Free Weight Loss Tracker App — Calories In & Out

Fat loss is one equation

Calories in − Calories out = Weight change

Everything else — meal timing, carb levels, fasting windows, supplements — only matters insofar as it helps you hold that equation in deficit consistently. Trakon instruments both sides so you are working with data rather than assumptions.

📷

Calories in

Point your camera at a meal for instant calorie and macro estimates, or search and log manually.

📍

Calories out

GPS activity tracking plus daily steps, so movement is counted automatically.

📉

Weight trend

A smoothed trend line that ignores day-to-day water fluctuations and shows the real direction.

Why the scale lies to you daily

Your weight can swing 1–2 kg in 24 hours with zero change in body fat. Causes include:

Water retention — from salt, heat, hormones or a hard training session
Glycogen — each gram of stored carbohydrate binds roughly 3 g of water
Gut contents — food in transit weighs what it weighs
Hormonal cycle — menstrual cycle shifts can mask 1–2 weeks of real fat loss

This is why one bad morning makes people abandon a diet that was working. A trend line over 7–14 days removes the noise and shows the signal.

How to weigh yourself properly

Same time each morning, after using the bathroom, before eating or drinking
Minimal clothing, same scale, same surface
Judge only the weekly average against the previous week

Set your targets before you start

Guessing your calorie target is the fastest way to stall. Work it out first:

1. TDEE CalculatorFind your maintenance calories 2. Calorie Deficit CalculatorChoose a pace and target date 3. Macro CalculatorSplit calories into protein, carbs, fat 4. Protein CalculatorProtect muscle while cutting

Then protect your muscle

In a deficit your body will use some muscle for fuel unless you give it reasons not to. Two levers: eat 1.8–2.2 g of protein per kg of bodyweight, and do resistance training two to three times weekly. Log sessions with the workout tracker.

Losing 10 kg of which 8 kg is fat looks and feels entirely different from losing 10 kg of which 5 kg is muscle — even though the scale reads identically.

Frequently asked questions

Is Trakon free for weight loss tracking?

Yes. AI food scanning, calorie logging, GPS activity tracking and weight trend charts are all available free on iOS and Android.

How accurate is the AI food scanner?

It is good at identifying foods and estimating typical portions, but any visual estimate carries a margin of error, particularly for mixed dishes, sauces and cooking oils. Verify portions for calorie-dense items and treat totals as close approximations.

How fast should I lose weight?

For most people 0.5–1% of bodyweight per week is a good target — roughly 0.35–0.7 kg for someone at 70 kg. Faster loss increases muscle loss and rebound risk.

Why has my weight stopped changing?

Common causes are metabolic adaptation as a lighter body burns less, portion creep as tracking gets looser, water retention masking real fat loss, and reduced daily movement. Recalculate TDEE at your new weight and tighten logging for two weeks before changing anything drastic.

Do I need to log food forever?

No. Most people track closely for 8–12 weeks to learn portion sizes and calorie density, then move to looser tracking or occasional check-ins to maintain awareness.
