The SFX Library+ app allows you to quickly play sound effects from a library of copyright-free audio directly on your device, or upload your own for easy access. This upgraded version of the SFX Library features no ads, is always available offline, and allows you to upload your own sound effects for seamless use. It's available for $1.99 USD in the app stores (may be different for some countries).

This is my first paid app and was developed after publishing the original SFX Library app. I wanted to add additional features without adding too many paywalls in the original app, so I created separate apps.
