Slumber Drift

Read full description

Last night's sleep decides today's sky. Slumber Drift is a text-based airship game powered by your real sleep data. Sleep well, fly far. Sleep short, drift close. Every morning is a new departure from the same dock โ€” but never the same voyage. โ€” HOW IT WORKS โ€” Connect Apple Health and set your sleep goal. Each morning, Slumber Drift reads last night's sleep and converts it into two stats: VOYAGE POWER โ€” How far your airship can fly. Determined by how many hours you slept relative to your personal goal. DREAM LUCK โ€” The quality of your journey. Shaped by sleep stage depth (Deep + REM). Apple Watch owners unlock the full ceiling; iPhone-only users reach a solid 0.8. Tap Launch Voyage. Watch the text log scroll: crystal earnings, encounters, events, and zone transitions โ€” all animated in 30 to 60 seconds. โ€” CHOOSE YOUR MOMENT โ€” At every encounter, you face a decision. Retreat โ€” lock in your crystals and end the voyage safely. Press On โ€” risk the encounter for more distance, better drops, and milestone rewards. The further you fly, the harder the encounters. A well-rested crew flies farther. A lucky crew survives longer. Sometimes the right call is to turn back. โ€” BUILD YOUR AIRSHIP โ€” Every voyage drops equipment. Fit your airship with Engine, Hull, and Compass pieces to push your stats higher. Rarity tiers: Common ยท Rare ยท Epic ยท Legendary Higher rarities carry more affixes โ€” and at Epic and Legendary, some of those affixes cut against you. A Legendary Compass might grant enormous crystal gains while quietly taxing your encounter odds. Choose wisely. Reroll affixes with Drift Crystals. Sell what you don't need. Curate a loadout for your playstyle. โ€” DREAM TONICS โ€” Spend Drift Crystals on consumable Dream Tonics. Each tonic lasts a set number of leagues before dissolving. Seven types, from route extenders to crystal multipliers to encounter shields. Mix and match active tonics before each voyage to shape the day. โ€” SLEEP STREAKS โ€” Consecutive nights of good sleep build a streak. Streaks unlock tiered buffs โ€” Gentle Breeze, Steady Wind, Strong Gale, and Eternal Trade Wind โ€” that multiply crystal earnings and improve encounter odds. A streak is worth protecting. โ€” MILESTONES โ€” Reach Lg 50, 100, 150, or 200 and the sky rewards you: bonus crystals and a guaranteed rare equipment drop. These aren't random events โ€” they're earned by flying far enough. โ€” HONEST DESIGN โ€” ยท No ads. No gacha. No pay-to-win. ยท One voyage per day. No grinding. ยท Your sleep data never leaves your device. ยท Read-only access to Apple Health. Slumber Drift never writes. ยท No server required. Works entirely offline. ยท One-time Pro unlock. No subscription. No expiration. โ€” SLUMBER DRIFT PRO ($4.99) โ€” Free users experience the full game loop. Pro expands the depth: ยท Up to 3 equipment drops per voyage (free: 1) ยท Inventory expanded to 24 slots (free: 8) ยท Up to 5 active Tonic slots (free: 2) One-time purchase. Yours forever. โ€” Privacy: Slumber Drift requests read-only access to sleep data via Apple Health. All data is processed entirely on-device and is never transmitted or stored externally.

Walk. Dig. Reveal. Turn every step you take into a treasure hunt. Your real-world steps power a pickaxe that slowly cracks open a rock โ€” and when you hit your goal, a hidden gem is revealed. The walk you were going to do anyway finally pays off. โ€” HOW IT WORKS โ€” โ€ข Walk. Your steps (read securely from Apple Health) chip away at the rock, stage by stage. โ€ข Dig. Watch the rock crack across multiple stages as your daily steps add up. โ€ข Reveal. Reach your goal and pull out the gem hiding inside. โ€ข Collect. Every gem lands in your collection โ€” 10 gems across 4 rarities, from common Rose Quartz and Citrine to legendary Moonstone and Diamond. Can you find them all? โ€ข Share. Export your reveal as a video or photo card and show off what you dug up. โ€” WHY YOU'LL KEEP WALKING โ€” โ€ข A real reason to hit your step goal every day โ€” your "silly little walk" is now excavation work. โ€ข Stock your extra steps and set a new rock whenever you're ready. โ€ข Home Screen widget shows your rock, your day count, and your progress at a glance. โ€ข Light & dark themes, with optional automatic switching by time of day. โ€” OPTIONAL UPGRADES (IN-APP PURCHASES) โ€” DigStep is free to play. If you want rarer finds, faster: โ€ข Silver & Gold Stones โ€” guarantee higher-rarity gems on a dig. โ€ข Gold Stones can even turn a word you "bury" into an AI-crafted gem, fossil, or relic. โ€ข Silver Plan / Gold Plan โ€” auto-renewable monthly subscriptions for unlimited premium stones (Gold also unlocks the stats dashboard). โ€ข Stats Dashboard โ€” a one-time unlock for monthly stats and personal bests. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage or cancel anytime in your App Store account settings. Terms of Use: https://digstep-api.itella.workers.dev/terms Privacy Policy: https://digstep-api.itella.workers.dev/privacy โ€” PRIVATE BY DESIGN โ€” โ€ข Your collection and progress stay on your device.
