Unpolished and buggy
The app has potential to become something useful and fun to play with or produce loops with, but right now its quite buggy and extremely unpolished. Samples selected dont get saved properly, so going back to edit patterns later is a hit or miss proposition: your only true option is to create something in one sitting and export it immediately. In addition, the samples included are taken from the Freesound project, which only grants a limited license for their use, and requires attribution: this is not something that is spelled out in the app documentation.
