It's an interesting idea, but this app missed some extremely important features, namely: a landscape mode, as well as a custom notification sound. Why? Those are extremely easy features to add! My use case is placing my phone on a stand in landscape mode so I can charge it while at work. I want a custom notification sound at work, and I want to be able to watch the timer go down without the screen stuck in portrait. Also, I keep the screen on, and the app disses me because I have the app open.
