The first release applications are Point Of Sale and [Self Checkout](/feature-references/feature-references/self-checkout.md) applications that can be run at both Home and Flip positions. {% endhint %} ### Hardware Requirements * Commander Site Controller with C18 ### Software Requirements * Commander Site Controller base version 53.25.01 and higher ### Related topics * [Self Checkout](/feature-references/feature-references/self-checkout.md) — Configure and use the SCO application that App Selector can launch. * [Release 53 & Higher UI Reference](/feature-references/feature-references/release-53-and-higher-ui-reference.md) — Review C18 screen positions, orientations, and updated UI behavior. * [Auto Upgrade](/feature-references/feature-references/auto-upgrade.md) — See how default applications persist across upgrades. ### Using the App Selector #### Home Position The Point of Sale (POS) is the default application on home position when software is manually installed. After manual install, if application is changed to [Self Checkout (SCO)](/feature-references/feature-references/self-checkout.md), then SCO becomes the default application on home position and even after the next [auto upgrade (AU)](/feature-references/feature-references/auto-upgrade.md) SCO appears on home position as the default application. The latest selected application becomes the default application on that position and is retained across [AU](/feature-references/feature-references/auto-upgrade.md). ![](/files/d7330c1c6d544fc129549bf8128c9c99760773a9) **Countdown App Selector** If Point Of Sale application is default application on home position and if the screen is in flip position running Self Checkout, when you change the screen back to home position, you get the following screen: ![](/files/f32e75e15695c0fd2c1e25e8027fb4af42c13d17) {% hint style="info" %} The countdown starts from 60 seconds. If both home and flip positions are running the same application, this countdown app selector does not appear. {% endhint %} #### Flip Position The [Self Checkout (SCO)](/feature-references/feature-references/self-checkout.md) is the default application on flip position when software is manually installed. After manual install, if application is changed to Point Of Sale (POS), then POS becomes the default application on flip position and even after the next [auto upgrade (AU)](/feature-references/feature-references/auto-upgrade.md) POS appears on flip position as the default application. The latest selected application becomes the default application on that position and is retained across [AU](/feature-references/feature-references/auto-upgrade.md). ![](/files/4683b202d293c86084ff9fa9d19674a5ea197ad4) **Countdown App Selector** If Self Checkout application is the default application on flip position and if the screen is in home position where Point of Sale application is the default application, when you turn the screen to flip position, you get the following screen: ![](/files/2f107dfcee156ce326dfde9e5e7b54465a562b36) {% hint style="info" %} The countdown starts from 60 seconds.
