How accurate are the numbers?

We'd rather tell you plainly than let a confident-looking figure mislead you.

What you see	How it's produced, and how much to trust it
Calorie & macro targets	Calculated from a standard equation using your height, weight, age, sex, goal and training frequency. Equations describe populations, not individuals — yours could reasonably be several hundred calories out. Treat it as a starting point and adjust based on what actually happens over a few weeks.
Barcode scans	The most reliable figures in the app. They come from product databases, though entries are crowd-sourced and occasionally wrong. Check against the packet if a number looks odd.
Meal photos & typed meals	AI identifies the foods and estimates portions from an image or a description. It cannot weigh anything or see inside a sauce. Errors of 20–40% on a portion are entirely possible — which is exactly why every item stays editable before you log it.
Calories burned	Estimated from your logged sets, the type of movement and your bodyweight, using published metabolic values. These are population averages and are commonly 20–30% out for an individual. Where your Apple Watch has recorded a heart-rate-based figure, we use that instead — it's better, though still an estimate.
Body map & muscle scores	A record of training consistency, not a body composition measurement. It reflects which muscle groups your logged exercises have hit and how recently. It says nothing about your muscle mass, body fat or health.
Sleep rating	Read from Apple Health and scored on duration and consistency only. It is not a clinical sleep assessment and cannot detect a sleep disorder.
BMI	A crude height-to-weight ratio. It does not distinguish muscle from fat and is a poor guide for anyone who trains seriously.

About the AI coaches

The Meal Coach and Training Coach are AI. They are good at general programming and nutrition principles, and they take your goal, equipment and preferences into account. They are also capable of being fluently, confidently wrong.

• They cannot see you, assess your technique, or notice you're compensating for a weak side.
• They cannot diagnose pain and must never be asked to.
• They only know what's in your profile and what you've told them.
• They can suggest an exercise that isn't right for your body on a given day.

Use them the way you'd use a knowledgeable friend, not a clinician. If an exercise hurts in a way that isn't ordinary training discomfort, stop.

Stop exercising and seek medical help if you experience

• Chest pain, pressure or tightness
• Severe shortness of breath out of proportion to the effort
• Dizziness, fainting or feeling like you might
• Sudden sharp joint or muscle pain, especially with a pop or a giving-way sensation
• Irregular or racing heartbeat at rest
• Confusion, blurred vision or severe headache

In the UK, call 999 for an emergency or 111 for urgent advice that isn't life-threatening.

Tracking food, and when it stops helping

Calorie tracking suits some people and harms others. For anyone with a history of disordered eating — or a tendency toward it — logging every meal and watching a number all day can make things considerably worse.

Flexodus will not set a calorie target below generally accepted safe minimums, and will not accept a goal weight outside a healthy BMI range. Those limits exist for a reason, and we won't remove them on request.

Your responsibility

You know your body better than an app does. You decide what to lift, what to eat and when to stop. By using Flexodus you accept that you exercise and eat at your own risk, and that we are not liable for injury or illness arising from choices you make using information in the app — as set out in our terms of use.
