Dog vision and cat vision, live in your camera. See like a dog or a cat: your room, their toys and you. 30 animal vision lenses (29 animals plus a human reference), 8 of them free, and every lens tells you what is measured and what is stylized.

Animal Vision: Dog & Cat Eyes is an animal vision simulator. Use this animal vision camera to explore differences in color, detail, motion and focus as you switch lenses.

START WITH 8 FREE LENSES

Human, Dog, Cat, Horse, Snake, Deer, Rabbit and Mouse stay free for good, with no trial countdown. Pro is a one-time purchase, not a subscription.

DOG VISION: BLUE AND YELLOW, NOT BLACK AND WHITE

Wondering how dogs see, or how cats see? Try the Dog lens on a colorful toy or a familiar room to explore simulated differences in color and detail, and return to Human at any time to compare with the normal camera view.

CAT VISION: RED AND GREEN LOOK THE SAME

Switch to Cat for a different interpretation of color, shadows and peripheral softness. These camera filters are for exploration, not a test of your pet's eyesight.

CAN MY DOG SEE THIS TOY?

What colors do dogs see, and will your dog spot that toy on the lawn? On the Dog or Cat lens, tap Check a toy and point at it: the app compares its color with grass, floors, snow and your own background. Trainers get dummy and agility presets and a split view to show a client. On the Deer lens, see how deer see your gear, and how a turkey likely sees it; this checks color only, so always wear blaze orange. Flip to the front camera for a “How my cat sees me” card.

MORE ANIMALS, MORE TO DISCOVER

Explore Bird, Eagle, Owl, Fish, Shark, Octopus, Cuttlefish, Mantis Shrimp, Bee, Butterfly, Fly, Dragonfly, Spider, Chameleon, Cow, Frog, Cheetah, Reindeer, Sloth, Dragonfish, Mole and Hawkmoth with Pro or a rewarded preview. Discover compound-eye mosaics, focus effects and clearly labeled false-color simulations. Each lens includes its scientific basis, artistic enhancements, limitations and source references.

PRO AND REWARDED PREVIEWS

Pro unlocks all 30 lenses and future lenses, with no ads and no daily limits.

Each locked lens gives one free 5-second look a day. After that you can choose to watch a rewarded ad; completing it unlocks that lens for 60 seconds, up to 10 earned previews per device-local calendar day. Free users also see a full-screen ad about every fifth lens change, including changes between free lenses. There are no banner and no app-open ads.

Every day, three toy or trainer checks and one gear check are free; a rewarded ad adds more.

PHOTOS AND CLIPS

Tap the shutter for a photo, or hold it for a silent clip of up to 3 seconds (no microphone). A photo taken with Compare on can be saved or shared as before/after, 1:1 or 9:16. Open More, then Photo, to see a picture from your library through a lens; the app sees only the picture you pick. Nothing you save or share carries a watermark.

A SIMULATION, NOT A SENSOR

Animal vision cannot be reproduced exactly on a phone. These are educational approximations, not medical, behavioral or safety advice. Each lens shows an evidence badge, from Measured to Stylised, and “What's real here” explains what is science and what is embellished. The app is not a night-vision or thermal camera. Ultraviolet, polarization and heat effects are simulated from the visible camera image, not measured.

YOU CONTROL YOUR PHOTOS

Live frames are processed on your device and discarded. A photo or clip is saved only when you tap Save and leaves the app only when you choose Share or Save to Photos; the app records no audio and does not upload camera media. If Android backup is on, saved photos and clips may be included in your device backup. No account or sign-in is required. Lens effects and explanations work offline; ads, purchases, restores and external links need internet. Pro access may require online verification. Advertising and purchase services may process other data as described in the privacy policy.
