tiny fun lab

Tiny Fun Lab is a free collection of interactive calculators and experiments. Discover how many times your heart has beaten with Life Stats, calculate how many summers you have left with The Last Time, or see which future milestones you'll witness with What Will You Miss?

Find out how much your data is worth to Big Tech with Your Internet Worth, compare your life across 40+ countries with Parallel Lives, or convert your phone usage into a dollar receipt with Screen Time Receipt.

Try the Feed Your Body food simulator to see how 7 days of eating affects your virtual body, or test your vocal range against famous singers with Voice Ranger.

Everything runs entirely in your browser — no sign-ups, no data collection, no tracking. Just fun, free interactive experiments powered by real data from the UN, World Bank, and other public sources.
