Turn your calendar events into a progress log you can review later. Calendar ToDo reads your calendar events and lets you record completion, progress, and reflection inside the app—without creating, editing, or deleting your calendar events. Because Calendar ToDo works with events shown in Apple’s Calendar app, you can use calendars from iCloud, Google Calendar, Outlook, and other accounts synced to your iPhone. Tap the Done button on the right to record completion immediately. Touch and hold an event to open the progress card and choose a percentage from 0% to 100% in 1% increments. Changing and saving the percentage also records Done and the first reflection suggestion shown. This updates any previous reflection selection. You can choose a different suggestion from the same card. Done records that you carried out the plan; it does not necessarily mean you completed a larger goal. If you worked on a plan but felt no progress, you can record 0%. Opening the card alone does not save a record, and clearing progress keeps Done. Your saved records appear in completion history, graphs, and reports for later review. On supported devices and languages, Apple Intelligence assists on-device event classification and Weekly Report insights. When Apple Intelligence is unavailable, completion, reflection, and category review and correction remain available. Key Features - On supported devices, Apple Intelligence assists event classification - View events from Apple Calendar, iCloud, Google Calendar, and Outlook without editing them - Check events and progress from the Monthly Calendar - See recorded progress in the background of each event row - View the month calendar and the selected day’s events side by side on an unfolded iPhone Duo - Browse months and expand a week in a larger Home Screen calendar widget to see events and completion status, then open a selected day in the app - See adjacent completed dates in multi-day events as a continuous completion band - Review completion history and the next two weeks of schedule changes with a small or medium Home Screen Heatmap widget - Browse today's events and mark them Done with one tap - Touch and hold an event to record progress and reflection - Review and correct each event's category from event details - Review schedule load, outcomes, progress, and reflections in the Report section of Analytics - Get end-of-event reminders with Done and 1-hour snooze actions - Notice schedule changes such as new events, time shifts, and missing routines - Sync completion and progress records across devices with iCloud Calendar ToDo is for people who already plan with a calendar and want a simple way to look back on what they completed, how far they progressed, and how the week went. Some features, including detailed reviews of past weeks, are available with Calendar ToDo Plus (monthly or yearly). Eligible subscribers may receive a 1-month free trial with the monthly plan.

1分の習慣

Features
Read full description

このアプリでは、タイマーを最大5分までしか設定できません。 なぜか? 一度始めた行動は、続けやすくなるから。 「1分だけ」のつもりが、気づいたら5分、10分。 大事なのは「長くやること」ではなく「始めること」です。 — ■ 3日坊主は「意志力」の問題じゃない 習慣が続かない本当の原因: ・いつやるか決まっていない  「毎日やる」だけでは、いつまでも始まらない ・何をするか具体的じゃない  「筋トレする」では、何をどれだけやるか毎回迷う ・目標が大きすぎる  「毎日30分」は、3日目に負担になる 「1分の習慣」は、この3つを仕組みで解決します。 — ■ 3つのシンプルな仕組み 【if-then planning】 「朝コーヒーを淹れたら、ストレッチをする」 いつ・どんな状況で・何をするかを事前に設計。 心理学者Gollwitzerの研究で、目標達成率が2〜3倍になることが実証されています。 【3ステップ分解】 やることを3つの具体的なステップに分解。 「次に何をすればいいか」を考える必要がなくなります。 【1〜5分タイマー】 始めるハードルを極限まで下げる。 1分から設定できて、最大5分。それだけでいい。 — ■ 主な機能 ・if-then planning:「いつ・何を」を設計して通知でリマインド ・1〜5分タイマー:始めるだけ。あとは流れに乗る ・カレンダースタンプ:やった日がひと目でわかる ・完全オフライン:アカウント登録不要。データは端末内に保存 — ■ こんな方に ・何度も3日坊主を経験している ・習慣化アプリを試したけど、結局続かなかった ・やりたいことはあるのに、始められない ・「頑張る」以外の方法を探している — 頑張らなくていい。仕組みに乗るだけ。 あなたのペースで、1分から。
