Excellent app!
Definitely worth it if you need to actually hear your email notifications or are uses to a blackberry. The pop up is super helpful too. The shutting down automatically problem seems to have disappeared with a new update (although even before it was better than the stock notifications). If you are having it shut down you are probably running 15 apps in the background that you arent using. Just turn them off and all your apps will work better (google it if you dont know how. It is easy).
Also, support was amazing! Ridiculously fast reply.
Buy this app if you need to be properly notified of email and respond quickly.
