A trainer that knows your numbers
Your AI fitness trainer reads your age, weight, height and activity level, then sets a calorie budget that fits your body — not a generic 1,200 or 2,000.

Features
Everything a personal trainer does, without the appointment
Calorie tracking, an AI diet planner and a workout plan that all read from the same set of numbers — yours.
Log food with a photo
Snap the plate or type what you ate. The AI estimates calories, protein, carbs and fat in seconds, and you can fix the portion before it saves.
A diet plan you will actually eat
Breakfast, lunch, dinner and snacks planned around your target, with swaps for the days you eat out or train late.
Workouts for home or gym
A weekly split matched to your goal and your equipment — bodyweight at home, or a full gym programme with progressive overload.
Progress you can see
Weight trend, measurements and a seven-day calorie chart, so you know whether the plan is working before the scale moves.
Targets that adapt
Change your goal, pace or activity level and every number — calories, macros, meals — recalculates around the new plan.
Diet plans
Plan your diet around the goal you actually have
Pick a goal and the whole app reshapes around it — calorie target, macro split, meal plan and training. Change your mind later and every number follows.
Diet for fat loss
Calorie deficit
A controlled deficit below your maintenance calories, with protein held high so the weight you lose is fat rather than muscle.
- Deficit sized to the pace you choose
- 2.2 g protein per kg of bodyweight
- High-volume meals that keep you full
Diet for muscle gain
Lean surplus
A modest surplus and a training plan built for progressive overload — enough to build with, small enough to stay lean.
- Controlled calorie surplus
- 2 g protein per kg of bodyweight
- Carbs timed around training
Diet for weight gain
Higher surplus
For anyone who struggles to eat enough. Calorie-dense meals and a bigger surplus, so gaining weight stops being a daily fight.
- Larger daily surplus
- Calorie-dense food picks
- Smaller, more frequent meals
Maintenance diet
Hold your shape
You are happy with where you are. Eat at maintenance, keep training, and let the tracker catch the drift before it becomes a problem.
- Calories set at your TDEE
- Balanced macro split
- Weekly trend at a glance
How it works
Three steps from signing up to a plan
No consultation to book and no spreadsheet to build. Answer a few questions and your numbers are waiting on the dashboard.
- 01
Tell us about your body
Age, sex, height, weight and how active your week really is. Body fat and measurements are optional, and make the estimate sharper.
- 02
Pick a goal and a pace
Fat loss, muscle gain, weight gain or maintain — then gradual, moderate or aggressive. We show what each one means in kilos per week.
- 03
Eat, log, and watch it move
Your calorie ring, macro split, diet plan and workout plan are ready. Log meals by photo or text and the numbers update as you go.
The maths
No guessing, and nothing hidden
Most calorie apps hand you a number and leave you to trust it. Cal Val Analyzer shows the whole calculation — where your budget comes from, what changes it, and why your macros are split the way they are.
Understanding the number is what keeps people consistent with it long after the motivation of week one has worn off.
- BMR
- What your body burns at complete rest, from the Mifflin-St Jeor equation using your weight, height, age and sex.
- TDEE
- Your BMR multiplied by an activity factor between 1.2 and 1.9 — the calories you burn on a normal day, training included.
- Your target
- TDEE adjusted for your goal and pace: a deficit for fat loss, a surplus for gaining, maintenance if you are holding steady.
- Macro split
- Protein set per kilo of bodyweight, fat at roughly 27% of calories, and the rest as carbs to fuel your training.
FAQ
Questions people ask before signing up
How the calorie maths, the diet plans and the food logging actually work.
What is an AI fitness trainer?
It is a coach that works from your data instead of a template. Cal Val Analyzer calculates what your body burns, sets a calorie and macro target for your goal, plans your meals and workouts around it, and adjusts as your weight and activity change — the work a personal trainer and a dietitian would do between sessions.
How do you calculate my daily calories?
We use the Mifflin-St Jeor equation for your basal metabolic rate (BMR), multiply it by an activity factor between 1.2 and 1.9 to get your total daily energy expenditure (TDEE), then add or subtract calories based on your goal and the pace you chose. The app shows you the whole calculation, not just the final number.
Can it plan a diet for fat loss?
Yes. Choose fat loss and you get a calorie target below your maintenance level, a protein target of about 2.2 g per kg of bodyweight to protect muscle, and a daily meal plan that fits the budget. You pick how fast: roughly 0.25, 0.5 or 0.75 kg a week.
Do I have to weigh every meal?
No. Photo logging estimates a plate in a couple of seconds, and text entry understands ordinary descriptions like two rotis and a bowl of dal. You can edit any portion before it is saved, so weighing food is an option rather than a requirement.
Does it work for vegetarian or Indian diets?
Yes. Meal suggestions are built from the food you actually eat, and the food AI recognises regional dishes rather than only packaged Western products.
Is it free to get started?
Yes. Create an account, finish the short setup, and your calorie budget, macro split, diet plan and workout plan are generated straight away.
