PetVoila! helps pet owners find and report lost pets.
If you lose your pet, you can post an alert which​ is broadcast to all the users around you. When someone finds your pet, they can then use the app to contact you privately.
If you find a stray pet, you can use the app to report it. The owner can then contact you privately using the app to pick it up.
The app also shows you lost and found pets up to 25 miles away.
