Shield Nickel
Read full descriptionHide full description
This app was developed for the collectors of Shield Nickels. Please keep in mind that the app is intended for organizing and tracking your coin collection. Therefore it does not contain information regarding how to grade coins. One of the most enjoyable things to anyone who has the collector bug is keeping track of their collections. So, we have developed a series of apps to allow you to do just that. This app will provide the ability for the user to organize, track and manage their collection of coins. Images of each coin can be included with the collection. There is also a means within the app for the user to peruse all of the images in an entertaining manner. The app has three (3) color themes which help to make the app more enjoyable. A running tally of the cost for the entire collection is provided. A want list is also included in the app to allow you to ear-mark coins that you are searching for.

Verdict
The clearest difference is update cadence: BioMatrix at fortnightly against Shield Nickel's every 3 months. BioMatrix also leads on iOS requirement (15.1 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.
