See Life in Numbers — How Much of Your Life You've Used in action
Life in Numbers
Enter your age, your average sleep hours per night and your daily screen time, and this tool does the real arithmetic: age × (hours per day ÷ 24) for each habit, converted into years of your life. It's a genuinely accurate way to see where the years have actually gone.
The result is shown as a big shareable card with a count-up animation, alongside a rough estimate of your total heartbeats so far based on a commonly cited average resting heart rate.

Can I use decimals?
Yes, both sleep and screen time accept half-hour increments.
Does it account for naps or weekends differently?
