Answer
Apple doesn't allow third-party apps to write events directly, but Screenshot to Calendar exports ICS files that drop into Apple Calendar, Fantastical, or any CalDAV provider. Capture once, choose “Export ICS,” and share the file however you like.
No. Apple does not offer an ICS write API for third parties. Instead, Screenshot to Calendar exports a standards-compliant ICS file that you can drag into Apple Calendar.
Yes. Before exporting, add attendees, descriptions, and reminders. Everything is embedded in the ICS file.
You can send events directly to Google or Microsoft 365 when needed and export ICS for Apple users in the same workflow.
