You just landed a fish, spotted an unfamiliar species in your tank, or pulled a catch from the dock — and you need to know what it is. FishLens reads the body, fins, and markings, names the species in seconds, and opens a field-guide profile covering habitat, edibility, and fishing tips, right at the water or the aquarium.
WHY ANGLERS AND AQUARISTS USE FISHLENS
Identify a fish in seconds.
Aim at the body, fins, or a clear side profile and FishLens names the species with a confidence indicator, then opens a field-guide profile: common and scientific names, family, freshwater or saltwater habitat, range, size, diet, and facts. From a dock panfish to a reef dweller in your tank, you finally know what you have.
Know what's catchable — and what to release.
Rules differ from water to water. Each identified fish gets a plain-language note on edibility awareness and handling, so you have context before keeping or releasing. When confidence is low, FishLens says so instead of guessing — and always points you back to your local fishing regulations.
Tips for the species in front of you.
Each profile adds practical context — typical habitat, season, bait and method notes for anglers, and basic water and tank-mate notes for aquarists — for real lakes, coasts, and home tanks.
Built for both worlds.
FishLens works the same on a riverbank, at a tide pool, or before an aquarium. One app covers freshwater, saltwater, and ornamental fish.
Keep a catch log that's all yours.
Save every fish you identify into a personal catch log on your device. Record the species, spot, date, and your notes; track the species and families you've found, and earn badges as you complete new families.
Learn as you go.
FishLens includes free in-app guides any fish lover can read: how confidence works, how to tell look-alikes apart, how to read fins and markings, and how to handle fish gently — for catch-and-release and tank fish.
HOW IT WORKS
1. Capture or pick a photo — frame the whole fish or a clear side profile in good light.
2. FishLens identifies the likely species and shows a confidence indicator; confirm or adjust by hand.
3. Open the field-guide profile for traits, habitat, edibility awareness, and tips.
4. Save it to your catch log and keep exploring.

A NOTE ON SAFETY AND REGULATIONS
FishLens is an educational identification tool, not a fishing-authority, medical, or food-safety service. Edibility notes are for general awareness only and can vary by location, season, size, water quality, and local contaminant advisories. Never rely on the app to decide whether a fish is safe to eat. Always follow your local fishing laws, size and bag limits, protected-species rules, and consumption advisories, and release protected or out-of-season fish. If illness from eating fish is suspected, contact a doctor or poison-control center immediately.
