思ったこと、やったこと、これからやること。フォルダに振り分けることも、どこに置くか迷うこともなく、書いた順にただ並びます。Logline は、一日をそのまま一本の線として残すための記録アプリです。 - 書くことは、ずっと無料 記録の作成・編集・削除と、過去ログの閲覧に上限はありません。「30日より前は読めません」のような制限も入れません。 - 端末の中に残る 記録は端末の中のデータベースに保存されます。同期を使わないかぎり、書いたものがこの端末から出ることはありません。電波がなくてもそのまま書けます。 - ノートとタスクは地続き チェックボックスを付けられる記録が「タスク」です。予定を立てる道具ではないので、繰り返しもリマインダーもありません。書く、終わったらチェックする、あとで読み返す。それだけです。 - あとから探せる 全文検索と、種類(ノート/タスク)・タグでの絞り込み。過去の記録は遡って読み込めます。 - 持ち出せる Markdown / JSON / CSV で書き出せます。書いたものは、いつでも自分の手元に取り出せます。 - Mac とつながる Logline Sync に加入すると、iPhone で書いたものが Mac のタイムラインにも並びます。オフラインで書いたぶんは次につながったときに合流し、同じ記録を両方で直したときは新しい編集が残ります。 - プラン Logline(無料) 記録は無制限。全文検索、タグは5つまで、ライトモードとデフォルト配色。 Logline Plus(買い切り ¥1,200) タグ無制限、ダークモードと配色(オーシャン/サクラ)、画像の添付、書き出し。 Logline Sync(サブスクリプション) Plus のすべてに加えて、Mac と iPhone の自動同期。 - サブスクリプションについて Logline Sync は自動更新サブスクリプションです。 ・Logline Sync(月額): ¥300 / 1か月 ・Logline Sync(年額): ¥3,000 / 1年 お支払いは購入確定時に Apple ID アカウントに請求されます。現在の期間が終了する24時間前までに自動更新をオフにしないかぎり、サブスクリプションは自動更新され、同額が請求されます。購入後は App Store のアカウント設定からいつでも管理・解約できます。 解約しても、これまでに書いた記録が消えることはありません。 利用規約(EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Logline の利用規約: https://loglineweb.netlify.app/terms.html プライバシーポリシー: https://loglineweb.netlify.app/privacy.html
