Seek
Seek identifies plants, animals, fungi, and other living things in real time by pointing the camera at them.
Turn any walk outdoors into an instant nature discovery session.
Seek is a free nature identification app developed by iNaturalist, a nonprofit organization supported by the California Academy of Sciences and the National Geographic Society. It uses image recognition technology trained on millions of community-submitted wildlife observations to identify plants, animals, fungi, insects, amphibians, and more — all in real time through the phone's camera.
The app is designed to work without a user account or registration, making it completely anonymous by default and safe for children. Location data is used only in a generalized, obscured form to suggest species commonly found in the area, and no precise location is ever stored.
Seek suits anyone who spends time outdoors and wants quick, on-the-spot answers about the natural world — from families on a weekend walk to hikers, gardeners, students, and curious individuals. It combines a clean, intuitive interface with a badge and challenge system that rewards ongoing exploration, giving the experience a light, game-like quality without becoming distracting.
Apps are frequently updated and may change over time. While we aim to keep our reviews accurate and up to date, some information may become outdated or no longer reflect the current version.

How to Use
Using Seek requires no setup. The app opens directly to its camera, called the Seek Camera, which starts scanning the environment immediately. Point the camera at any living thing — a flower, a bird, a mushroom, a beetle — and the app begins analysing the image in real time. Within seconds, it offers an identification, starting from a broad category and narrowing down to genus or species level as the image becomes clearer and more data is available.
Once a species is identified, the app displays a species profile with information about the organism — its taxonomy, a brief description, and where it typically lives. Users can save the observation to their personal log, which builds up over time into a record of everything they have found.
The badge system tracks progress across categories such as plants, birds, insects, fungi, and mammals. Completing observations earns badges, and seasonal challenges give users specific targets to aim for. Location services are used in an obscured form to filter species suggestions to those likely found in the user's general area, improving the relevance of identifications without compromising privacy.
Users who already have an iNaturalist account can optionally link it, enabling them to upload observations to the wider citizen science community. This step is entirely optional and not needed for the core identification experience.
Strongest Points:
✓ Completely free with no paywalls, subscriptions, or hidden costs
✓ No account or registration required — works out of the box for anyone, including children
✓ Real-time identification directly through the live camera view, no waiting or uploading
✓ Covers a wide range of organisms — plants, insects, birds, amphibians, fungi, and more
✓ Strong privacy design with obscured location data and no personal data collected by default
Weaker Points:
✕ Identification accuracy can be inconsistent, particularly for species that look similar or in poor lighting
✕ Works best in regions with active iNaturalist communities — results may be weaker in less-documented areas
✕ Camera cannot zoom, making it harder to identify distant or small subjects
✕ Seek observations do not automatically sync with iNaturalist, so progress is not carried over
✕ Some users report occasional app freezes or crashes, particularly when saving observations

Applications and Features
Seek's core capability is its live camera identification engine, which draws on a vast database of iNaturalist observations to recognize thousands of species in real time. The recognition works across the full tree of life, covering flowering plants, mosses, fungi, insects, spiders, birds, reptiles, amphibians, fish, and mammals. Identifications are returned as a taxonomy path, narrowing from kingdom down to species level as the image becomes clearer.
Each confirmed species unlocks a species profile within the app, providing basic biological information and ecological context. Users build a personal observation log over time, which serves as a record of every species they have successfully identified. This log feeds directly into the badge system, which rewards milestones across categories such as plants, birds, insects, and fungi.
Seek also runs seasonal and themed challenges, giving users targeted goals to work toward during specific periods. Location-aware filtering uses an obscured, generalized version of the user's location to surface species that are commonly recorded in the area, making identifications more relevant without storing or sharing any precise location data.
The app supports optional iNaturalist account integration, allowing experienced users to contribute observations to the global citizen science database. For those who prefer to stay completely private, the app functions fully without any login at all.

App Summary
Seek is a solid, no-nonsense nature identification tool that delivers genuine value at no cost. Built and maintained by the nonprofit iNaturalist team, it stands apart from the many nature apps that push users toward paid plans — there are no paywalls here, no accounts required, and no personal data collected unless opted into.
It works best for families, hikers, educators, and curious outdoor enthusiasts who want quick, reliable answers about the plants and animals around them. The real-time identification, species profiles, and badge system combine into an experience that is genuinely useful and quietly motivating. The gamified elements are understated enough to feel purposeful rather than gimmicky.
The key limitations to keep in mind are identification accuracy in low-light or cluttered visual conditions, the inability to zoom within the in-app camera, and the lack of automatic sync with iNaturalist for those who also use the broader platform. These are real limitations, but they do not undermine the core experience for most casual users.

Questions & Answers: ⮛ (click to open)
Does Seek work without creating an account?
Yes — Seek requires no registration at all. The app opens directly to the camera and all core features, including identification, species profiles, observations, and badges, are fully available without signing in. An optional iNaturalist account can be linked for those who want to contribute to the citizen science community.
How accurate is Seek at identifying species?
Seek performs well with clear, well-lit images of common species, particularly in regions where the iNaturalist community is active. Accuracy drops in low light, with visually similar species, or in areas that are less well-documented. The app often identifies to genus level rather than exact species when confidence is lower.
Is Seek safe for children to use?
Seek is designed specifically with child safety in mind. It collects no personal data by default, requires no account for children under 13, and uses only an obscured version of the device's location. The content is age-appropriate and has an "Everyone" rating on both the App Store and Google Play.
Can Seek identify species offline?
Seek can perform basic identification without an active internet connection, since part of the recognition model runs locally on the device. However, a connection improves accuracy and enables location-based species filtering. For best results in areas with patchy signal, downloading recent observations in advance — when connected — is recommended.
Good to Knows: ⮛ (click to open)
• Seek was built with support from the California Academy of Sciences, National Geographic Society, WWF, and Netflix's Our Planet team.
• The app works without an internet connection for basic identification, though a connection improves species suggestions and location-based filtering.
• Children under 13 can use Seek without any account; parental permission is required only if they choose to link an iNaturalist profile.
Takeaways: ⮛ (click to open)
• Seek is one of the few genuinely free, no-account-required tools in its category — its nonprofit backing makes it a rare exception in a space crowded with freemium apps.
• Accuracy and regional coverage depend heavily on how well a given area is represented in the iNaturalist database, so results vary depending on where in the world the app is used.
• For families and casual nature explorers, Seek delivers a clean, low-pressure experience that genuinely encourages spending more time outdoors.
