## What is DiashowDL?

DiashowDL is a professional offline slideshow player and presentation tool for speakers, teachers, exhibitors, and businesses. 

Build a show once and play it anywhere — on your phone, tablet, smart TV, or any display on your local network. No cloud account, no subscription fees, and no internet connection required.

• MOBILE PRESENTER REMOTE
Run the show on a big screen, TV, or projector and control it directly from your phone. Synchronized virtual laser pointer, gestures control and more.

• MULTI-FORMAT MEDIA PLAYER
Mix images, videos, PDF documents, Lottie animations, and embedded HTML/web pages into a single seamless slideshow. Apply professional transition effects, configure Ken Burns pan-and-zoom motion paths and add captions.

• LIVE WIDGET OVERLAYS
Overlay utility widgets on any slide, including clocks, timers, weather status, and custom branding logos. Connect local environmental sensors (BME680, SCD30) over Wi-Fi to monitor temperature, humidity, CO₂, and air quality (IAQ) live on-screen during your presentations.

• BUILD & ORGANIZE OFFLINE
Create new slideshows using a built-in visual editor. Reorder slides, configure custom curves for image transitions, and pack everything into a self-contained DDLZ archive to share, backup, or deploy instantly to external devices.

• DEVELOPER-FRIENDLY & SCRIPTABLE
Shows are defined in Diashow Description Language (DDL) — a lightweight, version-control-friendly declarative format. Drive playback programmatically using a built-in REST API. Open-hardware integration guides and client SDK code examples (Python, Java, Go, Dart, Node.js, and ESP32/Arduino) are available on GitHub.

• TRUE CROSS-PLATFORM
The same DDL show file plays identically on other systems. Perfect for kiosk setups, trade show displays, museum installations, and digital signage.

• Free to download and evaluate: The free tier is fully functional. A single, one-time in-app purchase removes the license reminder slide.

• No analytics, no tracking, and no external servers: Your data and presentations remain entirely on your local hardware.

• Ideal for: keynote speakers, lecturers, event coordinators, photographers, museums, and kiosk operators running custom digital signage on their own hardware.
