code in my kitchen. The best part? I have little mobile dev experience, and the whole build took exactly 22 minutes using Cursor and Gemini AI.

In this video, I break down the prompt engineering I used to architect the app, the "permission" hurdles I hit, and a live demo of me actually having to use it at 6:00 AM.

Watch me build it in 22 minutes flat.

The "Magic Prompt" I used: "I am building a React Native app with Expo (TypeScript). This is an alarm clock app called 'Run For Your Life'.

Core Feature: The alarm plays a loud sound and cannot be stopped until the user scans a specific barcode (like a toothpaste barcode).

Phase 1 Goal: Please write the code for a simple screen that has:

A big text display showing the current time (digital clock style).

A 'Set Alarm 1 Minute from Now' button (for testing).

When the alarm triggers, it should play a sound and show a 'SCAN TO STOP' button.

Clicking 'SCAN TO STOP' opens the camera.

Please tell me which libraries I need to install for Audio and Camera permissions in Expo, and give me the code for app/index.tsx."

Tools used:

Editor: Cursor (AI Code Editor)
Framework: React Native + Expo
