【マジシャン用 / For Magicians】 このアプリはあたかもあらかじめ相手が考えていることを Google 検索していたように見せることができるアプリです! このアプリの操作方法は以下の通りです。 1. 設定画面で好きな URL を設定します(例えば、「東京」というワードで Google 検索した際の URL) 2. 上記で設定した URL には識別するための番号も設定されます。(「東京」の URL は 1 のようなイメージです。) 3. iPhone のデフォルトの待ち受け画面に非常に似た、アプリ内の疑似待ち受け画面で 1 番が割り振られている場所をタップ(タップする場所は画像を参照)し、普段のロック解除のように上方向へスワイプします。 4. スワイプすると、あら不思議「東京」というワードで検索された後のブラウザが表示されます。 ---------- This app can make it seem as if you have already Googled what the other person is thinking! Here is how to use this app: 1. In the settings, set your preferred URL (for example, the URL when you Google search the word "Tokyo"). 2. A number is also assigned to the URL set above for identification purposes (imagine the URL for "Tokyo" is assigned the number 1). 3. Tap the area assigned the number 1 on the app's pseudo-lock screen, which looks very similar to the iPhone's default lock screen (refer to the image for where to tap), and swipe upwards as you would to unlock normally. 4. Upon swiping, voila! The browser appears, displaying the results of the search for the word "Tokyo."
