Your calorie
story.
Log what you eat. Track how you train. Build the story of your best self.
Get fit with AI-powered tracking.
CalStory turns plain-English meal descriptions into logged calories and macros in seconds — then continuously adapts your calorie and macro targets to your metabolism.
Zero Friction. Maximum Results.
Most trackers fail because they're too slow. CalStory is optimized for speed, so you spend less time logging and more time training.
Why CalStory is the best calorie and macro tracker
Log meals in seconds with AI
CalStory turns "I had two eggs, toast, and a protein shake" into a saved entry in under five seconds. Our AI food logger understands plain English then estimates calories and macros against a nutrition database. You confirm before anything is committed, so the numbers stay yours — not the model's.
Hit your macros without spreadsheets
Calorie targets, protein floors, and macro splits update in real time as you log. The calorie ring on the dashboard shows what's left for the day; macro pills show whether you're ahead or behind on protein, carbs, and fat. No mental math, no forgotten cells in a Google Sheet.
Track every set, every workout
Strength sessions, HIIT, cardio, yoga, sports — CalStory's schema-driven workout form logs sets, reps, and weight for resistance work, distance and pace for cardio, and duration for everything else. Save workouts as templates and re-log them with one tap.
See real progress, not just numbers
The Progress page turns your logs into a 16-week consistency heatmap, a calorie-vs-TDEE chart, weekly energy averages, and weight-trend tracking. Spot patterns. Catch stalls. Adjust before frustration sets in.
Built for lifters, runners, and everyone in between
CalStory is opinionated about strength training — but the tracking model is generic enough to work for runners logging mileage, cyclists tracking TSS, or anyone who wants to know whether they ate enough protein this week. The TDEE calculator uses the Mifflin-St Jeor equation and refines its estimate as you log weight over time.

Your free calorie tracker, calorie counter, and workout log
What is a calorie?
A calorie is the unit of energy your body burns just by breathing, moving, and functioning — and the unit you take back in with food. Eat more than you burn and you gain weight; eat less and you lose it. That energy balance is what CalStory tracks first.
What is a calorie deficit?
A calorie deficit means consistently burning more than you consume — the mechanism behind every successful weight-loss plan. Done right, it's a modest 300–500 calorie gap below maintenance, not starvation or hours of extra cardio.
Calorie & maintenance calorie calculator
Our calorie calculator uses the Mifflin-St Jeor equation, the most accurate standard BMR formula, to set your maintenance calories. From there it becomes a calorie deficit calculator that recalibrates weekly as your logged weight changes.
A calorie counter built for speed
Describe a meal in plain language and the AI logger turns it into a saved calorie and macro entry in under nine seconds — nothing commits without your confirmation. It also remembers your regulars for one-tap re-logging.
Workout routines and a workout log
Tracking alone doesn't change a body — training does. The workout log captures every set and rep, and you can save any workout routine as a template to re-log with one tap, whatever split you follow.
Putting it all together
Your tracker shows what you ate, your log shows what you did, and Progress shows what changed — a 16-week heatmap surfaces patterns like a slump after a holiday. Read more on calorie tracking for beginners. It's free, fast, and yours.
