Tap the quote
I thought typing to confirm a quote was getting a bit too easy. I didn’t want to build a totally different way to ask for confirmation, fearing that anything else could quickly get too gimmicky (solving math problems, waiting x seconds, etc.). I like the quotes because there’s a bit of meaning behind each one, so in addition to typing I created a “tap to complete the quote” interface.
It’s almost identical to Duolingo’s interface for putting words in order. The quote’s words are shuffled, with four decoys borrowed from the other quotes to spice it up a bit. You tap them back into order. The pills are all lowercase.
If someone prefers to type or tap, they can always switch modes on any quote confirmation screen, and their preference will be remembered for next time.
