This app has been updated to 64-bit. It covers the benefits and the deficiency conditions of 16 vitamins and 18 minerals. There are a total of 28 deficiencies covered. There are three game screens where the player matches a named button with a presented fact. There is one screen for vitamins, another for minerals and one for deficiencies. The game screens provide the number of right answers, wrong answers, and hints used. Tapping the "Hint" button reveals the answer. There are three study screens which allow the user to call up the fact about a particular vitamin or mineral by tapping the corresponding tile.
This app is provided FREE to the public. It may not be sold or distributed for profit. I am involved in helping the Parkinson's Disease community, so if you do want to show your appreciation, a donation to PD related cause would be nice. The program does not ask for any permissions, you do not need an internet connection to use the app, it does not collect any data, and it does not request any registration information. Enjoy and I hope you learn something. You can find more of my free apps by searching on Google Play Store for "Richard Carman" or "rtcgames".
