For fun, not science: the score compares colors, light and texture in the two photos, on your device. Photos are never stored, uploaded, or used for training.
Make it a weekly twin check
Pick your Twin Day. Each week on that day, grab a fresh photo pair, run the match, and try to beat your twin score.
Stored only in this browser, and only if you turn it on. Nothing is emailed and no account is created — PupTwin never sees your choice.
How it works
Three steps. Ten seconds. That's the whole thing.
-
Upload two photos
Your photo and your dog's. Face the camera, good lighting, no sunglasses on either of you.
-
Get your twin score
Your verdict card appears instantly — your score, side by side, ready to go.
-
Share it everywhere
Share it, duet it, tag your twin. Your card is built for Stories, Reels, and TikTok.
Private by design
Your photos never leave your phone.
The plain-English version: your pictures are scored on your device — never stored, never used to train anything.
Made to share
Every result exports as a Story-ready card with your score — 1080×1920, built for the feed.
Questions, answered
Everything people ask before meeting their twin.
What is a twin score?
It's a fun score — 1 to 100 — of how much you and your dog look alike. Snap two photos, get your number and a shareable twin card.
Is PupTwin free?
Yes — free while we're in beta. Join the waitlist and you'll hear the second we launch.
Do you keep my photos?
No. Your photos are scored on your own phone. They're never stored, never uploaded, and never used to train anything.
What photo works best?
Face the camera, good lighting, no sunglasses — on either of you. Clear, front-facing photos get the best reads.
How do I share my card?
Every result exports as a Story-ready card (1080×1920) built for TikTok, Reels, and Stories. Sharing gives your twin a gold star.
