1) Would be nicer if it wasn't just an endless list of question cards. Maybe have new ones sliding in on the right, with answered ones going off to the left.
2) Visually separate the question, your answer, the correct/incorrect answer and the explanation.
3) Scores! How many right, how many in a right in a row, how did your guess compare with others etc
4) Social Interaction. Let me share my "best run in 60 seconds" and then let others see if they can beat me.
5) Pictures? Was just thinking you could have a 2x2 grid, with number and labelled picture of object in a colum, then you click on whether you think column 1 or 2 is the heaviest.
6) Stats - maybe on landing page or as commentary on your selections
"Did you know the weight of the Blue-whale has the most over-estimated mass"
7) Difficulty curve (or setting), feels a bit odd after you'd put some estimate into guestimating to just be asked "does a gorilla weigh more than 5 tins of beans?" Or maybe it just currently feels too-random. I might get 20 in a row, but I can't compare myself to somebody else who got another 20 in a row right.
8) "Is greater than" is nice, but simple <,> choice makes it too simple some times.
Maybe, "Which is closest to?" - which would give you multiple options to choose from.

But please don't decide that you need to shove a popup in my face repeatedly to persuade me to do so. I don't have "socials" and have no intention of sharing anything. Being obnoxious about it is a "Dick Move" imo
9) Coloured success/failure feedback, even just the words correct or wrong being coloured, it takes me a few moments to pick the result ouf of the new text being shown to me. This is why my bash scripts usually colour the output too.
Few (hopefully helpful) bits of feedback:
