5 stars: Catalyst and Fluency Builder are great program to test my proficiency levels and build my professional communication skills. I have been using the program only for 2 weeks now and i spend about 30 minutes daily during travel. I can already feel the difference in my English pronunciation. I feel a lot more refreshed and confident at work.
5 stars: Rosetta stone is the best application to learn the language, I hope I can speak English fluently with rosetta.
4 stars: The lessons are great but best experienced on the desktop version, not on the app, since the app can be little buggy.
3 stars: The mobile app sometimes doesnt display the whole content and have to restart the whole lesson. Then some parts are cut and suddenly they dissapear.
3 stars: Can't watch some of the videos and some of the sections don't work on the phone app and computer. It's a great app but it also needs to work.
