ShowCast is a utility and tools app for Android 9.0 developed by LifeBoat Software. It allows users to present pictures to ChromeCast from their phone or tablet. With ShowCast, users can pan and zoom on their phone, and the picture shown on their ChromeCast will do the same. The app also prevents the picture from rotating, locking the picture on the device from rotating the picture on the ChromeCast.

Moreover, ShowCast provides users with the ability to do a phone presentation or a tablet presentation using only their phone and a ChromeCast or their tablet and a ChromeCast. The app is simple to use; just connect the phone to a ChromeCast, point to the first slide of the presentation on the phone, and press start. ShowCast supports selectable orientation of the slides (portrait or landscape), rotation lock during the presentation, and pinch-zoom on slides during the presentation.

In addition, ShowCast has added features such as the ability to display notes on the phone during the presentation, and full ChromeCast support. Users do not need the ChromeCast app to mirror their phone; they can just start the presentation and select their ChromeCast device using the usual ChromeCast button. With ShowCast, users only need to bring their phone and a ChromeCast for their next presentation.
