Real numbers, not guesses

Every day, colored the moment you log it.

Set a daily target once. From then on, every day goes green, amber, or red on its own — food minus whatever you burned.

  • Applies automatically from the day you set it forward
  • Activity calories already subtracted — your real balance

A real ETA, not a generic formula.

Kalendo estimates your basal rate from your height, age and activity level, then compares it to your real last 7 days.

  • Updates every time you log, no manual recalculation
  • Warns you if your trend is heading the wrong way
