Calendar ToDo
Read full descriptionHide full description
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.

Some notes are short. Others grow into chapters, plans and running logs you scroll past a hundred times. FoldNotes lets you fold the finished parts away, so a long note stays as small as the part you are actually working on. Every note is a plain Markdown file. No database, no proprietary format, no export step. Your notes sit in iCloud Drive or on your device, and any other app can open them, today or in ten years. It is also a real iOS app, written in Swift. Not a web page in a wrapper. It opens instantly, works offline, handles a hardware keyboard properly, and does not sit in the background eating your battery. FOLD ANYTHING • Collapse any heading or list item and everything beneath it folds away • Hoist a section to work on it alone, with everything else out of sight • Task counts stay on the folded heading, so you can see what is left without unfolding WRITTEN FOR MARKDOWN • Live styling as you type — headings, lists, quotes, code, links • Six heading levels, and GFM tables with a real table editor • Code blocks with syntax highlighting • Wiki-links [[like this]], with previews and automatic backlinks • Nested tags TASKS WHERE YOU WROTE THEM • Four states: to do, in progress, done and cancelled • Due dates and priorities written inline, in plain text • Assign them to a project and add context and comments • Counts roll up to the section above them BUILT FOR IPAD • Library, notes and editor side by side • Hardware keyboard shortcuts throughout • An inspector with outline, tasks, references, properties and a note graph • Scan printed text straight into a note with the camera FIND ANYTHING • Search every note, including regular expressions • Saved queries and database views across your whole collection • Daily notes with a calendar COMING FROM ANOTHER APP • Import from Bear or Obsidian in a tap • Or simply point FoldNotes at the Markdown files you already have MAKE IT YOURS • Light and dark themes, including Nord, Dracula and Catppuccin • Choose your body, heading and code fonts • Paragraph focus, sentence focus and typewriter scrolling Folding is not a formatting trick. A long document asks you to hold every section in your head at once; folding lets you put the finished ones down. That is the whole idea, and everything else here is built around it. Your notes will outlive this app, and every app like it. That is rather the point.
