STUDIO INPUT

  • Toss mini app
  • Habit interaction
  • Share-card experience

01

Brief

Make a daily ritual feel lighter: complete one deliberately small action, then pick up one piece of imaginary luck.

02

Daily loop

A mission is revealed, completed on trust and converted into a single animated luck collectible. Local-date logic keeps the reward to one per day.

03

Record

The device stores completed dates and variants locally, then turns them into a total, current streak and recent seven-day view.

04

Sharing

After completion, the app generates a visual result card for the native share flow, with a downloadable fallback when direct sharing is unavailable.

05

Build and submission

The React, TypeScript and Vite build is configured with Apps in Toss Web Framework 3.0.1 and produces an Apps in Toss submission bundle. With no verified public store destination attached, this record remains BUILDING.
