Kei — Time Tracker

Kei is a simple, private time tracker for seeing where your day went. Start a timer, switch tasks when your work changes, and review your time later in a calendar or chart. Kei is built for personal logging - not teams, billing, surveillance, productivity scoring, or gamification. No account. No subscription. No ads. No tracking. No analytics. Your data stays on your device by default. If you choose to enable iCloud sync, Kei uses your private iCloud account so your time log can stay available across your devices. Features: - Fast start, stop, pause, resume, and task switching - Calendar view for reviewing past days - Simple charts by task or group - Groups, tags, and archived tasks - Lock Screen, Live Activity, Dynamic Island, Control Center, and Siri support - JSON export - Light and dark appearance
