12+ datasets
Authoritative sources, named
Every claim our apps make is sourced. We tell you where the data came from, when it was last updated, and what it doesn't cover.
Local-first
We don't track you
No analytics SDKs, no marketing pixels, no behavioral profiling. Apps work offline. Your records are yours.
Citizen-science
Open in spirit
We contribute back to iNaturalist, eBird, and OSM. We respect API terms. We publish our data limitations alongside our successes.
For your work
We've thought about how you actually work.
