Truly Simple Slide Deck

Create slide decks and presentations by writing what you want to say and styling it with Markdown. Adjust the colors, fonts, and alignments, add images and videos.
Present your slide show within the app and make use of the presenter view, which contains speaker’s notes, the current slide, and a next slide thumbnail, or export your project as a PDF, webpage, or as ultra-portable Markdown text.
There’s an in-app purchase that allows for customization of the colors and fonts, and for the saving of custom themes, but all other features are available in free version.
Features:
• Create, edit, and share slide decks
• Present your slideshow within the app, benefitting from speaker’s notes, next-slide previews, and adjustable auto-advance options
• Use pre-built templates or craft your own slide layouts
• Share your projects as PDFs, HTML, or Markdown text files
• Use one of the pre-built themes or customize your colors and fonts, and save your own themes (requires one-time Pro upgrade)
• macOS and iOS apps available (sync projects between your devices by saving them to iCloud)
