We’re excited to introduce Social Sharing in TestFlight Beta 13! Now you can share your sailing adventures on social media with beautifully designed maritime postcards.

Nautical Chart-Style Sailing Postcards

Generate Shareable Images from Your Logbook

Generate 1080×1080px shareable images from any logbook entry, styled to look like vintage nautical charts:

  • Filtered hero image background with 35% opacity for that aged chart aesthetic
  • GPS track overlay showing your actual route with departure and arrival markers
  • Metadata boxes featuring departure/arrival ports, distance, and weather conditions
  • Nautical styling including compass rose, coordinates, and navy/brass color palette

Share Sailing Photos on iPhone, iPad, and Mac

Share your postcards instantly using the native iOS share sheet:

  • Send via Messages, Mail, or your favorite social apps
  • Save to Files or Photos
  • Works seamlessly across iPhone, iPad, and Mac

Graceful Fallbacks

The postcard generator works even when you don’t have:

  • A hero image (shows navy gradient instead)
  • GPS track data (focuses on metadata)
  • All fields filled (adapts to available information)

Technical Details

This feature uses SwiftUI’s ImageRenderer at 3x scale for crisp 1080px images, with CoreImage filters for the nautical chart aesthetic. The GPS track is rendered on a Canvas with proper coordinate transformations.

Coming Next

Stay tuned for upcoming postcard style presets like “Technical Skipper” and “Minimalist Explorer”!
