Keeps bugging with ad on startup; sound mixing capability is good

It is really annoying that the app keeps showing an ad on startup, nagging me to buy a new sound, just when I want to concentrate. I’d like it much better if they kept the market in the menu and not showed the popup, so that I can buy one if I want one. For now I’m angry about the market so I feel like I would deliberately avoid buying any sound even if I wanted one.
