The short versionWhat these apps are, and what they are not

In an emergencyDo not use an app — get help now

These apps are not monitored, they are not a crisis service, and no one reads what you enter. If you or someone else is in danger, contact emergency services directly.

• Call your local emergency number immediately for chest pain, difficulty breathing, sudden weakness or numbness, sudden confusion or trouble speaking, severe bleeding, or a severe allergic reaction.
• If you are having thoughts of harming yourself, contact your local emergency number or a crisis line in your country now. The international directory at findahelpline.com lists free, confidential services by country.
• MindGuardAI is a journal, not a therapist. It cannot detect a crisis, cannot call anyone for you, and must never be relied on for urgent support.

Per appWhat each app can and cannot tell you

🔬 SkinGuardAI — skin and mole records

The analysis uses a general-purpose AI vision model (Google Gemini) prompted with the ABCDE criteria. It is not a model trained or clinically validated for dermatology, and it has not been tested against biopsy outcomes. It is a structured way to describe a photograph and compare it with an older photograph of the same spot.

It is not a skin-cancer screening test. A low-concern result does not mean a lesion is benign, and it is not clearance to leave something alone. Photographs also miss what a dermatologist would find with dermoscopy and with their hands. Anything new, changing, bleeding, itching, non-healing, or simply different from your other spots should be shown to a doctor regardless of what the app said.

💪 FitGuardAI — workout form

Pose estimation from a camera gives general movement cues. It does not know your injuries, your joints, your medical history or your training load, and camera angle, clothing and lighting all change what it sees. It is not physiotherapy and not a personal trainer. Stop if a movement hurts, and get advice before training through pain.

🏥 RehabGuardAI — rehabilitation

Guidance and range-of-motion tracking to support a recovery programme — not to replace one. If a clinician has prescribed a rehab programme, follow theirs. Do not use the app to decide that you are ready to return to sport, to work, or to load a healing injury.

🥬 MealGuardAI — meals and nutrition

Recipe and nutrition suggestions, not clinical dietetics. Nutrition figures are estimates. Ingredient and allergen recognition can be wrong or incomplete, so never rely on it to keep yourself safe from an allergen. Always read the actual product label. If you have a medically managed diet — diabetes, kidney disease, coeliac disease, an eating disorder, pregnancy — talk to your doctor or dietitian before changing what you eat.

🧠 MindGuardAI — mood journal

A private place to record how you feel and notice patterns over time. It is not therapy, not a mental-health assessment, not a diagnosis, and not a crisis service. It cannot tell you whether you have a condition, and it must never be used to decide anything about psychiatric medication.

WhyThe limits of the AI itself

Being specific about this is more useful than a warning label, so:

• These are general-purpose models. They were not trained for medicine and have not been clinically validated for any of these uses.
• They can be confidently wrong. Fluent, well-structured, plausible output is not evidence of accuracy, and the tone of an answer says nothing about how reliable it is.
• They see one input, not you. A photo or a sentence carries no history, no examination, no bloodwork and no context. A clinician has all four.
• Input quality changes the answer. Lighting, focus, distance, skin tone, camera angle and how a question is phrased can all move the result.
• The same input can give different answers. These models are not deterministic, and repetition is not confirmation.
• False reassurance is the real risk. The dangerous failure is not an alarming result — it is a calm one that persuades someone not to get something looked at.

PleaseSee a professional when it matters

Use the apps to notice things and to keep a record. Use a clinician to interpret them. Seek medical advice promptly — whatever any app has told you — if you notice a mole or skin lesion that is new, changing, asymmetric, irregularly bordered, multi-coloured, growing, itching, bleeding or not healing; pain that is new, severe or worsening; unexplained weight loss; a lump; persistent fatigue; any symptom that is getting worse rather than better; or any change in mood, thinking or behaviour that is frightening you or the people around you.

Bringing your records with you helps. A dated series of photographs, or a few months of mood entries, is genuinely useful to a clinician — that is the best thing these apps do.
