so the simple answer is yes
To be more precise, I personally do most of my studies of Bunpro most of the time on the Computer as you can better view the various resources that explain in depth the different grammar points where it’s not clear right away. (Especially for new lessons)
The app is ok, but I would call it Beta rather than full blown. But I do know the programmers are working on it to get all the request into the app and some things fixed. I still use it tho when I’m on the road.
The great thing is that the admins are very active on the Forum and take every request, question, bug serious and as such Bunpro is getting constantly updated with community ideas, fixes and new content.
Also if, like me, you enjoy the SRS method of studying (like here on WK), then Bunpro is definitely for you, because it works exactly like that. It gives you for each grammar point various example sentences you are quizzed on and provides links to additional resources to read up on the grammar from different perspectives and explanations.
Lastly, just give it a shot. Do the free trial to see if it fits for you, there is nothing wrong with that
