Android Baking App
I was looking for an android app to store recipes in baker's percentages and automatically scale the quantities. The Baker App does this and also handles imperial/metric conversion very elegantly and generally looks pretty.
It is only just out and so far there does not seem to be any way to export or import recipes which is a bit of a pain as I would like to have my tablet and phone in sync without having to enter everything twice.
But, the app is free and they seem very open to sugestions for improvments so it is worth a spin if you are an android user.
