I didn’t publish a lot of reviews in my Apps-section, but today I’d like to change that. The reason is my very high mobile phone bill, due to many calls to and from abroad.
Telekom offers an app with which you can easily check how much money you already spent and how many of your free minutes are left. I’m not a Telekom customer but rather decided to get a Simlock- and Netlock-free iPhone with Vodafone instead. Unfortunately, they don’t offer a similar app, as the iPhone isn’t sold by them. Nevertheless, if you’re guessing that someone else made the effort to create such an app, you’re right, it’s called Kosten Check D2.
Before I start writing about why I like it, I would like to pint out that a lot of people rated this app badly for it either not working at all or it having stopped doing so. Said that, to me it works fine thus far – knock on wood. 
The app nicely shows you how much money you spent and how much free SMS, MMS and/or minutes you have left. This works because the app connects with Vodafone.de’s QuickCheck. Obviously since the app doesn’t really do much more, one would not see the need for it, but I prefer an app over websites any day. The app is nicely made and as I mentioned, it’s working well with me. So if you are looking for an app that helps you controlling your costs without having to log onto Vodafone’s website, this one may be the one you are looking for.
