Paint Tester Pro is a useful app for iPhone users who are considering painting their walls but are not sure which color to choose. With this app, you can test different paint colors on pictures of your own home, so you can see how they would look before you start painting.

The app offers a variety of tools that make it easy to change the wall color in a picture in a matter of seconds. You can start by taking a picture of the room you want to paint and use the paint bucket to apply colors to the walls. In a well-lit photo, the smart paint bucket will color the wall without bleeding onto neighboring walls or the ceiling. You can even use multiple colors at the same time to try an accent wall!
