OmniDex

Field Guides

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, from wildlife, birds and sharks to dinosaurs and space.

Seven Dexes are available now. WildDex and AstroDex are free; the others are one-time in-app purchases.

WildDexAnimals of land, sea and air Free

AstroDexPlanets, stars and spacecraft Free

BirdDexBirds of the world In-app

PaleoDexDinosaurs and extinct animals In-app

Seven field guides

Free: WildDex (animals of land, sea and air) and AstroDex (planets, stars and spacecraft)
In-app purchases: BirdDex (birds of the world), SharkDex (sharks, rays and their relatives), ReptileDex (reptiles and amphibians), OceanDex (life in the sea) and PaleoDex (dinosaurs and extinct animals)
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.

Laid out like a field card

Identity

Every entry starts with its name, scientific name and classification.

Attributes

Habitat, range, diet, size, conservation status and more, depending on the Dex.

Field notes

Notes and facts for each entry, with related entries to read next.

Honest figures

Figures that are estimates or disputed are labelled that way.

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.
