This app is average compared to most apps used for ringtones and ringtone construction. It is fine for basic ringtone construction. Like most apps of this type it still requires you to upload any ringtone you have created to your computer and transfer it to your phone by iTunes. Many people find this annoying but this need for step-by-step transfer is typical for this type of app.
What I find annoying is that it is DRM controlled media such as songs cannot be imported. Again this prohibition is common for many apps of this type. Furthermore you cannot edit ringtones down to text tones or alert messages or shorten messages to make them more appropriate for text msg and such.
Many other reviews complain that it will send you monthly notifications or weekly notifications about the status of your ringtones or other advertisements. However I have found you can turn off notifications on the iPhone for this app and thus eliminating these annoyances.
If you understand many of these limitations and are willing to work through these extra steps, then this app is slightly above other apps that create ringtones.
