弦交換メモは、所有しているギターごとに弦交換のタイミングを管理できるアプリです。 複数のギターについて、ギター名、メーカー、型番、メモ、現在使用中の弦、次回交換予定日、交換ルールをまとめて記録できます。 弦交換の管理方法は、 「日付指定」 「周期指定」 の2種類に対応。 日付指定では、次回交換予定日を自分で設定できます。 周期指定では、前回交換日を基準に、日・週・月単位で次回交換予定日を管理できます。 交換時期が近づくと、ギターごとに3日前通知と当日通知を設定できるため、 「そろそろ弦を替える時期だった」 「前回いつ交換したか忘れた」 を減らせます。 弦交換を記録すると、交換履歴として交換日を保存できます。 周期指定の場合は、次回交換予定日も自動で再設定されます。 【主な機能】 ・ギターの登録 ・ギター名、メーカー、型番、メモの管理 ・現在使用中の弦を記録 ・弦名の自由入力 ・よく使う弦候補の管理 ・日付指定、周期指定による交換ルール設定 ・日、週、月単位の周期設定 ・弦交換日の記録 ・次回交換予定日の自動更新 / 手動更新 ・3日前通知、当日通知 ・期限が近い順のギター一覧表示 【こんな人におすすめ】 ・複数のギターを所有している ・弦交換のタイミングを忘れやすい ・前回いつ弦を交換したか記録しておきたい ・ギターごとに違う弦や交換周期を管理したい ・自分のiPhoneだけでシンプルに管理したい 弦交換メモは、日々のギター管理を少しラクにするための弦交換記録アプリです。

Task Chart is a planner app where your plan is written on one big sheet of paper. ■ One sheet Goals and tasks live together on a single sheet, nothing abbreviated. The phone screen is a window onto that paper. Pinch to zoom, pick a task up with your finger and rearrange it — you see where everything will settle before you let go. ■ Day by day Tap a cell and record the day in one stroke — a check, or a number. The row and the day light up in a quiet cross. Past days turn like a scroll under your finger. ■ Quiet by design No advertising. No tracking (only anonymous usage counts, which you can turn off in Settings). No badges, no streaks, no flames. Just paper and ink. ■ What you write is yours The notebook is stored on your device only, and you can export it to a file at any time. If you stop subscribing, everything you wrote stays readable. Nothing becomes unreadable. ■ About the subscription Writing — creating and editing tasks and records — requires the Task Chart subscription (US$0.99/month or US$11.99/year; prices vary by region). Reading and exporting are free without one. The first 14 days are free for new subscribers. Unless you cancel at least 24 hours before the free period ends, your Apple ID is charged for the period you chose, and it renews automatically until you cancel. You can cancel any time in iPhone Settings. If you purchased the earlier paid version, please contact support.
