it's a bunch of applications themed around tingle, I really don't have much to say here. There's fortune telling, a timer, a calculator, a music box dancing thing, and a coin game to help you make decisions. Probably had a few niche practical uses when it first came out and everybody had their DSi on them, but nowadays it just remains a fun footnote in the zelda/tingle repertoire. I do like the non-zero chance that someone used the coin game to make an incredibly important decision, or that someone needed to use the tingle calculator to calculate how much money needs to be split evenly between the boys and girls when dining out in a group or something.
