Use it in the field, classroom, truck, blind, trailhead, backyard, or anywhere curiosity kicks in. Browse species pages, photos, maps, habitat notes, seasonal patterns, conservation context, and taxonomy — without needing an account or subscription.
Built for Montana’s natural world — from alpine ridges and prairie breaks to wetlands, forests, riparian corridors, and backyard discoveries.

Built like a field instrument, not a feed.
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.
We don't track you
No analytics SDKs, no marketing pixels, no behavioral profiling. Apps work offline. Your records are yours.
Open in spirit
We contribute back to iNaturalist, eBird, and OSM. We respect API terms. We publish our data limitations alongside our successes.
We've thought about how you actually work.
