The main menu shows 3 options:
1) 한글 쓰기: (han-gul sseu-gee) practice the stroke order for writing han-gul characters.
If you want the entire alphabet (or without adds) you have to buy the full version, which is $3.99.
2) 낱말 쓰기: (naht-mahl sseu-gi) writing vocabulary.
3) 한글게임: (han-guel game): (sorry...no pictures). For the "game," the audio give you one syllable at a time and you have to pick the right characters to spell out the multi-syllabic vocab word like balloon, camera, chick, etc. This would actually be good practice for my Korean-learning husband who recognizes the characters and their sounds.
