I have tried or bought a lot of LMS plugins over the years. I always looked for something with a lot of features and sleek design out of the box. It seems that the main champions are (or were) LearnDash and LifterLMS with TutorLMS as a challenger. To my surprise I discovered a rare gem in Wordpress LMS space which is MasterStudy.

It ticked a lot of boxes:
✅ elegant and sleek design
✅ focus mode
✅ 8 question types (for me not enough but I'm counting on more; still some competition products don't have even that)
✅ assignments
✅ straightforward settings
✅ custom certificates, custom emails, drip content, point system
✅ integrations (Elementor, Zoom, H5P)
✅ my favorite: floating sidebar

Of course, there are some bugs but you can tell that about every software (especially LearnDash which I stopped renewing). What I like is: constant updates, asking customers about new features, app for mobile (I don't review it because it's still ahead of me).

To sum up, Master Study is a very good LMS plugin on its own. As an LTD it's a no brainer.
