All Blue - The Field Guide

Fish ID & Marine Field Guide

Free · Designed for iPad. Not verified for macOS.

Identify any fish. Track every catch. Explore the ocean by depth. A beautifully crafted field guide for anglers, divers, and the marine-curious. All Blue is a beautifully crafted field guide to marine species — built for anglers, divers, and anyone curious about life beneath the surface. Whether you're identifying a catch on the dock, planning your next dive, or just exploring the ocean from your couch, All Blue puts a complete, image-rich species database in your pocket. No accounts, no ads, no tracking. Just the fish. — A FIELD GUIDE WORTH CARRYING — Hundreds of marine species, each documented with: • High-resolution photographs from multiple angles • Scientific Latin names, family classification, and full taxonomy • Habitat layer, depth range, and geographic distribution • Adult and juvenile identification notes • Recommended fishing methods, baits, and lures Every entry is researched and curated — no AI-generated filler, no Wikipedia rewrites. — FIND ANY FISH IN SECONDS — A powerful multi-facet search lets you filter by: • Water type (saltwater, freshwater, brackish) • Habitat zone (reef, coastal, pelagic, benthic, deep) • Geographic region • Fishing method • Family or genus Mix and match to find exactly what you're looking for. Spotted something unfamiliar at a reef in the tropics? Two taps and you'll narrow it down. — YOUR PERSONAL LEDGER — Track your fishing journey: • Mark species as Caught when you land one • Mark species as Target for the ones still on your wishlist • Browse your personal collection grouped by status Your data lives only on your device — never uploaded, never shared. — DIVE IN — The signature Dive In mode arranges every species along a continuous depth axis — from sunlit reefs at 0 meters to the abyssal deep beyond 1,000 meters. Scroll down and watch the water darken, light shafts fade, and the ambient depth gauge climb as you descend through ocean layers. It's a meditation, an exploration, and a different way to understand who lives where. — PRIVACY FIRST — All Blue collects nothing. No accounts. No analytics. No advertising. No tracking SDKs. Your catches, targets, and browsing stay on your device. — DESIGNED WITH CARE — Hand-crafted with custom typography, precise spacing, and a minimal dark palette designed to fade away and let the species shine. Optimized for iPhone with native iOS gestures, haptic feedback, and a thoughtful field-guide aesthetic. The fish are the point. We just got out of the way.
