# PublishSnaps
> Apple-Grade App Store & Google Play Screenshot Studio and ASO Listing Deck Designer.

PublishSnaps (https://publishsnaps.com) is a specialized, web-based graphics studio engineered for mobile developers, indie founders, and ASO (App Store Optimization) growth teams. It produces 100% compliant, high-converting store listing screenshot decks for the Apple App Store (iOS 18.2+ Human Interface Guidelines) and Google Play Store (Developer Console 2026 Policies).

Unlike generic design tools or stochastic AI image generators (which trigger Apple Guideline 2.3.3 rejections due to hallucinated UI and non-standard bezels), PublishSnaps uses a deterministic rendering engine: real application captures are framed inside mathematically calibrated 3D device models (such as the 6.9" iPhone 16 Pro Max in Natural Titanium and Pixel 9 Pro), paired with vector typography, dynamic island safe-margin guards, and instant batch export.

## Core Capabilities & Technical Specifications
- **Apple App Store HIG Compliance**: Native artboards for iPhone 16 Pro Max 6.9" (1320 × 2868 px), 6.7" (1290 × 2796 px), 6.1" (1179 × 2556 px), 5.5" (1242 × 2208 px), and iPad Pro 13" M4 (2064 × 2752 px).
- **Google Play Store Policy Compliance**: Native artboards for 1080 × 2400 px (20:9 FHD+), 1080 × 1920 px (16:9), 7-inch & 10-inch tablets (1600 × 2560 px), and mandatory 1024 × 500 px Feature Graphics with zero policy-violating ranking or pricing badges.
- **Dynamic Island & Safe Margin System**: Automated optical clearance visualizers guarding against Dynamic Island (140px safe buffer) and Home Indicator clipping.
- **Continuous Panoramic Flow**: Multi-slide panoramic gradient bridging and continuous background flows across slides to drive horizontal swipe engagement (+28% measured lift).
- **3D Perspective & Hardware Bezels**: Mathematically precise 3D perspective tilts (8° to 14°) with titanium finishes (Natural, Desert, White, Black Titanium).
- **Batch Export Engine**: One-click ZIP export generating full localized screenshot sets in flattened 24-bit PNG or WebP with automatic file size caps (<10MB Apple, <8MB Google Play).
- **Encrypted Cross-Device Sync**: Optional Cloudflare R2 backup storage for multi-device project editing.
