I have an one app that depends on another app. I have a table in the first app that receives a value when the support app starts and stops by user interaction. However, what I need is a way to tell if the support app stops responding and not actually shut down. In my first app table I have a datetime() field to recieve pings from the support app. I need a way to monitor the dtaetime field and tell if it stops incrementing and give me a prompt and then cause the prompt to dissappear when the support app resumes.
