If you hated math, then calculators were your best friends. That hasn’t changed for the adults in us. From the ancient abacus to the latest smartphone app, the humble calculator has helped you keep track of large numbers. But thanks to the web, a calculator isn’t always about math or arithmetic.
Here are five useful but cool online calculators that can help you stay on top of your time, habits, sleep, and life itself.
Free Time Calculator: Visualize Your Free Time
About 40% of our time is spent sleeping. That’s a big but necessary chunk of your life. What about the rest? This free online calculator is a simple project by Erik Rood (who is a People Analyst at Google) that visualizes the total “free” time left in your life. The calculator is for everyone. It can be an early lesson on how to make all those free hours more meaningful.
This helps put into perspective sensitivity to things like working hours, commute, etc and how those factors stack up into a big time sink over long periods.
You can track your productivity with time management apps like RescueTime. But the Free Time Calculator gives you the big picture. Look at the graph and decide what you are going to do with the free time you have. Maybe, use it for personal growth and spend a little less time on social media .
Make Yourself Great Again: Take a Digital Look in the Mirror
This free calculator takes the idea of the time and chops it into the details. It is designed to make you reflect on your lifestyle choices and the time you are spending on them. It is a personal calculator to help you find the average time you spend on distractions and opportunities.
Examples of the former include social media, commuting, TV etc. Opportunities include learning new skills, relationships, self-reflection etc. Each box also suggests approximate hours per week an average person spends on each activity. Track your time spent and use these as a rough benchmark for your own.
You can enter your own activities too. Enter the average time in each box and the calculator will spew out a balance sheet. You are good if good habits outweigh the bad. If not, then you have some tweaks to make.
