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/

WhenThing is a tracking tool that aims to be clean, simple, and unobtrusive. It can be used to track and to anaylse patterns in personal behaviour, your health, or almost anything around you. WhenThing was designed out of a desire for a tool to easily and quietly track certain personal events and patterns. It is at least a little opinionated about the use of a habit tracker in general, with several key things in mind: - Do One Thing™: All patterns start with one event. The tiniest thing is progress. Not a real trademark. - Introspection is power: Change is easier to achieve when you know what you are changing. With those things in mind, what I didn't want to do with this app is make judgements about how the tool must be used beyond that, or about what people find helpful or hurtful. There are no nags, no reminders, no pep-talks, no gamification. We do enable you to set goals for the things you're tracking, and there's some analysis there that you can look at, but you don't get any badges! Big or small, anything is helpful here. Want to remember every time you pulled weeds out of the garden bed? Track it! Need to note when you took that medication so you don't take it again, and you don't want The Man to see? Track it! How do you feel, on a scale of 1-10? What does 10 mean? What if 10 means something different tomorrow? We take that question away with Relative Level Things. Instead of picking a 1-10 value, pick a value relative to the last value you recorded. We can still graph it, don't worry. It's not the number that counts, it's the direction it's going in. Or maybe not: You decide! Maybe you want to know how much your knees hurt after you've pulled weeds out of that garden bed? Well, have a look at a chart of "Knee pain" overlaid with "Weeding". There are any number of combinations to track, that fun is up to you! Want to bring data from another source and use it in WhenThing? Or get your data out of the app and use it somewhere else? We've enabled data import and export in CSV or JSON format. WhenThing is free to use, for tracking up to three Things (we capitalise Thing here!), and a small payment unlocks import/export and lets you add as many Things as you need.
