Left is a time-awareness app built on one idea: your time is limited, and seeing it changes how you use it. Left turns time into something you can see, then helps you act on it with habits, streaks, countdowns, and a planner for your day. TIME LEFT See where you are in the year, month, week, day, hour, and your life. Each unit is a symbol; the past dims, what remains stays in view. Your life in weeks, year progress, and life progress, made tangible. Choose dots, symbols, colors, and layouts. A quiet, honest way to face limited time without it becoming morbid. HABITS, STREAKS & AIMS Left is a habit tracker for the person you are trying to become. Build habits on any schedule: daily, several times a day, weekly, monthly, or custom. Track streaks and protect them, count the days since anything that matters, and set reminders so nothing slips. And you don't have to do it alone: share a habit or streak with a friend, keep each other accountable, and send kudos, cheers, and encouragement when it counts. With aims, you have a flexible goal tracker for anything you can count, helping you build up or cut down. Stay on track and see your progress every day. AHEAD - COUNTDOWNS & DATES Add the dates that pull you forward: trips, birthdays, holidays, anniversaries, weddings, deadlines, retirement, and personal milestones. Count down to each one, import from Apple Calendar, and track both the days until and the days since. New: every Ahead date now has its own to-do list, so you can plan the small tasks that make the date happen and check them off as it approaches. Share an Ahead date with a friend, follow it side by side, comment, and add to-dos together on joint dates. PLANNER Planner pulls everything that matters into one beautiful, time-first view: your habits, streaks, Ahead dates, Apple Calendar events, Apple Reminders, weather, sleep, and workouts, together at last. Not another calendar, but a clear, calm picture of what the day is actually asking of you. Because everything lives in one place instead of five apps, Planner is a quiet ally for ADHD minds: see the whole day at a glance and miss nothing. Two new widgets come with it: a Planner widget and a Calendar widget for your Home Screen. POMODORO FOCUS A calm Pomodoro timer inside Left. Choose your focus and break lengths and one of four timer styles, start a session in a tap, and follow it live from your Lock Screen, widgets and the Dynamic Island. Your focus history is all there too. FASTING TOOL A simple yet beautiful fasting tool inside Left. Pick a fasting window, start it in a tap, and follow every fast live from your Lock Screen, widgets and the Dynamic Island. Your history and stats are all there too. WHY LEFT Other apps give you habits without design, or aesthetics without depth. Left combines both: the widget range, the design quality, and the full set of time tools, in one app made with restraint and taste. Left requires a Premium plan to use its features. Choose a weekly, yearly plan or a one-time lifetime purchase to unlock everything. Terms: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
