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. [Key Features] Monthly calendar view (Syncs with iCloud & Google Calendar) Task management Track weight, blood pressure, steps, and sleep Diary feature Dark and Light mode support Custom color settings for each category [Premium Features] Enjoy a comfortable, ad-free experience with our monthly, annual, or lifetime (one-time purchase) plans.
