Plask turns your Apple Watch into a tiny aquatic theatre: pixel-art rubber ducks that dive when you do, your real depth on screen, and a duck or ten. With premium, you get sharks, the Loch Ness-monster, a castaway, surströmming, and more.
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.
love the idea of actually using the depth sensor for something other than diving logs nobody looks at twice. question though - I've got a regular Series 9, not an Ultra or Series 10+. is demo mode basically the whole experience for me (crown-driven water, no real depth data at all) or is there some lesser version that still reacts to being near water/humidity even without the proper sensor
Thank you,
We need more fun apps. I miss the Talking Moose, Oscar the Grouch, MacPuke, Racter... And what else was there for the old Mac? Now everything is so effin’ serious…
