OmniDex: Field Guides
Wildlife, dinosaurs and space
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Multiple field guides in one app. Scan an animal with your camera to find it in WildDex, BirdDex and more.
OmniDex is a library of field guides in one app. Each guide, called a Dex, covers one subject with its own look and its own details.
Buy a Dex on its own, or buy Everything to unlock every paid Dex, including ones added later. Each is a one-time purchase. Before you buy, a locked Dex shows what it covers and a few of its entries. Restore Purchases is in Settings. More Dexes will be coming soon.
LAID OUT LIKE A FIELD CARD
• Every entry has its name, scientific name and classification at the top
• Attributes at a glance: habitat, range, diet, size, conservation status and more, depending on the Dex
• Field notes and facts for each entry, with related entries to read next
• Figures that are estimates or disputed are labelled that way, so you know how solid they are
FIND WHAT YOU'RE LOOKING FOR
• Browse a Dex entry by entry, or step through with previous and next
• Search a Dex as you type, or search every Dex at once from the library
• Jump back to the Dexes you opened recently
SCAN WHAT YOU SEE
• Point your camera at an animal, or choose a photo from your library, and OmniDex suggests what it is and how sure it is
• Scan in WildDex, BirdDex, SharkDex or ReptileDex, or scan from the library to check all four at once
• A match opens its entry. If it's in a Dex you haven't bought, OmniDex shows which Dex has it
• Entries you find with the camera are marked as discovered, and each of those Dexes counts how many you've found
• Scans are counted per day; the scan screen shows how many you have left
• Your photo is sent to OmniDex's server to be identified. If you allow location, it includes where it was taken. Location is optional
RESEARCH WHAT'S MISSING
• Search WildDex, AstroDex, BirdDex, SharkDex, ReptileDex or PaleoDex for something it doesn't have yet, and OmniDex can research it and add what it finds as a new entry
• A scan match that no Dex has an entry for can be researched the same way
• Researched entries are marked as researched and unverified, and listed in their Dex under Researched entries
• Each subject is researched once and shared: anyone who researches it later gets the same entry
• New research is counted per day; OmniDex shows how many you have left
• What you search for is sent to OmniDex's server to research it
MAKE IT YOURS
• Star the entries you love and filter a Dex to just your favourites
• See which entries you've opened; new ones are tagged NEW
• Your recently opened entries and favourites are saved on your device, so they're there when you lose your connection
• Share an entry as a picture card
MADE FOR iPHONE DUO
Unfold iPhone Duo and an entry spreads across both halves: the specimen and its identity on one side, field notes and attributes on the other. Nothing important sits under the hinge. Folded, it's a single column on the outer display. OmniDex also works on iPhone and iPad.
OmniDex needs an internet connection to load Dexes and Sign in with Apple to get started.
