I have to be honest: this app looks poorly designed. I'm not commenting in terms of functionality, just the design. It looks like you drew it up in MS Paint. I know that is harsh, and I hope you'll take it as constructive criticism, not a cut against you personally.
Also, what is a dual charge alert? And does it really include millions of themes?!
EDIT: If the dual charge alert is the screenshot of one alert telling you when the main charge is done and another telling you when the trickle charge is done, I'm pretty sure Battery Doctor Pro does this as well.
