HOW IT WORKS

Focus. Discover. Collect.

The timer is the beginning of the collection, not a separate layer added on top.

01

Focus

Start a focused session and give your attention to the task in front of you.

02

Discover

Complete the session to uncover an item from the fantasy world you are exploring.

03

Collect

Build a long-term compendium and gradually complete collections across different maps.

DESIGNED FOR QUIET FOCUS

A productivity tool with a world to return to.

Gamified focus timer

Focused sessions are the core of the experience, with item discovery and collection tied directly to completed focus time. Pomodoro-style routines also fit naturally.

Long-term collection

Collected items and map progress give completed focus time a persistent sense of accumulation.

No account

No Byeolgwawon login is required. There is also no friend list, ranking, PvP, or social feed.

No subscription

Focus Compendium does not use a subscription model.

No forced interruption ads

Ads are not inserted into the focus flow. The app uses optional rewarded ads that you choose whether to watch.

THE COLLECTION WORLDS

Six fantasy maps to explore.

Focus Compendium begins with six distinct collection worlds, each with its own atmosphere, items, and guardian. The collection is designed to unfold gradually rather than being completed in a few short sessions.

Additional screenshots and map previews will be added here before launch.

GUARDIANS OF EACH WORLD

A world that meets you back.

Each map has its own guardian. They appear as your journey through the collection unfolds, adding a quiet layer of story and personality to the world.

Guardian dialogue appears at key moments of progression rather than interrupting every focus session.
