Tossco
Just developed for your fleet is the iScream app. Allows you to get your message across without wear and tear on the vocal chords while keeping a close eye on ice cream inventory in the forward galley.
Of wider appeal is the iICapt app. This is for F/O's and S/O's when confronted with the iToss app.
Still under development for the AOA is the iPushback app. This has been a long time in the gestation after some early setbacks to the prototype. Hopefully it will be available within the next ten years.
