Grocery-Tracker is based on entering products by barcode, though it is not limited to that in any way. As such, GT has a database of over 500,000 bar coded products. On top of that, GT performs a look-up into Google for millions of additional bar-codes. There is also an option to include a Public database with over a million products. I know that most store brands are not included, but that is true of the other apps as well. There are probably between 10 and 100 million different bar-codes owned by thousands of different owners. Store brands tend to not provide their bar-codes to outside users, so they are typically not found.
   Grocery-Tracker deals with the products that you actually use. Not a list of thousands of products you don't use. Simply add what you actually use, quickly, easily. Once. Then use any one of Grocery-Tracker's quick find features to locate an item. Just a few taps, not typing the same thing again and again to find it to add to your list.
    Once scanned and added, all future scans of the product will find that product. Typically, users have between 300 and 600 actual products that they use.
   1. Those that include 50,000-100,000 existing products and require you to type part of the description every time you need to add something to your list.
   2. Those that require you to enter every product that you use manually.
  1. Those that are hybrids, with the ability to use a scanner to find products or directly enter the data.
    Grocery-Tracker is a Hybrid. When you look at some of the other Android apps in Category 1, one is over 7.8MB and the other is over 9.3MB. GT with the 500 some products that I use, including inventory tracking, price tracking and everything else, is only 1.91MB on my phone. And of that, only .16MB is the actual database.
    Shopping apps seem to come in one of three models.
