Ingrescale

Easy to use rule of three calculator
Ingrescale will let you calculate the rule of three in a easy and fast way for multiple values at once.
This comes specifically handy when recalculating ingredient lists and therefore pairs great with Memocipe for your kitchen application.

Save, Load, Repeat
It is possible to save, load and share your calculations to reuse them later on.
This will not only save a lot of time when you need to recalculate your favourite recipes once again,
but it will also allow you to store your recipe's ingredient list when you don't need fleshed out instructions in your recipe.
