Loopa is a free audio looper application available on Android developed by leoleoleo. The app is designed to help guitarists and other musicians improve their skills by jamming with themselves. Loopa is a simple and easy-to-use app that has a big button to start and stop recording, looping, and pausing.

With Loopa, you can record up to 4 loops and adjust the loop delay to make your loop last shorter or longer. You can also delete the recording by pressing and holding the button for 2 seconds. To record more than one loop, make sure to use headphones to prevent the phone from recording itself.

Overall, Loopa is a great app for guitarists and other musicians to practice and improve their skills. It is a user-friendly and straightforward app that allows you to record, loop, and adjust your loops easily. The only downside is that it is only available on Android devices.
