5 stars: I've been learning Klingon for about 6 months now ... really excited to learn the script! This app works really well and is a great way to learn. I'm glad I have a bit of Klingon language under my belt first so I know how the characters sound as I'm leaning them.
4 stars: good for a start, but as you learn the alphabet this app is done and over unless more is added to advance your skills. Had issue with the Q and q which are two different letters but both displayed in Latin lower \
3 stars: Good but I wish there was an option to test all the lessons you've completed combined rather than only in the one you are in. Also lesson 5 has 'q' and 'Q' both displayed in lowercase making it impossible to know which Q it wants you to select.
3 stars: Please rectify the problem with distinguishing between the upper and lower case Q,s. It is even worse since the latest updates. Will get the full version once that is resolved.
5 stars: A very intuitive and well-designed system to quickly learn the Klingon alphabet. Outstanding.
5 stars: I am quite happy with the way this app has helped me progress toward learning the Klingon language.
5 stars: This is a wonderful and fun language to learn for us Nerds and Geeks who are huge Star Trek fans. Those who are not Star Trek fans can enjoy learning Klingon too.
4 stars: Since last time I tried the app, the capitalization issue has been rectified. MajQa'
5 stars: This is the best klingon tutor you could find...
