Number vs. percentage of lessons done
I've noticed a difference in the web and android version of duolingo where the current progress of a module is measured as a percentage in the web version but as a number in the android version (eg. 50% vs. 5/10).
I'm not really a fan of the percentage since you don't really know how many lessons there are in a module, is there any way to change this? What are your thoughts on this?
