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. 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/

Your phone can wait. This moment can't. Lucciola turns the time you spend away from your screen into something you can watch grow: a living tree, lit by a tiny firefly. Put your phone down and the light comes on. Stay present, and your tree blossoms. No guilt. No harsh lockouts. Just a small, glowing reason to be here now. HOW IT WORKS 1. Choose how long you want to stay off your phone - five minutes or a whole evening. 2. Set it aside. Lock the screen or turn it off - that's fine. Your tree keeps growing. 3. Finish the session and collect seeds, vitality and a longer daily streak. Switch to another app mid-session and your tree quietly wilts. Nothing more. Lucciola never shames you - it just gives you a gentle reason to come back to the moment. WHY IT WORKS WHEN OTHER APPS DON'T • Kindness over pressure. No red warnings, no failure screens - a firefly, a tree and honest feedback. • A tree that remembers you. Care for it every day and it thrives. Neglect it and it slowly fades - a living reason to return. • Real stakes, zero stress. Seeds you earn buy water, fertilizer and small surprises for your tree. • Your progress at a glance. Daily streaks, total focused time, longest session and more. MADE FOR REAL LIFE • Deep work and study without the pull of notifications • Meals where phones stay face down • Evenings that end with a book instead of a feed • Time with the people you don't want to miss LUCCIOLA PLUS When you're ready for more: • No ads • Ambient focus sounds - ocean waves, birdsong, a quiet forest and more • 100 bonus seeds every month • Direct support for a small independent studio MADE WITH CARE Lucciola doesn't compete for your attention - it gives it back. It was built by a small studio with one goal: to help you put your phone down and feel good about it. Grow your focus. Grow your tree. Let your firefly shine.
