V2.0 In response to a negative review comment, I reworked the app so it now allows words of up to 12 chars. Also, revamped the dictionary to have 3 times as many words!! Finally, the app can now be moved to the sd card. V3.0 In response to user request, added sliders to allow user to specify timer rate and also to switch timer off. Also, user can now set the starting length of words when testing against the dictionary.
