I have downloaded the latest version of the Rocket Languages app on my android device. At first I was so excited to finally have a portable way to do my lessons..
I used the various testing tools (Hear It, Write It... etc) and the buttons became green (which means I have successfully done the tests) BUT when I logged on to my computer account, all the work I had done on my phone did not show up, and I had to redo it all.. :( I'm really disappointed with the app.. I think its a really good idea and I hope that there will be a new update.

Hi RJ Developers,
The Rocket Japanese App on the iPhone is not very stable. For example, when I perform rating (testing) of Lesson 18.6 on Particles showing Conjunction of RJ Platinum. The app takes a very long time to respond to a rating and very often it closes and throw me out of the app.
Please investigate this issue. Thank you.
