代わり映えのない毎日に少し飽きていませんか? 新しいことに挑戦したいけど、きっかけがない。 人生で一度はやってみたいことがある。 YouInは、現実世界に「実績」というゲームのような仕組みを持ち込み、人生を少しだけ豊かに楽しむアプリです。 ■ 実績を解除しながら自分の経験を見つけていく 初めての一人旅、いつもと違う道を歩く、知らない本を読み切る——そんな「やってみたい」を実績として解除できます。 ■ 日々の小さなことも、実績になる 特別な挑戦をしなくても、いつもの毎日の中に実績はたくさんあります。ちょっとした失敗やアンラッキーな出来事さえも、視点を変えれば実績に。気づかないうちに毎日少しずつレベルアップしています。 ■ 積み重ねた挑戦がレベルという形に 実績を解除するたびに経験値が貯まり、レベルが上がっていきます。これまでの挑戦が、目に見える形として残っていく感覚を楽しめます。 ■ 広く浅く、いろんなジャンルに触れる 一度きりの人生、いろいろなことを経験してみたい。そんな気持ちに応える実績が揃っています。 ■ 狭く深く、好きなジャンルを極める グルメ・読書・資格取得・名所巡りなど、それぞれに特化したパックで、一つのことを極められます。 ■ あなただけの人生 誰かと競うためのアプリではありません。他人の目を気にせずに自分のペースで自分が納得できる経験を積み重ねていくことを大切にしています。 いろんな経験が毎日をわくわくさせてくれる。 そんな経験のきっかけを、YouInがそっと後押しします。
