Let’s Duck is a little pixel duck that lives on your Apple Watch and moves with you. I made it because most fitness apps made me feel like I was always behind. Rings to close, streaks to protect, numbers that turn red. I wanted something that just felt nice to open. So there’s no score to keep up with here. The duck is simply happy when you move, and happy to see you when you don’t. YOU DON’T HAVE TO DO ANYTHING SPECIAL Already use Apple’s Workout app, or another app that saves to Apple Health? Your duck picks those workouts up on its own. You don’t have to change how you work out. Just open the app now and then and say hi. NO PRESSURE, REALLY Take a week off and nothing breaks. Your duck won’t sulk. It’ll just be glad you’re back. If you turn on reminders, they’re gentle nudges like “lunch loop if you feel like it”, and they skip the days you’ve already moved. Rest days are part of it. A REAL LITTLE PET Your duck hatches from an egg, grows up, and has its own personality. Feed it, play, give it baths and tuck it in at night. It picks up your habits, too: early bird, night owl, water lover. WANDERLAND Every walk outside uncovers a little more of your duck’s own map of the neighbourhood, turned and drawn so your real streets stay private. Watch it uncover live as you walk, collect the places your duck finds, and decorate it all with the presents it brings you: flowers, benches, fountains, even a cottage. Friends from the games drop by to visit. MINI GAMES, GAME BOY STYLE Fishing, skipping stones, a pebble shooter, a sky chase with bosses, a rhythm game with kawaii songs and more, each with its own story, characters and 8-bit music. Listen to every soundtrack on the Jukebox. WHAT THE DUCK DOES ON A WORKOUT • Comes along on walks, runs, swims, rides, yoga, strength and lots more, waddling through its own little world while you go • Cheers your small wins with a happy hop • Draws a map of your outdoor workouts, colored by pace, and lets you press play to watch it waddle the whole route again • Shows the stats that matter: time, distance, heart rate, pace and calories • Breathes with you: rest a finger on the screen for a calm minute on a night pond • Lives on your watch face too, through complications and widgets Everything you record is saved to Apple Health. No account, no sign-up, no ads. FREE, AND YOU CAN EARN EVERYTHING Your duck and its workouts are free for everyone. Workouts you record in Let’s Duck earn feathers on the Pond Road, which unlock games, colors, outfits and more over time, just by moving. Locked games have free demos. Want it all right away, or want to support the app? Duck Premium is a one-time purchase that unlocks everything at once, plus a golden supporter collection. No subscription. Let’s Duck is made by one person. If you have an idea or something isn’t working right, I’d love to hear from you through the review. Hope your duck makes your day a little lighter.
