Use Seek when you want an instant name with no account and nothing shared. Use iNaturalist when you want real people to confirm the identification and you don’t mind posting the sighting publicly. Both are free and both come from the same nonprofit, so this isn’t a question of which one is better made. It’s a question of whether you want speed and privacy or confirmation.
The short version: Seek answers in the viewfinder and keeps to itself. iNaturalist answers with a suggestion, then a community either agrees or corrects it.
iNaturalist vs Seek at a glance #
| Seek by iNaturalist | iNaturalist | |
|---|---|---|
| Price | Free | Free |
| Account | Not required | Required to post observations |
| How you get an ID | Point the camera, it recognizes what it can | Upload a photo, get ranked suggestions, community reviews |
| Human confirmation | No | Yes, that’s the point |
| Speed | Seconds | Suggestion in seconds, confirmation in hours to weeks |
| Your sighting is | Kept on your phone unless you share it | Posted publicly with date and location |
| Age rating | 4+ | Sign-in is for ages 13 and up |
| Species recognized | Around 80,000 after a recent update, up from about 20,000 | Anything the community can identify |
Both apps are published by iNaturalist and lean on the same pile of community-verified photos, so the computer’s first guess is often similar. What differs is what happens after that guess.
How Seek works #
Seek is the point-and-shoot one. You open the camera, aim it at an insect, plant or mushroom, and the app tries to name it live. There’s no upload step and no waiting for anyone.
Two things make it unusual. First, its App Store listing states plainly that Seek “does not require registration and does not collect any user data by default.” You can use it without making an account at all. Second, it’s built for kids: a 4+ age rating, badges for observing new groups of species, and rotating monthly challenges. Signing in with an iNaturalist account is optional and meant for ages 13 and up.
The catch is that Seek would rather be vague than wrong. When it can’t separate the species, it stops at a broader group, such as the genus or the family, and tells you that’s as far as it got. For a nature walk that’s fine. For “what is biting me in my bedroom,” being told your bug is a beetle of some kind isn’t an answer.
Seek’s listing also doesn’t say whether recognition keeps working with no signal, so don’t plan a backcountry trip around it.
How iNaturalist works #
iNaturalist is a record-keeping platform that happens to have an ID model attached. You upload a photo, the computer vision offers ranked suggestions by comparing your photo against species recorded in your region, you pick one or leave it broad, and you post it as an observation with a date and location.
Then people show up. Other users, including specialists who follow particular groups, add their own identifications. When enough of them agree, the observation reaches Research Grade and becomes usable by researchers. That human layer is the reason iNaturalist is the most trustworthy option for anything hard, like small brown beetles, jumping spiders or wasps.
Two practical notes. The original app is now called iNaturalist Classic, and iNaturalist recommends the newer redesigned app instead; both are free. And the Classic app’s listing says species identification requires online access, so it isn’t an offline tool either.
The trade is your privacy. An observation is public, and iNaturalist’s privacy label lists precise location linked to your identity. You can obscure the coordinates of a sighting, which matters if the bug is in your bedroom rather than in a park.
Which one should you use? #
- A mystery bug in your house, and you want to know if it bites: neither is ideal alone. Get a name fast, then confirm with a person if the answer changes what you do. See what is this bug in my house.
- Walking with kids: Seek, easily. Badges and challenges are the whole appeal, and there’s no sign-up.
- You want to be right: iNaturalist. Nothing beats an expert looking at your photo.
- You’re documenting what lives on your property: iNaturalist, since your observations accumulate into a record.
- You don’t want a sighting posted publicly: Seek, or an app that never sends the photo anywhere.
Where Insect Identity fits #
Our app, Insect Identity, sits in the gap both of these leave: a fast, private answer when you have no signal and no interest in joining a community. You photograph the bug or pick one from your gallery, and a model that ships inside the app returns a best match with a confidence score plus four runners-up, in about a second, with the photo never leaving the phone. It works in airplane mode, in a basement or on a trail, and there’s no account.
Its limits are worth stating next to the two above. It knows 224 species, chosen from the insects, spiders and ticks people commonly run into in North America and Europe, so a rare or tropical find will come back as its nearest common lookalike with a low score. It gives you names and numbers, not species write-ups, distribution maps, badges or community confirmation. For anything where being wrong costs money or health, the answer still belongs in front of a person.
Plenty of people run two apps: something quick for the name, then iNaturalist or a diagnostic lab when the answer matters. Our comparison of insect identification apps covers the rest of the field, including Google Lens and the paid ones.
Does the photo matter more than the app? #
Usually, yes. All three apps shrink your image before analyzing it, so a bug occupying a tenth of the frame leaves the model a patch a few dozen pixels wide, with the antennae and wing pattern gone. Fill the frame, get a top view and a side view, use soft light and crop tight before submitting. The full method is in how to photograph a bug for identification, and how accurate insect identification apps are explains why two apps can disagree on the same photo.
Frequently asked questions #
Is Seek the same as iNaturalist? #
They’re different apps from the same organization. Seek is the camera-first, no-account version aimed at families and casual use. iNaturalist is the full platform where you post observations and other people identify them. Seek can link to an iNaturalist account, but doesn’t need one.
Is iNaturalist free? #
Yes. iNaturalist is a nonprofit and both its apps are free to download and use. You need an account to post observations and take part in identifications.
Which is more accurate, Seek or iNaturalist? #
For a final answer, iNaturalist, because people review the computer’s suggestion. Seek’s instant guess comes from the same kind of model, but nobody checks it, and Seek often deliberately stops at a broader group rather than naming a species it isn’t sure about.
Can kids use iNaturalist? #
Signing in to iNaturalist is intended for ages 13 and up. Seek is rated 4+ and needs no sign-in, which is why it’s the one usually recommended for younger children and classrooms.
Do these apps work without internet? #
iNaturalist Classic’s listing says identification requires online access. Seek’s listing doesn’t state offline support either way. If you need identification with no signal, use an app that runs its model on the phone and says so.
