In order to use the SongRiffer app, you will need to sign up for an account. This is needed to synchronize your data so you can access them from all your devices (computer and smartphone).
If you wish to have access to the mobile app, please contact us at email@example.com and we'll see what we can do!
Our goal is to have the best experience with all file types and integrate them as well as we can. Regarding DAW files, we won't be able to preview them in the app, and they don't make much sense on the mobile app. For now they are not supported.
If you have any question not covered here, please contact us at firstname.lastname@example.org and we'll answer you as soon as possible.
