Hi, I'm Big Red
Every walk counts.
Now I can prove it.
Doggy Doo tracks our walks with your phone and turns them into my steps, my streak and a weekly health score. No collar, no tracker. Just you, me and the leash.

Doggy Doo is a free iPhone app, made in Austin, Texas, that tracks your dog’s walks with just your phone, with no collar or tracker, and turns them into breed-adjusted dog steps, streaks and a weekly health score.

FAQ
Questions from humans.
Do I need a collar or tracker?+
No. Doggy Doo uses your phone’s GPS, so all you need is your phone in your pocket while you walk.
How do you count my dog’s steps?+
From the distance you walk, adjusted for your dog’s size and age. Smaller legs take more steps, so the numbers fit your dog.
What is the weekly health score?+
A score out of 100 based on how many days you walked in the last week and how long, compared with a target for your dog’s size, age and energy.
Will it keep tracking if my screen locks?+
Yes. In the iPhone app, tracking keeps running in the background, so you can put your phone away and enjoy the walk.
Is there a Strava for dogs?+
Yes. Doggy Doo works like Strava for dogs: record a walk with your phone’s GPS, then post it to a community feed, follow other dog walkers, keep a streak going and climb a weekly leaderboard. It’s free on iPhone.
What’s the best dog walk tracker app without a collar?+
If you don’t want to buy a GPS collar, use an app that tracks with your phone. Doggy Doo is free, needs no collar or tracker, and turns each walk into breed-adjusted dog steps, a weekly health score and streaks. Other phone-based options include Tails, TrackMyPaw and Steps4Dogs; see our comparison of dog walk apps that work without a collar.
Is Doggy Doo free?+

Who makes Doggy Doo?+
