crabhands: new musicfestivals is a free iPhone app developed by David Underwood. It falls under the multimedia category, specifically Music & Radio. The app allows users to track their favorite artists and receive notification alerts when new music is released on Spotify or when upcoming releases are discovered. Additionally, users can find out which festivals have the largest number of their artists in their lineup.

To get started, users simply need to connect their Spotify account to the app. From there, the app will scan for the artists that users follow and have saved music for. A list of the latest new releases will be available within the app, along with information about festival lineups and top festivals based on the number of artists playing.

The app provides daily notifications for new music releases and new top festivals. Users also have the option to add new releases to a playlist within their Spotify account. The app syncs with the user's Spotify artists before checking for new releases, and users can manually add artists to the app or make certain artists inactive if they don't want to receive notifications for them.

Please note that the app does not allow users to listen to releases within the app itself, but rather directs users to Spotify for that. It is also recommended to check the festival lineup before purchasing tickets, although the app does a good job of linking Spotify artists with Festicket artist listings.
