Why guessing calories is useful
You cannot track everything forever, but a rough calorie sense sticks with you. Once you know a doughnut is roughly three apples, or that a splash of oil rivals a slice of bread, everyday choices get easier without any weighing or logging. These games train exactly that instinct.

Frequently asked questions
Are these games accurate?
The calorie values are rounded approximations for everyday portions and vary by brand and preparation. They are close enough to build a useful sense of scale, which is the real point.
Do I need an account?
No. The games run in your browser, nothing is saved and there is no sign-in. If you want to actually track what you eat, that is what the TempoLife app is for.
How do I get better at guessing calories?
Notice the big drivers: fat and sugar pack the most calories per gram, and portion size usually matters more than the food itself. The cheat sheet on this page is a good place to start.
Turn the game into a habit
TempoLife logs what you eat in seconds and shows the calories — no more guessing, unless you want to.
