IconCal

Overview

A calendar built around the emotional weight of icons. Two-way sync with Apple and Google calendars, native-feeling on every surface.

IconCal treats the calendar as a deeply personal surface. Custom emoji per event, real two-way sync with Apple EventKit and Google Calendar, and a calm interface that hides the complexity of recurring events and time zones.

I led the rewrite of the sync layer — Apple EventKit + Google Calendar API merged through a single conflict-aware reducer. Recurring events, time zones, the inbox of edge cases — all of it lives behind one calm interface.

On the platform side, I authored native iOS and Android channels in Swift and Kotlin to bring functionality that pure Flutter packages couldn't reach — calendar sync via EventKit and Google APIs, native notifications, background services, and location.
