Good app, but…
On the iPad version, there is no way to save a .helio file, despite the fact that it creates a 0kb .helio file on song creation. While customizing instruments in the orchestra pit, a lot of times when I try to add some effects, the app immediately crashes. On the page where you create projects, it has a list of projects recently worked on, but when you click on those projects, it disappears from the list, and adds an empty item to the studio menu and deletes the project with no undo.
