Delay Effects is a free guitar amplifier simulator app developed by Githara Studios Pty Ltd. It is available for Android devices and falls under the category of Multimedia with a subcategory of Music & Radio. The app is designed to create a delay effect, which ranges from 1/4 second to 1 second depending on the device. The app has a unique approach of accepting the delay and providing an option to increase it so that users can play in harmony with themselves.

The app allows users to plug in an electric guitar if they have the right cable, or use an acoustic guitar with a microphone and headphones. However, it is important to note that using the app without the right cable or headphones may result in feedback due to the proximity of the microphone and the speaker on mobile devices. The app also provides a few basic effects for users to experiment with and enjoy.
