The clearest difference is in-app purchases: UJA App at none against Knowunity's 45. UJA App also leads on ads (none vs shown) and rating (5.0 vs 4.7).

UJA App holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Knowunity has 9.9K ratings behind it against 5, so its average is the more settled of the two.
