I made my Apple Watch's depth sensor do something deeply unserious. Apple ships a serious dive instrument in the Ultra and Series 10+ - and most owners never use it once. Plask points it at the bathtub: pixel-art rubber ducks swim on your wrist, and because the depth data is real, they dive when you do - live depth, max depth, water temperature. On depth-gauge watches it even launches itself the moment your wrist goes under. There's also Kungliga Badverket, a fictional Royal Swedish Bath Authority that issues 42 pixel-art certificates for your bathing career - first splash, dips below five degrees, and stranger things. Earn enough and the duck gets a hat. Free with the yellow ducks, forever. One purchase ($1.99 - no subscription, no account, it collects nothing) unlocks nine more scenes: sharks, jellyfish, aliens, Loch Ness, and surströmming - fermented Swedish herring, which felt right. Built solo in Gothenburg, Sweden. No bathtub? Demo mode drives the water with the Digital Crown. Scene ideas welcome - the engine makes new ones cheap, and Midsommar is already on the list.
