Overview
Very Good Calendar Sync is a macOS menu bar application designed to synchronize calendars across different providers (Google, Microsoft, Apple, CalDAV) with a strong emphasis on privacy. It runs entirely on your Mac, never sending your calendar data to external servers. The app is ideal for professionals juggling work, personal, and client calendars who want to avoid double-bookings without compromising security.
Acti is an innovative "agentic keyboard" for mobile devices (iOS/Android) that lets you type an intent, hold the Acti Bar, and instantly get results or perform actions across hundreds of apps and APIs. It uses AI to understand your intent and returns the right link, schedule, or action—without leaving your current conversation. Acti is built for power users who want to automate tasks like checking weather, finding restaurants, or querying Notion docs from anywhere.
