I have the 90 day app. It sets a reminder in your phone calendar giving the appropriate date range you must make your 90 day report. Nothing more. You still have to do the report either in person, by mail or by internet. I like it.
I've downloaded a 90 day app on my android phone. It makes an entry on my phone calendar showing the earliest and latest I can do the report. The calendar can therefore give me reminders. I think its very useful and its FREE!
