Squirrel Sound is a free Android app developed by Nucharee Wankaew that aims to help people who are interested in squirrel extension and history, as well as those who simply enjoy the sound of squirrels. The app is designed to mimic the sounds of squirrels to help facilitate communication with other squirrels or attract them.

One of the main features of Squirrel Sound is its HD sound levels, which make the sounds of squirrels more realistic and lifelike. Additionally, the app does not require an internet connection, making it possible to use the app anywhere and anytime, even in areas without internet coverage. This is particularly useful for people who enjoy spending time in the forest, where internet access may be limited or non-existent.
