Boop the nose
When the sniffing starts, boop the nose. Sniffari keeps the clock, and every walk shows how much of it was sniffing.
Sniffari
Walks measured by what your dog cares about.
Sniffari times how long your dog spends sniffing, counts pee and poop breaks, and maps the route — so a walk is judged by what it did for the dog, not by your pace.
In a 2019 study, dogs allowed to search with their noses became measurably more optimistic. Duranton & Horowitz, 2019
A walk, from the dog's side
Pee & poop, one tap each
Counts on the walk screen, pins on the map, and a minus button for the accidental tap.
Daily totals across walks
Two short walks and one long one add up on Home, so the day tells the truth even when no single walk does.
A typical walk, per dog
After a few walks, each dog gets a baseline. A summary can say “about 2 minutes more sniffing than usual.” Never a goal.
Favorite sniff spots
A map of where your dog sniffs most, sized by how long they linger. Analysis about the dog, not about you.

Every walk gets a summary. Every dog gets a profile.
Why sniffing matters
Sniffari times the sniffing because the research says it's the part of the walk that does the most for the dog. Here's what that research actually shows.
Smell is most of how a dog reads the world
Dogs have on the order of 100 to 300 million scent receptors, against roughly 5 million in people, and can sniff many times a second. A sniff stop that looks like nothing to us is a dog reading the news.

Sniffing lowers a dog's pulse
A French field study measured dogs' pulse during walks. The more intensely a dog sniffed, the lower its pulse dropped. Sniffing isn't just information for a dog; it's how a dog calms down.

Sniffing makes dogs more optimistic
Researchers split 20 pet dogs into two groups for two weeks. One group played sniffing games, hunting for hidden treats with their noses. The other did the same amount of walking and got the same treats, but had to walk at heel with no sniffing. Afterwards, the sniffing dogs were more hopeful: shown a bowl that might or might not have food in it, they went to check it out sooner. The dogs that hadn't been allowed to sniff hung back. Same exercise, same rewards — the only difference was the sniffing.

What we don't claim: that sniffing extends life, treats anxiety, or that there is a right number of minutes. The app shows how much of each walk was sniffing and never sets a goal.
