Just like on Motorola phones this app can repeat notification alert every some configurable time, to remind you that there is something waiting to be read. Currently it works on gmail messages, gtalk, sms and missed calls. You should enable it on the Accessibility menu, don't be scared by the popup Android shows you, this app has no authorization and can't do anything. This app is very simple and plain, few customizations, just the necessary to be sure to use less battery as possible. This is beta software. When stable it will cost just like an espresso. Comments are appreciated.
