Accuracy and limits
A phone camera is useful for tracking change over time. It is not a clinic. This page says what each tool does, how far to trust it, and when to see a doctor.
Seek urgent care for chest pain, trouble breathing, fainting, sudden weakness, face drooping, severe bleeding or thoughts of self-harm. Call 112.
| Tool | What it estimates | Limits |
|---|---|---|
| Full-body scan | Body fat, muscle, weight, measurements, posture | Estimated from your outline and the height you enter. Clothing, lighting and pose change results, and body fat can be off by several percentage points. Use it for trends, not a verdict. A DEXA scan or clinic test is more reliable. |
| Face and skin scan | Visible skin concerns, care plan | Cannot diagnose skin conditions or skin cancer. Show any changing mole, wound or rash to a doctor. |
| Teeth scan | Visible signs of decay, plaque, gum problems | Cannot see between teeth, under fillings or inside roots. Only a dentist with X-rays can confirm. |
| Camera pulse | Resting heart rate from a fingertip | Fair at rest, less reliable when moving or with cold fingers. Cannot detect heart disease or rhythm problems. |
| Blood pressure | Only the readings you type in | A phone camera cannot measure blood pressure. Use an upper-arm cuff. |
| Camera coach | Rep counting and form feedback | Works best with the whole body in view. It can miss errors and is not a physiotherapist. |
| Aria (AI assistant) | General information, possible causes, a report for your doctor | Can be wrong or incomplete, cannot examine you and does not know your full history. Does not prescribe or give medication doses. |
What phones cannot do
Blood tests, cancer screening, ultrasound, X-ray, ECG and heart scans need clinical equipment. See our check-up package for tests done in a hospital.
