About Dias

Dias is a free app to track, visualize, and share your travels. Create maps of where you've been — visits to national parks, continents, countries, states, and more, with dates and notes — and publish them privately, publicly, or collaboratively.

What you can do

• Create maps — One for every trip, place, or chapter; keep each one private, publish it, or invite others to add to it
• Track visits — Log national parks, state parks, campgrounds, and points of interest
• Save destinations — Bookmark locations you want to visit and track your travel goals
• Visualize travel — See your journeys on interactive maps with park boundaries
• Share profiles — Your public profile shows the maps you've published and your progress
• Discover destinations — Explore a comprehensive directory of parks across North America

Features

• Maps that are draft, private, public, or collaborative — each with its own URL
• Personal travel profiles with public URLs
• Visit logging with flexible date precision (day, month, or year)
• Routes between destinations (drive, walk, cycle, or fly) that credit every region crossed
• Want to go list for saving places you plan to visit
• Interactive maps with location boundaries
• Progress tracking (e.g., "42 of 63 National Parks visited")
• Global search with fuzzy matching (⌘K / Ctrl+K)

Origin story

Dias started as a personal travel record — a way to track visits to national parks and remember the details of each trip. It evolved into a platform for anyone who wants to document their outdoor adventures and see their progress over time.
