Colorize Images is a free Android app that uses advanced machine learning algorithms to add vibrant colors to your black and white photos, giving them a fresh and modern look. The app is developed by Colorize Images and is available in the Multimedia category under Photography subcategory.

The app's interface is intuitive and easy to use. To colorize your photos, simply select an image from your device's gallery or share it from another app, and let the app do the rest. You can choose the colorization mode from a variety of options, including pre-defined palettes or custom colors like skin tones, hair colors, etc. The colorized images can be saved to your gallery or shared on social media.

The app is free to use, but you can unlock unlimited colorizations and remove ads by subscribing. The app uses GPU servers to ensure fast, high-quality colorizations without sacrificing your device's performance. The app is based on the DeOldify project and is recommended to use high-quality images with good contrast and sharpness for best results. However, the resulting colors may not be historically accurate or necessarily correct due to the lack of original color clues in black and white images.
