Approvl
Read full descriptionHide full description
Approvl is for music producers who want feedback and approval on songs and mixes from their artists, labels etc. Capturing written or verbal comments on the timeline allows the producer to fine tune the mix and ensure the client or label are happy with the end product. Doing this manually involves countless phone calls, emails and texts and Approvl makes this efficient and easy for both producer and artist. Mixes can be reviewed on Mac, iPad or iPhone also making it easy for mixes to approved on the road, in the van or wherever the artist is. Mixes can also be approved through a web link. Approvl is a paid monthly or annual subscription for producers but is free to approvers. Supplied according to standard Apple Terms of Use (EULA) found here: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
