Only Calendar is a simple, focused calendar for people who want to plan clearly without clutter. Create events with notes, locations, links, colors, reminders, durations, and repeating schedules. Switch between Month, Week, and List views to see your plans from the right angle. Use search, quick filters, color filters, archives, and undo actions to keep your calendar tidy as it grows. Only Calendar also supports basic ICS import and export, JSON export, text export, Home Screen and Lock Screen widgets, app language selection, local notifications, and private iCloud sync for Pro users. Only Calendar Pro is a one-time purchase with no subscription. Pro removes the 25 active-event limit and unlocks private iCloud sync through your personal iCloud account, including event details, reminders, repeats, colors, locations, links, notes, and archived events.
