German grammar charts. Useful as a quick reference for people who are learning German.
This app is also useful in conjunction with other study materials. Having the tables open on your phone or android device so that you don't have to continually flick back and forth through grammar books while doing grammar exercises. It is also convenient for revision and study in short periods of time in almost any location.
If your studying German for travel, business, pleasure or the Zertifikat Deutsch (ZD) or any other reason, I hope that this app can be helpful for you.
