What are some good iPhone apps that aren't well known?

I look at the main App Store page every day, so i was wondering if anyone knew of any really good/fun apps that not many people know about (a good example is Graal Online Classic).

Media Burner is a great free app you can use to download music from YouTube for free and listen to them whenever and wherever.

  • What should I do so that my iphone connects to known Wi-Fi automatically? So recently I reset my network settings as someone said that I should do that to lose a problem (my phone was giving me two text alerts when I've only received one. Yes I checked the notifier already which I put to never) so that problem is solved but now everytime I get home, I have to key back in my Wi-Fi password whereas last time it would automatically connect. I've been resetting my network settings a few times but nothing has changed.
  • What's a good, but lesser known anime out there? I've watched all of the largely known one's, such as Naruto and One piece, so I'm looking for some new options. Also: do you know a site I can watch them on my iphone?
  • What are some places that can fix iphone screen cracks very well for a cheap price? My dog broke my front screen. Now it has a large crack on the left side. I don't hav alot of money, and i want it to be fixed as good as new. It is an iphone 4 by the way. Do you know any places that can do that?
  • What are some good iPhone 5 cases that aren't bulky? I know that the otterbox is very bulky and I'm not a very big fan of that. I'm looking for suggestions of cases that are not big and clunky but still provide protection. I'm a 15 year old boy so I would prefer black, grey, or clear cases.
