Hi, guys! There is a gap in Korean language learning materials on App Store, so I came up with the idea of this simple grammar reference. There's a clear and self explanatory 3 page mockup attached. About 200 grammar patterns grouped in categories. First, user selects a category and then a grammar pattern within that category. For each grammar pattern there're an explanation and some examples with translations. For each grammar pattern a user can make a note or check it as learned. All design elements, like icons, colors, backgrounds will be done by myself. Some basic font like Helvetica would work perfectly. Also, I'm planning on several content updates for this app and create more apps on Korean grammar and vocabulary. Feel free to inquire for more details if you're interested.
