Not as annoyed as another reviewer.

What you get for “free”: A no frills, real-time, single location weather check in the dock and app-switcher thingy (you know- command+tab). The freemium app reminds you that there are in-app purchases 1-2 times a day. I’m not as annoyed by it as another reviewer and frankly I don’t need/want what the additional $3 offers. Seems stable after a few weeks of usage. I say go for it!
