зажигалка = lighter (not lantern)
lantern = фонарь (not зажигалка)
верёвка (spelling includes ё)
Audio for наушник/наушники needs to be reversed; наушник is singular, e.g. earphone/headphone/headset; наушники is plural, e.g. headphones/earbuds
Some quirks I’ve noticed:
During the spelling exercises, there may be multiple instances of the same letter, e.g. two Д, but only one of them is the “right” one. If I choose the other, it counts as a mistake.
There may be different pictures with the same translation, e.g. two translations of парикмахер.
