## What is Benthoscore?

Count the bugs, score the stream. Benthoscore takes benthic macroinvertebrate surveys from field tally to biotic index without a signal bar in sight.

Keep multiple surveys organized with site, date, collectors, reach, mesh, coordinates, season, and method context. Start with named EPA RBP 200-organism or EPA NRSA 500-organism profiles, or document a local custom method.

KEY FEATURES
- Multi-survey library with duplicate, archive, restore, and delete workflows
- Protocol-aware target progress and record-quality checks
- Searchable reference with 24 taxon profiles with identification cues and ecological traits
- EPT, HBI, diversity, dominance, clinger, intolerant, and feeding-group results
- Eight habitat attributes and contextual water observations
- Multi-page PDF field report, analysis-ready CSV, and structured JSON evidence
- Official EPA and USGS method sources in the Methods reference and report
- Atomic on-device persistence, recovery backup, preserved unreadable files, and legacy migration
- No account, ads, analytics, tracking, subscription, or network requirement

Benthoscore does not diagnose water quality or assign a regulatory condition class. Collection, subsampling, taxonomy, tolerance, and interpretation rules vary; apply the responsible agency method before making a management decision.
