App For Calculating Cost Per Ounce When Shopping

I made an app for iPhone, iPad and Android that helps you calculate the cost-per-ounce of products when you are grocery shopping. It is great for comparison shoppers and couponers.


Scenario: Let's say there is a 32 ounce box of cereal for $5 on the shelf, and on the shelf below there is a 24 ounce box for $4. This app helps you quickly figure out which one is actually the better deal. In this case the $5 box is the better deal at about 15.6 cents an ounce whereas the $4 box ends up costing about 16.6 cents an ounce.

The app is very easy to use: Just enter the dollar amount and the ounces, push the button to calculate the cost per ounce, and there you have it!

Tip: Even though the app was specifically made to calculate cost-per ounce, you could possibly also get away with using it to calculate cost-per-pound, cost-per-gallon, and even cost-per-diaper if you wanted to.

However, there might be times that you want to specify the item to be selected based on something other than it's position in the list.

Parameters Sent by TinyWebDB in App Inventor for Android

TinyWebDB is a component in App Inventor for Android that lets your app communicate with a web page in order to set or retrieve values, rather than storing them on the phone itself. I wanted to know what the TinyWebDB component sends to the web page when it tries to set or retrieve values, so I used Kodingen this morning to write a PHP script that takes the form fields and values sent to the page and writes them to a file. Here is what I found: TinyWebDB.StoreValue sends these parameters: tag value TinyWebDB. GetValue sends this parameter: tag So if you write your own PHP page for TinyWebDB to connect to, you can know if TinyWebDB is trying to store a value if the "value" key exists in the $_POST array. If the "value" key doesn't exist in the $_POST array then you know that TinyWebDB is only trying to retrieve the value for the given tag. As an alternative to using the method outlined by Google , you could use TinyWebDB with your own script written in an
