How to Log Workouts & Calories Burned in CalorTracker

Tracking what you eat is only half of the energy-balance equation. To really understand your progress, you also need to see what you burn. CalorTracker's Activity page makes logging exercise fast — and this guide walks you through all three ways to do it, step by step.

New here? You can read the original Activity feature announcement for the big-picture overview. This post is the practical how-to.

Where to find activity logging

Open CalorTracker and tap Activity in the navigation. You'll see your daily goals for calories burned and active minutes, your logged sessions for the day, and a button to add a new activity. Everything below happens from that screen.

Method 1: Manual logging (when you know the numbers)

Use manual logging when you already have a number from a treadmill, bike computer, fitness class summary, or smartwatch.

  1. Tap Add activity.
  2. Enter a short title, like "Treadmill run" or "Spin class".
  3. Type the calories burned and active minutes.
  4. Optionally add distance, steps, and intensity.
  5. Save.

This is the most precise method because you're entering verified numbers. If your watch says you burned 420 calories in 38 minutes, log exactly that.

Method 2: AI text logging (when you'd rather just describe it)

Don't have exact numbers? Just describe what you did in plain language and let the AI estimate.

  1. Tap Add activity and choose the text option.
  2. Type something natural, for example:
  • "walked 35 minutes after lunch"
  • "ran 5 km at an easy pace"
  • "45 minute upper body weights session"
  1. CalorTracker analyzes the description and prepares an entry with an estimated calorie burn, active minutes, and intensity.
  2. Review the result, adjust anything that looks off, and save.

This is the fastest way to log when all you remember is what you did and roughly how long it lasted.

Method 3: Voice logging (hands-free after a workout)

When you're tired and sweaty at the end of a session, typing is the last thing you want to do. Speak instead.

  1. Tap Add activity and choose voice input.
  2. Say your activity out loud, like "I just cycled for 50 minutes, moderate effort."
  3. CalorTracker turns your speech into a draft activity entry.
  4. Review and save.

It's the same AI estimation as text logging — just hands-free.

Always review before you save

AI estimates are convenient, but your health data should stay accurate. Whenever CalorTracker analyzes an activity from text or voice, it shows you the result before saving so you can confirm or correct the title, activity type, active minutes, intensity, calories burned, distance, and steps. If something is off, edit it in one tap.

How burned calories fit your daily plan

Logged activity doesn't sit in isolation. Your burned calories and active minutes flow into:

  • Daily progress summaries, so you see intake vs. output.
  • Historical progress reports, to spot weekly patterns.
  • Smart Insights, which connect movement to your nutrition adherence.

A quick note on "eating back" exercise calories: if you set your calorie goal using an activity level that already assumes regular training (see our TDEE calculator), don't add all your burned calories back on top, or you'll double-count. If your goal is based on a sedentary baseline, logging workouts gives you a more accurate daily target.

Smarter hydration after movement

One of the most useful side effects of activity logging is hydration. When you log a session, CalorTracker can raise your effective water target based on your active minutes and intensity. A light walk barely moves it; a hard, sweaty workout adds a clear hydration bump — so your water goal responds to what you actually did. Want a baseline first? Try our water intake calculator.

A quick workflow that sticks

The best logging method is the one you'll actually use. A simple routine:

  1. During structured workouts, log manually from your machine or watch for precision.
  2. For everyday movement — walks, errands, a quick session — use AI text or voice and just review.
  3. Check the Activity page once a day to confirm you're hitting your active-minutes goal.

Movement is easier to stay consistent with when it's visible. Open CalorTracker, tap Activity, and log today's workout in seconds — whichever way is fastest for you.
