dataretold turns live public datasets into focused single-purpose tools. Each page answers one specific question — "is anything dangerous heading our way?", "is now a good time to go for a run?" — using authoritative real-time sources rather than stale summaries.
All tools are free, work without an account, and refresh automatically.
Near-Earth Asteroid Tracker
Live close-approach data from NASA's Center for Near-Earth Object Studies. See which asteroids are passing close to Earth, how big they are, when they peak, and whether you can spot them from your location.
Go Outside Guide
Hourly air quality, UV index, and weather for any city in the world, combined into a clear "best window today" recommendation. Choose general, exercise, or sensitive-health mode for a tailored answer.
Photography Golden Hour
Golden hour, blue hour, sunrise, sunset, sun position, and moon phase for any city. Photographer-friendly with progressive depth for serious shoot planning. Free, no app required.
How dataretold works
Each tool follows the same pattern: a focused page that fetches and caches data from public APIs, then presents the parts that matter. Caching keeps pages fast, reduces load on the upstream services, and means a tool stays usable even during brief upstream hiccups.
Data sources are listed at the bottom of every tool page so you can verify the numbers yourself. Where a source disagrees with another well-known source, that's noted in the tool's "How this works" section rather than papered over.
