Calories aren't just a number.
They're time.
Calories is Time turns what you eat into the movement it takes to work it off, so a number on a label finally means something you can picture.
420 kcal
52 min
of movement
Illustrative example. Your own numbers will differ.
420 CALORIES
52 MINUTES
Suddenly, the number means something.
How it works
Track what you eat. Understand what it takes.
Track the food
Log what you eat throughout the day.
Convert it to time
See what each meal represents in working time.
See the bigger picture
Understand how individual choices add up over time.
Make better decisions
Use that perspective to decide what is actually worth it.
Why time
You already understand time.
Most people don't feel what 500 calories means. But everyone feels the difference between 10 minutes and an hour. Calories is Time borrows that instinct instead of fighting it.
10 min
barely notice it
30 min
a real chunk of your evening
1 hr
an hour you'd plan around
Movement
The other half of the number
The workout-to-calorie converter takes what you logged and estimates how long it'd take to move it off, a rough, honest gut-check, not a training plan.
Walking
~12 min per 100 kcal
Cycling
~8 min per 100 kcal
Running
~5 min per 100 kcal
Illustrative general paces. An estimate for awareness, not a personalized fitness calculation.

The Idea, In One Picture
Everything comes back to time.
Time

Made by Gerald
I’m Gerald, the student behind Cheese. I never really understood what calories meant; they were just numbers on a label. Then I started thinking about them as time, how long it would take to work them off. Calories is Time turns that idea into a simple Notion system you can actually understand and use.
Make your calories mean something.
Track the food. Track the movement. See the time.

What makes Cheese different
You only get one life. Build it well.
I don't think your money, school, habits, health, and goals are separate problems. They're all pieces of the same life.
That's why I build Cheese differently. Instead of giving you another app to manage, I make Notion systems that help you organize the things that matter, make progress on them and actually enjoy the process a little more.
Because you only get one life. It deserves a system built around it.

No, the log works with rough estimates just fine. Precision is optional, consistency is what the dashboard is built around.

What's new
Product updates
Plans and reality, kept apart
A workout you planned and a workout you finished are now two different things, and goals count the finished ones on their own.
- New Workout Log. Workout Sessions holds what you intend to do; the Workout Log holds what you actually did. Pressing Done on a plan writes the entry and moves the plan on, so a session you skipped never quietly counts as finished.
- Goals know what they are counting. Set a goal's type to Workout or Calories and its progress bar fills itself from your finished workouts, rather than from a number you keep updating by hand.
- Repeating goals. Tick Repeats on something like four workouts a week and it counts the current period, then starts again. Anything that is not a Workout or Calories goal measures the time between its start and due dates instead.
- New template guide. Setting it up, what every property and database does, and customization ideas with the steps to build them.
Your turn
How is Calories is Time going?
A star rating is all I need. Everything else is optional, so add as much or as little as you want.
