Stepple is the little pet that grows when you move — even a walk around the block is enough. Hatch an egg, pick a daily calorie goal that fits where you are right now, and watch your pet thrive as you move. Whether you're taking your first walk in years or training for a marathon, every step and every workout counts. Meet your goal and your Stepple gains hearts. Miss a day and they lose some — but a solid walk tomorrow brings them right back. START WHEREVER YOU ARE Stepple is built for anyone trying to move more. Pick a goal you can actually hit — it can be as small as a short daily walk. Beginners can cruise to their goal on steps alone. Experienced users can crush it with runs, lifts, cycling, or yoga. Either way, your pet is rooting for you. YOUR HEALTH IS THEIR HEALTH Stepple syncs with Apple Health to read your active calories, steps, workouts, flights climbed, sleep, and walking distance. Your daily goal is simple: burn enough active calories to keep your pet alive — and every step and every workout you log counts toward that goal, whether you're walking the dog, hitting the gym, or climbing a flight of stairs. A hearts bar shows exactly where your pet stands — thriving, content, tired, sick, or critical. FORGIVING BY DESIGN One bad day won't break anything. A missed day costs a heart, but tomorrow's walk earns half a heart back. Your pet only reaches the end of their story after several skipped days in a row — plenty of room to recover from a rough week, a busy trip, or a sick day. BUILD A STREAK Hit your goal today, tomorrow, and the day after — and watch your streak climb. Stepple tracks a per-pet streak and a global lifetime streak across every pet you raise, so even if one ends, your legacy carries on. A COLLECTION THAT FEELS PERSONAL 10+ unique creatures to discover, each with their own look and attitude. Every egg hatches with a randomly rolled color, so no two pets are alike — even of the same species. Some pets unlock only through dedication: one after earning enough goal days, another at a long streak milestone, and more surprises waiting to be found. EARN YOUR REPUTATION 20+ tiered accolades track running, swimming, cycling, yoga, hiking, strength training, dance, and team sports. Your pet develops an Activity Trait that reflects your dominant workout style — a living fingerprint of your fitness identity. Plus 15+ global achievements that persist across every pet you raise. MAKE IT YOURS 10+ pet color palettes, 20+ heart colors, and multiple free background gradients to start. Stepple+ subscribers unlock additional premium species, exclusive pixel-art backgrounds, parallax depth motion, custom heart shapes, glyph pattern overlays, and custom app icons. HOME SCREEN WIDGET An animated pet sprite lives on your home screen — watch it react to your daily progress without opening the app. Small and medium widget sizes included, free. THE GARDEN & THE GRAVEYARD Retired pets live in a pixel-art garden — tap any pet to revisit their story, or bring one back from retirement to keep going. Pets whose story has ended rest in a graveyard with tombstones marking their name, species, and lifespan. Every pet you raise becomes part of your permanent history. PRIVATE BY DESIGN No account, no sign-up, no ads. Your Apple Health data is read on your device to care for your pet and isn't shared anywhere — unless you turn on optional social features like leaderboards or friend sharing, which publish activity stats (like steps and goal progress) through Apple's CloudKit. You're always in control of what you share. --- STEPPLE+ SUBSCRIPTION Payment is charged to your Apple ID at purchase.
