elevate is a free app offering three fun, practical games a day covering skills like mentally discounting prices, listening, and word recall--essentially everything you've become terrible at since graduating.
it was also apple's 2014 app of the year.
it’s so freakin’ gorgeous. i cannot get over how pretty and delightfully complex the graphics are. so if nothing else, play it for that.
personally, the brevity game is most rewarding. for each extraneous word or phrase you remove from sentences you earn a shape.
when you’re finished they combine to form an animal or dinosaur. if being rewarded in that manner for successfully shortening sentences doesn’t make your day, then i don’t know what will.
