Two Tulsans have built a top-selling iPhone app.
The app is called "Wood Camera," and it's a vintage photo editor.
It is number one in the App Store for paid apps.
Zach Garrett is one of the creators. He studied at ORU and is still living in Tulsa.
John Barnett is the other creator. He lived in Tulsa for about 10 years.
The app even beat out Minecraft and Star Wars Angry Birds.
