Record butterfly counts offline in the field, sync when you're back, and explore diversity indices, phenology curves, and your personal life list — all in one app.
What's included
Log counts in the field with no signal. Surveys sync automatically when you reconnect.
Record species, count, and location for each survey. Observations attach to GPS-tagged counts.
Every species you've ever recorded, searchable and sortable by first sighting, frequency, or family.
Shannon diversity, Simpson index, Pielou evenness, and encounter-rate trends — computed from your own data.
All your GPS-tagged surveys on a personal field map. Pin size reflects species richness per survey.
Pending drafts sync in the background when connectivity returns — no manual uploads needed.
