I like how easy it is to use (and get used to) since it's pretty much like other programs. When you have more options, it may be less intuitive to navigate. It's not as robust or complete as something like Audacity. But it does do the job! So far so good. I don't think I've had any issues with this program. It will play all of my music in any format including wav and mp3. You can even edit waveform images if that's your thing. The best part about this app was that it allowed us to edit our own music in an easy way without having any prior knowledge of how things work or where we would have had access if there were more complicated programs available at times like "WAVOSAUR". If you want something simple yet effective then go with WaveOusaurus! It's great because I can use my phone as both camera/recorder AND recorder when needed (which saves me money by not buying two separate devices).
