The 14-day trial provides full access without a credit card, but after the trial users cannot add or complete tasks until subscribing.

Left is an iOS and macOS time-planning app that shows progress through the year, month, week, day, hour, minute, and life. Home Screen, Lock Screen, and StandBy widgets present those views, while Ahead creates countdowns for custom dates, imported calendar dates, and shared dates with friends. Planner combines Apple Reminders, calendar events, habits, streaks, weather, sleep, and workouts in one view. Users can track habits, streaks, and Aim manually or with Apple Health updates. The app includes an Apple Watch companion, a configurable Pomodoro-style focus timer, and fasting tools with reminders, widgets, Live Activities, history, and watch controls. Mood entries use Apple Health’s State of Mind data, and Left says it never uploads Health history. Widgets work offline; on-device data can sync through iCloud, while shared items use a Left account. The Free plan is free. Left Premium is a lifetime purchase with price shown in-app.
