Good idea, disappointing product

The idea that I dont have to be on Skype and I can know when my sister (who lives in Italy) comes on sounded great, but as it turns out this app is just so basic its disappointing. $3.99 is VERY expensive in the App world, and to realize you get NO options and features makes me really upset I purchased this at all.
There are the problems mentioned by another user, such as the fact that Skype takes a while to start, which makes this app send you an error message and it doesnt re-try to connect on its own once Skype has started.
For myself I didnt realize that Skype had to be on 24/7 for this to serve any purpose at all. I dont know to use power and space having Skype on AT ALL TIMES, and I just assumed that it could do the job while having Skype off or at least "dormant." But now I see that I basically have to have the app on for the rest of my life for this to serve any purpose.
It doesnt seem either like the developers take suggestions and work on them, because the same problem the other user mentioned are still there.
This isnt worth 4 bucks, dont buy it!
