Ignore what the person above me said! Yeah it might be confusing, but Ill tell you now: if you want to learn how to write katakana, this is the app for you!! Okay well, Ill help you: when you open up the app, click on the first of the three options there, and then click on whichever you want (its options like: a, i, u, e, o, or ka, ki, ku, ke, ko, etc.) and then itll teach you how to write it!!! Hope this helps!! (:
