How much time do you have left? Enter your date of birth and your life expectancy, and LIFE LEFT makes the answer visible: your life in months, as a 24-hour clock, and as a countdown that never stops. A simple memento mori app for anyone who wants to spend their time on what actually matters. Not recommended if you'd rather not hear the clock ticking. ■ What you see ・Month Blocks – your whole life in months. Filled blocks are behind you; empty blocks are what's left. ・Life Clock – if your life were a single day, what time would it be right now? ・Countdown – the years, weeks, days, hours and minutes you have left. ・This Year – how much of this year is still ahead of you. ・Waking hours – set your average sleep and see only the hours you are actually awake. ■ Who it's for ・For anyone who feels the days slipping past and wants to start over. ・For anyone drawn to memento mori, Stoicism and the "Die with Zero" mindset. ・For anyone planning a bucket list, a career change, or simply a better week. ■ Hard Mode (one-time purchase, optional) ・Once a month, a notification tells you that another block of your life is gone. Blunt, honest, and not for everyone. ・Home Screen widgets that keep your remaining time in view. ・Color themes. ・No ads. Your remaining time is only an estimate. What you do with it is up to you.

This app helps you turn your diagnosis into real, daily behavior. 【About】 Our energy levels, sleepiness, and performance are strongly influenced by our body clock (chronotype).

We analyze whether you lean toward a morning, intermediate, or evening type and identify your most productive time periods. ■ Time-Based Action Guide Easily see when you are likely to focus best, when to rest, and when to take things more lightly. This app is designed to be useful in daily life—not just a one-time test. ■ Real-Time Advice Get simple action tips based on your current time of day.

Verdict
The clearest difference is price: Time Left at Free against Body Clock's $1.99. Time Left also leads on iOS requirement (16.6 vs 18.2). Body Clock's advantage is in-app purchases (none vs 1) and ads (none vs shown). On update cadence and device support there is nothing between them.
