ProductionPro is available on two platforms:
An iPad App, which can be downloaded on the iPad Apple App Store
A Web App, which can be accessed via any internet connected device such as laptops (Mac or PC), phones (Android or iOS) or tablets (Chromebook, Surface, etc).
Both platforms have the same functionality, with slight differences in the UI. Depending on which platform you're using, you can find support articles for the web app here; if you're using the iPad app, you can find those support articles here.
