Kids Picture Viewer with Child Lock is the best parental control app for Android phones. Parents can use this app to protect their photos and videos from their children. With this app, you can control what your kids see on their phone, including social media, photos, videos, and games.

Parents can select the list of photos and videos that kids can view. If you want to see the images on your phone, you can choose the mobile device you use most often. For example, if you use your phone more than once a day, you can select the photos and videos you want to view on your phone.

Parents can also record the sound for each image. This way, they will be able to listen to the recorded sound as they view the images in a slideshow.
