Birthday Hub is on sale in the US WindowsPhone Store…it’s free now. It is a thanksgiving gift from me and it’s free until 11/28/2013. If you are a resident of the USA you can grab it now.
Birthday Hub has a 4.5 star rating in the german WindowsPhone Store and is in the top 100 over all paid apps.
Here is an example 5 star review from the german store at date 10/29/2013:
Very well done and sooo useful! For such apps it is worth to buy a smartphone.
Klasse gemacht und sooo nützlich! Für solche Apps lohnt es sich ein Smartphone zu kaufen!
