Map Generator, developed by Morning Forest Studio, is an Android app that is free to download from the Google Play Store. It is a unique app that uses the diamond-square algorithm to generate random height maps. The app allows users to set the roughness and smooth cycle numbers to create a custom map that they desire.

Apart from generating the map, the app offers the option to display the map in two formats: gray scale height map and colored image. Users can adjust the color by setting the water and mountain levels in the colored image. Both colored and gray images can be saved to the device.

Users can also view the generated terrain in 3D and rotate or zoom it as per their preference. However, the app does not provide any option to manually change heights or add water or other objects.

Overall, Map Generator is a fantastic tool for generating custom maps that can be used in various applications.
