Annotation Control
Read full descriptionHide full description
The Annotation Control app allows you to annotate from your iPad or iPhone. This app may only be used with the Williams AV Annotation Pro Plus annotation system. The Apple device being used must be on the same Wi-Fi network as the Annotation Pro system. Open the app and select the Connect icon. Find your Annotation Pro system in the list of available systems and select it. Once connected, draw with your fingers to make any desired annotations. If the app is moved to the background (when checking notifications or using other apps), the connection to the Annotation Pro system will be lost. When the app is resumed from the background, the app will attempt to reconnect with permission. If the app takes too long to reconnect or is unable to connect, try to connect by pressing the Available Connections button.

Verdict
The clearest difference is in-app purchases: Annotation Control at none against Spreach's 1. Annotation Control also leads on iOS requirement (11.0 vs 18.6). On price, ads and device support there is nothing between them.
