A dungeon run while you sleep.

Equip your hero, set your sleep window, and tap Sleep. While you rest, your hero descends through procedurally generated floors. In the morning, watch the run unfold in a pixel-art replay and collect rewards.

Features

Equip. Sleep. Loot.

Sleep, then loot

Pick a hero, equip weapons and armor, and set a sleep window. iOS Background Processing runs a single deterministic simulation task while you rest. Wake up to a finished expedition.

Five hero classes

Each class has unique stats and sprite animations. Levels 1–50, equipment across five rarities (common to legendary), and an inventory with quick-sell and bulk-sell.

Procedural dungeons

Nine themed floors — stone halls, crypts, overgrown ruins, sewers, crystal caverns, lava pits, ice caves, arcane sanctums, and the void. Five rooms per floor with themed art.

Pixel-art replay

A SpriteKit replay scene shows every combat round, room entry, and loot drop with hand-animated sprites — walk, attack, idle, death — and atmospheric lore.

Curses & shrines

Curses like Fragile, Blinded, Hexed, and Cursed persist between runs until cleansed at shrines. Boss checkpoints let you resume from previously cleared floors.

Codex

Browse every monster, boss, room type, and world lore entry you've encountered. 90 room descriptions, 7 world lore entries, in-app search.

Sleep-aware depth

Optionally read Apple Health sleep data to scale dungeon depth to how long you actually slept. Nothing leaves your device.

No network. No accounts.

Stores everything locally in JSON. No analytics, no telemetry, no notifications. Background simulation runs once, then stops.

Privacy

No network. No accounts. Just dungeons.

Sleep Dungeon never makes a network request. The game world, your character, your loot, and your codex live entirely in JSON on your device. Optional HealthKit reads stay local.
