Summer Check

A quick, shareable summer-food personality test made for Apps in Toss.

Summer Check welcome, question, and result screens

( THE IDEA )

A small test
made to be shared.

Summer Check began with a goal to gather organic viral attention through something people could finish and share in a moment. A simple personality test felt like the right format, and Apps in Toss offered a familiar place for many people in Korea to try it.

Ten quick A/B choices turn into one summer-food personality, designed to make the final result easy to pass along to friends.

( BUG FIX — 2026.07.24 )

Continuous taps could change the result.

Rapidly tapping an answer button could desynchronize the answer count and question number, skipping a question and producing different food results for the same choices. chooseAnswer now accepts only the first selection for the question on screen and ignores extra input while moving to the next question. The same answer sequence now always produces the same food result.
