Create events. Edit ICS files. Export calendars. ICS Toolkit brings your calendar tools together on iPhone and iPad. Start with five clear actions: Create Events, Edit Events, Export Calendars, Import Calendars, and Server Mode. Choose a calendar on your device and save its synced events together in one ICS file. Repeating events keep their repeat rules and edited occurrences. Save the file to Files or share it with another app. Read-only calendars are supported too. Build events with notes, locations, links, time zones, reminders, and attachments. Set daily, weekly, monthly, or yearly repeats. Add an organizer and attendees to create meeting invitations for compatible calendar and email apps. Open an existing ICS file and choose the event you want to edit, even when the file contains multiple events. Search by title or location, then save the edited event as a separate file. Import events from single-event or multi-event ICS files into a device calendar. Review an event before saving or sharing it. Check its details, see compatibility messages, and inspect the generated ICS text. Autosaved drafts and reusable templates help you prepare events you create often. Use Server Mode to connect compatible CalDAV calendar apps to selected calendars on your iPhone or iPad. It works over a trusted local network while ICS Toolkit stays open and active. ICS files work with Apple Calendar, Google Calendar, Microsoft Outlook, and other compatible apps. Supported details vary by destination. Some information, including attendees and embedded attachments, needs to be shared as an ICS file instead of added directly to Calendar. Calendar export includes only events synced to your device. Apple's calendar access does not provide event attachments or all deleted repeating-event exceptions; deleted occurrences may reappear after import. No account is required. Your drafts and templates are saved on your device.
