I built a free Android app for tracking EPA Level IV ecoregions in the field

Birders have life lists. Alpinists track peaks. I wanted something similar for ecological patterns across landscapes, so I built Ecoseek.
Ecoseek is an Android app centered on EPA Level IV ecoregions—smaller ecological units that often capture meaningful variation in geology, vegetation, hydrology, land use, and climate better than broad state or biome labels. The idea is simple: instead of just logging that you “went hiking,” you log which ecoregion you were actually in.
A few things it does:
• lets you explore ecoregion boundaries on a map
• shows descriptions for individual ecoregions
• helps surface protected areas to visit
• lets you log field outings with notes/photos
• tracks which ecoregions you’ve already explored in a given state
• pulls in discovery content using recent iNaturalist observation patterns
What I like most about the concept is that it nudges outdoor recreation toward ecological literacy. Two places can look superficially similar but function very differently ecologically, and ecoregions are a useful framework for noticing that.
It’s also built to work offline and keeps data local to the device, which felt important for field use.
If you’re into biogeography, landscape ecology, field naturalism, or just want a more ecology-focused way to explore, I’d genuinely love feedback from this community.
