5 stars: Useful and responsive!!! Highly recommended for those who wants to improve English.
4 stars: On my phone, i couldn't load properly one of the exercises so I wasn't unable to do it, but it was ok on my computer
5 stars: It's a good way to learn English. I love it
3 stars: Many things work OK, but e.g. Matching exercises do not display and there is no way to complete them.
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.
3 stars: Directions are not clear. Not intuitive. Visuals aren't fully displayed.
5 stars: I love the short and intensive business focused content and activities. The modules are also built upon each other with incremental difficulty as we progress.
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.
3 stars: The lessons are good, but I'm not 100% sure how I ended up placed in the level I did... I KNOW I don't know this much Spanish. I shouldn't habe to google translate ...
