Learn History app for iPhone and iPad

"Learn History" is a tool to learn events and dates from different eras of History.
You first have to choose the subject you want to learn. There is presently 10 different subjects.
For each subject there is about 120 events and their respective dates.
The first step asks you to identify 3 events between 6 presented for a given time period.
The second step asks you to pair these selected 3 events to their specific dates.
These are the subjects presently available:

- American Civil War
- American Revolution
- Ancient Civilisations
- French Revolution
- Great Explorers
- Life Evolution
- Napoleon
- Space Pioneers
- World War I
- World War II

Subjects will be added in the subsequent versions of the App. If there is a particular subject you would want me to add, please feel free to contact me.
The App also keeps track of what you have learned and how well you have learned it. You can start over a particular subject as much as you want until you are satisfied with the depth of your knowledge.
You earn credits for each good answer and loose credits for each bad answer. If you are out of credits you can buy some or listen to a video ad and get credits for free.
