Need a small program Written for Android

I have in excess of 200 Windows PC's/Servers running backups each night. Some backup to the cloud and some to a local NAS unit. Each backup sends an email to a Gmail account informing me if the backup has been successful or failed. If I do not get a an email at all I assume the backup has failed.

I need a program which when opened, will check my Inbox going back to 17:00 the previous day and will detail which backups have worked and which have not. This will be based on specific text with in the body of the email.

The program would allow the user to add and remove companies. The user would also be able to input/change which words/text in the email the program checks for to confirm a backup success or failure. I expect the program will be in Java as it will run on an Android.
