OpenTime
See your free time at a glance. On‑device and private, for iPhone, iPad, and Apple Watch.
Overview
What is OpenTime?
OpenTime is a private iPhone, iPad, and Apple Watch app that reads your existing iOS calendars on-device and shows your free and busy time slots at a glance. It collects no data, runs no servers, and uses no third-party analytics or advertising SDKs. Natural-language queries such as "tomorrow afternoon for 30 min" are interpreted locally by Apple Intelligence on supported devices.
