每天一張卡,上面有一個問題。 大部分日記 App 給你一張空白的頁,然後你就卡在那裡,不知道要寫什麼。這個不一樣,它會問你一件事,一件你平常不會停下來問自己的事。 你寫的文字跟拍的照片都只留在這台手機裡,不會傳到任何地方去。 一天就一張 翻開之後就不能改了。 一開始你可能會覺得可惜,但這是重點。如果每一篇都能回去修,那它記下來的就不是你當時真的怎麼想,而是你後來比較希望自己怎麼想。 一天一張也是同樣的道理。希望這是一個每天一點一滴的習慣,慢慢更了解自己。 同一個問題過一陣子會再問你一次。 到時候你會看到「去年的今天,你是這樣回答的」。那個瞬間有點奇妙,你會看到自己改變了什麼,或是沒變。這是這個 App 和你一起慢慢累積起來的軌跡。 會問你哪些事 關於今天:從平常的日子裡,翻出一些你沒特別想過的東西 自我探索:你是誰,還有你在意的是什麼 工作與職涯:除了薪水,工作裡真正重要的是什麼 和另一半的日常:想像一下,你想要的是兩個人什麼樣的日常。還沒遇到也沒關係 我的理想關係:搞清楚自己要什麼,比遇到誰更重要 感情裡的自己:把鏡頭轉回自己,在一段關係裡,你會是什麼樣子 用照片記錄,即將推出。 跟朋友一起翻 原來你是⋯⋯是一包免費的同樂卡,90 張分成破冰、入水、深潛三層,由淺到深,剛認識或是老友都能聊。桌上的人一起決定要聊多深,再一張一張翻開。 聊點音樂是給一群喜歡聽歌的人的卡,一起放歌、一起聊。 這兩包都不會進你每天的卡堆,也不用寫字。手機放在桌子中間,輪流翻。 第一次打開的時候,可以先挑一包你最想要的免費送你。 這裡沒有的東西 沒有連續天數,沒有進度條,沒有人看得到你寫了什麼,也沒有讚可以按。 哪天沒寫也不會怎樣,不會有紅點提醒你、不會斷掉什麼。但當然每天寫一點更容易養成習慣。 你的東西是你的 答案跟照片都在你手機裡,不會離開。不用註冊帳號也能用。 要登入也可以,但登入只拿來同步你的提醒時間、開了哪些卡包這種設定。換句話說,伺服器上有你的偏好,但沒有你寫的任何一個文字。
