The Recipe app keeps track of all your recipes, ingredients, and inventory. It will allow you to save ingredients, keep track of what you have, create recipes, and generate a shopping list based on what you have and what you are missing from a recipe. Also, the app allows to share your recipe to the public if you wish.
The Budget Tracker app is a mobile web application where you can manage your budget: you have a list of transactions associated with a category, so that you can see how much money you spent and on what.
