Log Calendar
Manage tasks, plans & logs.
Free · In‑App Purchases
Plans, notes and records in one calendar. 3.1 adds handwriting on a day's page (iPad), a Mac app, timetables, exams and sharing with people you choose. Premium hides ads.
Calendar and daily records, all in one app.
Log Calendar is a smart calendar app that seamlessly integrates with iCloud and Google Calendar. More than just a schedule manager, it allows you to track and manage your daily records—such as weight, blood pressure, diary entries, step counts, and sleep—all in one place.
For "Task" management, the app focuses on a day-by-day approach rather than requiring you to set minute-by-minute times like traditional reminder apps. Simply write down, organize, and execute your daily tasks. It is perfect for both your professional and personal life.
With "Reminders," you can specify not only the due date but also the exact "start date" for when you need the reminders to begin. There is no need to open a separate reminder app; you can manage everything directly alongside your calendar.
We will continue adding the "Logs" you need. Let's build your ultimate "Life Log," keeping your daily records and schedules completely organized within a single app.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New
- A Note tab. Keep notes in folders, tag them, pin them and search them.
- Open a day's own page from the calendar. Write on it, and on iPad write by hand with Apple Pencil.
- Layouts made for iPad and for Mac. The Mac app is native.
- Timetables. Register periods, rooms, teachers and credits, then keep track of attendance and what is due.
- Exams. Record the dates and papers, the venue, the ticket number and what to take, and count down to the day.
- Choose what the Log tab shows: photos, anniversaries, workouts or statistics.
- More widgets for the Lock Screen and the Home Screen.
- Sharing. Share plans and timetables with the people you connect with.
- iCloud sync is now free for everyone.
Improved
- Delete your sharing account from Settings. Everything you shared goes with it.
- One colour palette across the calendar, easier to read in dark mode.
- Repeating reminders now follow the system Reminders app, so the next one is no longer created twice.
Fixed
- On Mac, a day's page listed that day's events twice.
- On Mac, the note list and the note itself were out of line.
- On Mac, the month grid could appear to start on the wrong day.
Notes and handwriting are free. Premium hides the ads and unlocks the extras.
