Nundina is a free calendar app that combines your own schedule with public calendars you subscribe to. Instead of typing in the next match, the next release or the next public holiday, you subscribe once and the dates arrive on their own.
Subscribe to any of the 200+ aggregated calendars, import and export ICS files, set reminders by email or push, share events with friends, and ask the built-in AI assistant to create or find events in plain language. Free to use, with an optional Pro plan at 1 USD per month.
