1. Left: your whole day, and how much of it is left
Left is a time awareness app for iPhone. Its Planner is a day view that pulls together what you already use, and its Time Left views show how much of today, the week and the year remain.
- One day view: Planner shows events from the Apple Calendars you choose, reminders from the Apple Reminders lists you choose, and Todoist tasks once you connect it, next to your habits, streaks, Aims and Ahead countdowns. A summary adds the weather and sleep, steps, workouts and mindful time from Apple Health.
- Not read-only: tick off a reminder or a Todoist task and the change is saved back; log a habit by tapping its symbol; add a reminder or calendar event with +. View as switches between a list, a week and a month.
- Planner widget: small, medium and large, interactive, so you can complete a reminder or a habit from the Home Screen.
- Time left today: the Today view and the Day widget show the hours left today as a grid, the Daytime widget fades the parts of the day that have passed, and the Minutes widget counts down the current hour.
- Nudges: a habit's Get a persistent reminder shows a Live Activity an hour before a time you choose if it isn't logged, and countdowns can show a Live Activity before they start or end.

How we chose
- Starting point: apps often named as Structured alternatives, checked on the US App Store on 20 October 2026.
- Kept: iPhone apps updated in the last few months that plan the day: visual planners, calendar-based time blockers and task managers with a day view.
- Left out: mobile apps that the developers describe as companions to a desktop app, apps not updated in over a year, and pure calendar apps.
- Sources: each app's own App Store page and Apple's lookup data, plus Structured's, Tiimo's, Akiflow's and Cultured Code's websites where noted. No paid placements, and no developer reviewed this page.
