Every step shapes a crystal. GemStep is a step counter and gentle growing game that turns your daily walks into a one-of-a-kind 3D crystal — right on your Home Screen. Choose a starting shape and scene, go about your day, and watch new crystal columns emerge as your steps add up. Every crystal is created from its own unique seed, giving it a form you can rotate in 3D, replay from the beginning, customize, collect, and share. KEY FEATURES - Automatic Step Tracking: Connect to Apple Health through HealthKit and let GemStep read your step totals automatically — no manual input needed - Living 3D Growth: Watch your crystal gradually change shape as you walk, with new columns appearing throughout its growth - Home Screen Widgets: Add Small, Medium, or Large widgets and keep your crystal and latest progress close by - One-of-a-Kind Crystals: Each crystal combines its own seed, shape, color, clarity, and scene — no two journeys have to look the same - Growth Time Machine: Replay your crystal’s journey from its earliest form to where it is today - Personal Collection: Save completed crystals, give them names, mark your favorites, and build a collection shaped by your walks - Customize Your Crystal: Change colors, switch scenes, or try a new shape without resetting your growth progress - Create & Share: Turn your crystal into a high-resolution image, wallpaper, transparent PNG, or six-second rotating video - Gentle Progress: No streaks to break, no wilting, and no punishment for missing a day WHY GEMSTEP Most step counter apps only show you numbers. GemStep turns those steps into a visible reward — a beautiful 3D crystal shaped by your own journey. It feels like a game, but all you have to do is walk. There are no strict daily goals and no pressure to maintain a streak. Your crystal simply keeps growing whenever you do. Perfect for anyone bored with traditional pedometers or looking for a relaxing, visual reason to walk more. PERFECT FOR - Anyone looking to make a daily walking habit more enjoyable - People who find traditional step counters boring - Widget lovers who want something beautiful that changes on their Home Screen - Fans of crystals, relaxing growing games, and digital collections - Anyone who prefers gentle motivation without streak pressure HOW IT WORKS 1. Choose a starting shape and a scene for your crystal 2. Connect to Apple Health for automatic step tracking 3. Walk through your day — commute, explore, run errands, or take a quiet stroll 4. Follow your crystal’s latest growth in GemStep or from the Home Screen widget 5. Rotate it in 3D, replay its growth, customize its appearance, or share your creation 6. Add the completed crystal to your collection and begin growing another HEALTHKIT INTEGRATION GemStep uses HealthKit to read step totals from Apple Health, so you do not need to enter steps manually or keep the app open while you walk. Walk with your iPhone or any compatible device that saves steps to Apple Health, and GemStep applies the latest available totals when it syncs. GemStep requests read-only access to step totals. It does not read walking routes or precise location, and it never writes data to Apple Health. HOME SCREEN WIDGETS Add a Small, Medium, or Large GemStep widget to keep your crystal nearby. See its latest appearance and step progress without opening the app. Widgets update throughout the day according to the refresh timing allowed by iOS. GET STARTED Download GemStep and turn every walk into a one-of-a-kind 3D crystal.

Verdict
The clearest difference is in-app purchases: 散歩で世界旅行 at none against GemStep's 3. GemStep's advantage is update cadence (daily vs every 4 days) and iOS requirement (18.0 vs 26.2). On price, ads and device support there is nothing between them.
