FishTally

Fast, offline fish sampling data collection for aquaculture research. Record, photograph, and export your data in the field.

FishTally is a purpose-built field tool for recording aquaculture sampling data.

Built for speed on the water: open a session, enter fish measurements, snap a photo, and move on. No internet required, no accounts, no distractions.

FEATURES • Create sampling sessions by tank/enclosure — or organize them under projects • Record fish ID/#, length, weight, and notes for each fish • Build your own custom data fields (numeric, text, dropdown, and multi-select) to track anything you need • Photograph each fish (multiple photos supported) with a built-in cropping tool and automatic metadata overlay burned into the image • Flag fish to exclude from statistics (mortalities, outliers, and more) with a recorded reason • See instant statistics — average length and weight, Fulton's condition factor, and charts • Edit any record inline, including custom fields, without leaving the entry screen • Export sessions as ZIP archives containing your data (CSV) and all photos and share via AirDrop, Mail, or save to Files • Metric and imperial units • All data stored locally on your device — no cloud, no sync
