iOS-1K-Mobile-UI-Dataset
Overview
iOS-1K-Mobile-UI-Dataset is a curated dataset of 1,000 real-world iOS mobile UI screens collected from diverse application categories available on the Apple App Store.
Each screen is paired with human-validated structured JSON ground truth annotations, enabling research in UI understanding, layout analysis, and multimodal modeling.
The dataset includes:
- Simple layouts (e.g., login, onboarding screens)
- Visually dense interfaces (e.g., feeds, checkout flows)
- Structured UI element annotations
- Bounding boxes for UI components
- Element type labels
- Clickability attributes
- Text content for text-bearing elements

Metadata Format
The metadata.csv file provides mapping between images and annotations:
| screen_id | image_file | annotation_file |
|---|---|---|
| 0001 | images/0001.png | annotations/0001.json |
| 0002 | images/0002.png | annotations/0002.json |
Example Screen
Below is a sample Eleven Reader App’s login screen from the Dataset :
Annotation Format
Each JSON annotation follows a structured schema:
{
"screen_id": "0001",
"elements": [
{
"id": 1,
"type": "button",
"bbox": [x, y, width, height],
"text": "Login",
"clickable": true
}
]
}
Each element includes:
type: UI component category (e.g., button, text, image)bbox: Bounding box coordinatestext: Visible text content (if applicable)clickable: Boolean interaction label
Intended Use Cases
This dataset is designed for:
- Mobile UI understanding
- Layout parsing and structural analysis
- UI element detection
- Vision–language modeling
- Multimodal LLM grounding
- Autonomous UI agent research
Download Instructions
You can download the dataset using the Hugging Face Hub:
from huggingface_hub import snapshot_download
snapshot_download(
repo_id="atharparvezce/iOS-1K-Mobile-UI-Dataset",
repo_type="dataset",
local_dir="./iOS-1K-Mobile-UI-Dataset"
)
Limitations
- Covers only iOS platform interfaces
- Contains 1,000 screens in the current release
- Category distribution reflects App Store sampling
- UI copyrights remain with original application developers
Future Work
We are actively working on extending the iOS-1K-Mobile-UI-Dataset with:
- Additional UI screens across more application categories
- Increased dataset scale beyond 1,000 screens
- More detailed attribute-level annotations
- Expanded layout complexity coverage
- Benchmark splits for training and evaluation
Our goal is to develop this into a larger benchmark for mobile UI understanding and multimodal research.
