Well to basically put this into words: "This app is awesome!" Before I found this app, I would use audacity to make my ringtones and now I can just do it on my phone and save them directly to ringtone, notification, or alarms. It even allows me to edit ringtones that have been downloaded from apps like zedge. The file sizes comparatively to audacity are slightly smaller which is a definite good thing. Pros: Easy to use simple user interface saves as universal format mp3 ability to zoom in on the waveform (big plus) can record a track and edit it right there Cons: No ability to turn stereo sound into mono ability to save as other formats is non existent Conclusion: In all this is a must have app for any android user. never pay for ringtones again but then again i don't know anyone that really does anymore. I have never had an issue with force closing and the app is snappy and responds fast. Just download it and start making some ringtone.
