Plask
Rubber ducks. Real depth.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Tilt your wrist and the water sloshes. Plask now moves with you, and Kungliga Badverket has opened a front office on your iPhone. The ducks remain on duty.
Plask (Swedish for "splash") turns your Apple Watch into a tiny aquatic theatre.
Pixel-art rubber ducks paddle around while you bathe or swim. On a watch with a depth sensor (Apple Watch Ultra, any generation, or Apple Watch Series 10 and later) the scene reacts to your real depth: ducks dive when you do, with your live depth, max depth and water temperature at the bottom of the screen.
The water's temperature shows up in the scene itself. Cold enough and the surface ices over, scarves come out and breath fogs in the air; hot enough and it steams, bubbles and everyone lounges. Ordinary lake water looks exactly as it always has — the reactions are saved for an ice hole or a hot tub.
The scenes feel your wrist, too. Tilt it and the water leans; flick it and it sloshes, heaps up against one side and rolls back. The shore and the sun tilt with you while the water moves against them. Ducks get thrown about, Johnny Castaway clings to his palm, and the surströmming tins go airborne.
On watches with a depth sensor, Plask can even open on its own the moment you get in the water. Enable it under Settings > General > Auto-Launch > When Submerged, and the app walks you through the steps.
On dry land? Tap "Try a Dive" and drive the water with the Digital Crown from the couch. Swipe sideways and the crown dials the water temperature instead.
Between baths, the duck has an off-duty life. It lives on the launch screen, where you can drop in on it, feed it, hand it a toy and put one of your earned hats on it. It is a tjänsteanka — a government-issued service duck — so it keeps a dossier, a provisions journal, and files a report about your absence whenever you have been away. It cannot starve, cannot sulk and has never once been disappointed in you. There are no meters, no streaks, and it will never send you a notification.
Every swim is also on the record: Kungliga Badverket, the (fictional) Royal Swedish Bath Authority, issues pixel-art certificates for your aquatic accomplishments — depth, duration, cold water, dawn dips, looking after the duck, and stranger things. Earn hats for your duck. Browse it all in Arkivet, your trophy room. Certificates sync through iCloud, so a new watch keeps your archive.
NEW: PLASK FOR IPHONE
The Authority has opened a front office on your phone. It is optional — the watch app needs no iPhone — but it is where the paperwork goes to be admired. Play every scene on a virtual watch in the Pool and tilt the phone to slosh it. Read your certificates and field reports in Arkivet and share them as story-sized cards. Visit the duck's file and its wardrobe. Put the duck on your Home or Lock Screen. The phone only reads what your watch has already filed; it never writes, and it collects nothing.

Plask now moves with you, and Kungliga Badverket has opened a front office.
• Wrist motion. Every scene now feels your wrist. Tilt it and the water leans; flick it and the water sloshes, heaps up against one side and rolls back; shake it and it chops. The world tilts with you — sun, shore, jetty — while the water does what water does. Ducks get thrown about, Johnny Castaway clings to his palm, the surströmming tins go airborne, and the Vasa keels over, as is tradition. Free for everyone. Settings › Display › Wrist Motion turns it off, and so does Reduce Motion.
• Plask for iPhone. Optional, free, and entirely beside the point: the watch app still needs no iPhone.
– Pool: all 14 scenes on a virtual watch. Tilt the phone and the water sloshes, drag to dive. A preview — the real thing is on your wrist.
– Arkivet: your certificates, field reports and the duck's paperwork, each shareable as a story-sized card.
– Duck: the tjänsteanka's file, its journal and a wardrobe. It keeps office hours. Do not pester it.
– Office: watch status, the auto-launch guide, Premium and Restore Purchases.
– A duck widget for the Home and Lock Screen. Awake by day, asleep at night.
One purchase unlocks Premium on both.
• The demo thermometer. In Try a Dive, swipe sideways or tap the DEPTH badge and the crown dials the water temperature instead. Ice holes and hot tubs, from the couch. Dialed temperatures earn no certificates; the Authority checks.
Still one purchase, still no subscription, still collects nothing.
