I am in the last (7th) Module of Level 1.
Generally, I like the course because it is very structured and explains language concepts very well. I like that there are dedicated grammar lessons that clearly concentrate on building your grammar foundations. A complete opposite of Duolingo which has no grammar explanations at all.
Some people find the humor in the course stale but I have no issue with it (not great but not bad either, tolerable).
The course does a pretty bad job in all flashcards and speaking (translation) exercises when the "you" word needs to be translated into German (translates to one of "du", "ihr", "Sie"). None of them are commented so you just make frustrating mistakes. There should be clear hints what is expected there.
The lessons are generally very long (often takes an hour to finish) which is not great. I think they should be broken up to smaller lessons that are no longer than 30 minutes. Due to the long time required to finish a lesson, I often cannot finish one during a single day and can only do the remaining part next day.
The Android app has been rewritten since I started the course and it is much better now (huge improvement there, congrats to the devs).
The price is also very hefty for the course. The ~250 EUR I paid should be some family package with 4-6 members (with separate progress tracking). An advertisement supported version would also be appreciated.

Thank for taking the time to share your thoughts on the course; it's great to hear that you generally enjoy the course. Regarding the flashcards and speaking exercises, there will be a notation visible to use as hints for you to know which version of the word "you" to use. We recognize that some lessons can be long but that is because we pride ourselves on comprehensiveness, the lessons will always save your place in them if you choose to leave and come back at a later date. We hope you continue to get the most out of your Rocket German course.
