Fast Memo is a very handy editor, like a pen and sheet of paper, always by your side. Just tap the Fast Memo icon, and you will be able to take a memo. If you run out of toothpaste tonight and need to buy some tomorrow, take a memo. A single word, toothpaste, should be enough to remind you. You don't need to enter dates or organize your memos. Unnecessary features and functions are a nuisance when you just want to take memos. All you have to do is simply keep entering keywords and scroll down. Fast Memo is software for this simple task. Saved logs can be searched not only by word search, but also by meaning with “AI Smart Search.” This feature lets AI find notes with similar meanings, even when the text does not match exactly like a word search. It uses the OS’s on-device AI and does not communicate with external servers. You can manage your notes by sending them to Google Drive, Evernote, iCloud, or Mail. You can add a widget to check your notes from the Lock Screen while shopping. By installing FastMemo 2, you can use two FastMemo apps. On iPad, FastMemo is also useful for writing slightly longer text with a Bluetooth keyboard. If you have any inquiries or requests, please email us.

Doit は「ひとつのタスクに集中する」ためのアプリです。 あらゆるタスクは、「始められないこと」こそが最大の障壁。始めさえすれば、終えられるかどうかは重要ではありません。 Doit では、マルチタスクを避けるために「今やるべきタスクをひとつだけ」登録します。あとはアプリが、あなたをそっと導きます。 たとえば「勉強する」というタスクを登録したら、こんなステップが表示されるかもしれません: ・足の指をモゾモゾさせて ・昨日の晩ごはんを思い出して ・机の角を触る 一見すると意味のない行動に見えても、それらはすべて「始める」ための準備です。身体や感覚をゆっくりと切り替え、やるべきことへ自然に向かわせてくれます。 脇道に逸れず、ひとつずつ。 本当に向き合いたいことだけに集中できるように設計されたアプリです。
