Weather Today App — How to Create Your Own Dynamic Weather App With Rosebud AI (Using Nano Banana Pro)

A step-by-step guide to building a personalized weather experience with no coding.

Introduction: Build Your Own Weather App Without Coding

Checking the weather shouldn’t be boring — and now, with Rosebud AI’s game-maker tools and Nano Banana Pro, you can create a fully personalized, interactive weather app that feels like a mini-game.

This guide shows you exactly how to make a weather app, even if you’ve never coded before.
We’ll use:

• Rosebud AI (World Builder)
• Nano Banana Pro (for UI + quick 3D assets)
• Simple logic blocks (no programming required)

Why Build a Weather App With Rosebud AI?

Most weather apps are static and generic. Wiith Rosebud AI, you can:

• Turn today’s weather into a 3D scene (rain, snow, sun, fog).
• Add interactions (tap a cloud, swipe wind).
• Create your own characters that announce the weather forecast.
• Build a unique UI using Nano Banana Pro’s visual components.
• Publish it as a mini-web app or shareable game.

This is the best AI tool right now for mixing data + UI + interaction without touching code. Take a loot at my example : https://rosebud.ai/p/08a522ec-ac7c-49ad-9f25-ca0a1da88c1e

Step-By-Step: Build Your “Weather Today App”

1. Open Rosebud AI and Start a New World

Go to rosebud.ai → Create → Start from scratch.

Prompt example:

“Create a simple 3D environment for a weather app dashboard. Minimalist style. Add a floating panel for temperature, wind, humidity, and an avatar character.”

This gives you the base “game” where the weather will be displayed.

2. Use Nano Banana Pro to Generate Your UI Components

Nano Banana Pro helps you create:

• Icons (sun, rain, cloud, snow)
• Cute backgrounds and city visual

Example: We are using the prompt of Pavol Rusnak (https://x.com/PavolRusnak/status/1995165498774802607)

Export the assets → drag them into your Rosebud world.

3. Add Real Weather Data (Free API)

Use any free weather API, for example:

Open-Meteo API (100% free)
https://open-meteo.com/

In Rosebud AI, add a simple logic block:

• Fetch latitude/longitude
• Retrieve current weather
• Update your UI panel
• Change the 3D scene depending on the result

Rosebud handles the logic visually → no coding needed.

4. Make the Weather Truly Dynamic

This is where it becomes fun.

Add conditions:

☀️ Sunny

• Bright light
• Warm color grading

🌧 Rain

• Add rain particles
• Wet ground reflections

🌫 Fog

• Add volumetric fog
• Lower visibility

⛄ Or...

‍

In Rosebud AI, you add Nano Banana assets for each weather condition and ask Rosie, our agent, to display them depending on the current weather.

“If weather = rain, activate rain particle system and change skybox to cloudy.”

The system builds it automatically.

5. Personalize the App

Examples you can add:

• A mascot (cute animal, robot, anime guide).
• Daily motivational message.
• Outfit recommendations (coat, umbrella, gym clothes).
• Weather-based music or ambiance SFX.
• A mini-game tied to the weather (“Catch the snowflakes,” “Tap the sunshine,” etc.)

This makes it feel more like a personal AI world than a standard app.

6. Export or Share Your Weather App

With Rosebud you can export as:

• A mini-web app
• A shareable link
• A playable 3D scene
• An embeddable widget for your website

Now you’ve created your own Weather Today App from scratch — no code, just AI tools.
